merge: cache negative cache results for similarity metrics
When computing renames, we cache the hash signatures for each of the
potentially conflicting entries so that we do not need to repeatedly
read the file and can at least halfway efficiently determine whether two
files are similar enough to be deemed a rename. In order to make the
hash signatures meaningful, we require at least four lines of data to be
present, resulting in at least four different hashes that can be
compared. Files that are deemed too small are not cached at all and
will thus be repeatedly re-hashed, which is usually not a huge issue.
The issue with above heuristic is in case a file does _not_ have at
least four lines, where a line is anything separated by a consecutive
run of "\n" or "\0" characters. For example "a\nb" is two lines, but
"a\0\0b" is also just two lines. Taken to the extreme, a file that has
megabytes of consecutive space- or NUL-only may also be deemed as too
small and thus not get cached. As a result, we will repeatedly load its
blob, calculate its hash signature just to finally throw it away as we
notice it's not of any value. When you've got a comparitively big file
that you compare against a big set of potentially renamed files, then
the cost simply expodes.
The issue can be trivially fixed by introducing negative cache entries.
Whenever we determine that a given blob does not have a meaningful
representation via a hash signature, we store this negative cache marker
and will from then on not hash it again, but also ignore it as a
potential rename target. This should help the "normal" case already
where you have a lot of small files as rename candidates, but in the
above scenario it's savings are extraordinarily high.
To verify we do not hit the issue anymore with described solution, this
commit adds a test that uses the exact same setup described above with
one 50 megabyte blob of '\0' characters and 1000 other files that get
renamed. Without the negative cache:
$ time ./libgit2_clar -smerge::trees::renames::cache_recomputation >/dev/null
real 11m48.377s
user 11m11.576s
sys 0m35.187s
And with the negative cache:
$ time ./libgit2_clar -smerge::trees::renames::cache_recomputation >/dev/null
real 0m1.972s
user 0m1.851s
sys 0m0.118s
So this represents a ~350-fold performance improvement, but it obviously
depends on how many files you have and how big the blob is. The test
number were chosen in a way that one will immediately notice as soon as
the bug resurfaces.

cmake: use install directories provided via GNUInstallDirs
We currently hand-code logic to configure where to install our artifacts
via the `LIB_INSTALL_DIR`, `INCLUDE_INSTALL_DIR` and `BIN_INSTALL_DIR`
variables. This is reinventing the wheel, as CMake already provide a way
to do that via `CMAKE_INSTALL_<DIR>` paths, e.g. `CMAKE_INSTALL_LIB`.
This requires users of libgit2 to know about the discrepancy and will
require special hacks for any build systems that handle these variables
in an automated way. One such example is Gentoo Linux, which sets up
these paths in both the cmake and cmake-utils eclass.
So let's stop doing that: the GNUInstallDirs module handles it in a
better way for us, especially so as the actual values are dependent on
CMAKE_INSTALL_PREFIX. This commit removes our own set of variables and
instead refers users to use the standard ones.
As a second benefit, this commit also fixes our pkgconfig generation to
use the GNUInstallDirs module. We had a bug there where we ignored the
CMAKE_INSTALL_PREFIX when configuring the libdir and includedir keys, so
if libdir was set to "lib64", then libdir would be an invalid path. With
GNUInstallDirs, we can now use `CMAKE_INSTALL_FULL_LIBDIR`, which
handles the prefix for us.

win32: don't canonicalize symlink targets
Don't canonicalize symlink targets; our win32 path canonicalization
routines expect an absolute path. In particular, using the path
canonicalization routines for symlink targets (introduced in commit
7d55bee6d, "win32: fix relative symlinks pointing into dirs",
2020-01-10).
Now, use the utf8 -> utf16 relative path handling functions, so that
paths like "../foo" will be translated to "..\foo".

win32: clarify usage of path canonicalization funcs
The path canonicalization functions on win32 are intended to
canonicalize absolute paths; those with prefixes. In other words,
things start with drive letters (`C:\`), share names (`\\server\share`),
or other prefixes (`\\?\`).
This function removes leading `..` that occur after the prefix but
before the directory/file portion (eg, turning `C:\..\..\..\foo` into
`C:\foo`). This translation is not appropriate for local paths.

httpclient: use a 16kb read buffer for macOS
Use a 16kb read buffer for compatibility with macOS SecureTransport.
SecureTransport `SSLRead` has the following behavior:
1. It will return _at most_ one TLS packet's worth of data, and
2. It will try to give you as much data as you asked for
This means that if you call `SSLRead` with a buffer size that is smaller
than what _it_ reads (in other words, the maximum size of a TLS packet),
then it will buffer that data for subsequent calls. However, it will
also attempt to give you as much data as you requested in your SSLRead
call. This means that it will guarantee a network read in the event
that it has buffered data.
Consider our 8kb buffer and a server sending us 12kb of data on an HTTP
Keep-Alive session. Our first `SSLRead` will read the TLS packet off
the network. It will return us the 8kb that we requested and buffer the
remaining 4kb. Our second `SSLRead` call will see the 4kb that's
buffered and decide that it could give us an additional 4kb. So it will
do a network read.
But there's nothing left to read; that was the end of the data. The
HTTP server is waiting for us to provide a new request. The server will
eventually time out, our `read` system call will return, `SSLRead` can
return back to us and we can make progress.
While technically correct, this is wildly ineffecient. (Thanks, Tim
Apple!)
Moving us to use an internal buffer that is the maximum size of a TLS
packet (16kb) ensures that `SSLRead` will never buffer and it will
always return everything that it read (albeit decrypted).

streams: openssl: switch approach to silence Valgrind errors
As OpenSSL loves using uninitialized bytes as another source of entropy,
we need to mark them as defined so that Valgrind won't complain about
use of these bytes. Traditionally, we've been using the macro
`VALGRIND_MAKE_MEM_DEFINED` provided by Valgrind, but starting with
OpenSSL 1.1 the code doesn't compile anymore due to `struct SSL` having
become opaque. As such, we also can't set it as defined anymore, as we
have no way of knowing its size.
Let's change gears instead by just swapping out the allocator functions
of OpenSSL with our own ones. The twist is that instead of calling
`malloc`, we just call `calloc` to have the bytes initialized
automatically. Next to soothing Valgrind, this approach has the benefit
of being completely agnostic of the memory sanitizer and is neatly
contained at a single place.
Note that we shouldn't do this for non-Valgrind builds. As we cannot
set up memory functions for a given SSL context, only, we need to swap
them at a global context. Furthermore, as it's possible to call
`OPENSSL_set_mem_functions` once only, we'd prevent users of libgit2 to
set up their own allocators.

cmake: consolidate Valgrind option
OpenSSL doesn't initialize bytes on purpose in order to generate
additional entropy. Valgrind isn't too happy about that though, causing
it to generate warninings about various issues regarding use of
uninitialized bytes.
We traditionally had some infrastructure to silence these errors in our
OpenSSL stream implementation, where we invoke the Valgrind macro
`VALGRIND_MAKE_MEMDEFINED` in various callbacks that we provide to
OpenSSL. Naturally, we only include these instructions if a preprocessor
define "VALGRIND" is set, and that in turn is only set if passing
"-DVALGRIND" to CMake. We do that in our usual Azure pipelines, but we
in fact forgot to do this in our nightly build. As a result, we get a
slew of warnings for these nightly builds, but not for our normal
builds.
To fix this, we could just add "-DVALGRIND" to our nightly builds. But
starting with commit d827b11b6 (tests: execute leak checker via CTest
directly, 2019-06-28), we do have a secondary variable that directs
whether we want to use memory sanitizers for our builds. As such, every
user wishing to use Valgrind for our tests needs to pass both options
"VALGRIND" and "USE_LEAK_CHECKER", which is cumbersome and error prone,
as can be seen by our own builds.
Instead, let's consolidate this into a single option, removing the old
"-DVALGRIND" one. Instead, let's just add the preprocessor directive if
USE_LEAK_CHECKER equals "valgrind" and remove "-DVALGRIND" from our own
pipelines.

streams: openssl: ignore return value of `git_mutex_lock`
OpenSSL pre-v1.1 required us to set up a locking function to properly
support multithreading. The locking function signature cannot return any
error codes, and as a result we can't do anything if `git_mutex_lock`
fails. To silence static analysis tools, let's just explicitly ignore
its return value by casting it to `void`.

cache: fix invalid memory access in case updating cache entry fails
When adding a new entry to our cache where an entry with the same OID
exists already, then we only update the existing entry in case it is
unparsed and the new entry is parsed. Currently, we do not check the
return value of `git_oidmap_set` though when updating the existing
entry. As a result, we will _not_ have updated the existing entry if
`git_oidmap_set` fails, but have decremented its refcount and
incremented the new entry's refcount. Later on, this may likely lead to
dereferencing invalid memory.
Fix the issue by checking the return value of `git_oidmap_set`. In case
it fails, we will simply keep the existing stored instead, even though
it's unparsed.

worktree: report errors when unable to read locking reason
Git worktree's have the ability to be locked in order to spare them from
deletion, e.g. if a worktree is absent due to being located on a
removable disk it is a good idea to lock it. When locking such
worktrees, it is possible to give a locking reason in order to help the
user later on when inspecting status of any such locked trees.
The function `git_worktree_is_locked` serves to read out the locking
status. It currently does not properly report any errors when reading
the reason file, and callers are unexpecting of any negative return
values, too. Fix this by converting callers to expect error codes and
checking the return code of `git_futils_readbuffer`.

repository: check error codes when reading common link
When checking whether a path is a valid repository path, we try to read
the "commondir" link file. In the process, we neither confirm that
constructing the file's path succeeded nor do we verify that reading the
file succeeded, which might cause us to verify repositories on an empty
or bogus path later on.
Fix this by checking return values. As the function to verify repos
doesn't currently support returning errors, this commit also refactors
the function to return an error code, passing validity of the repo via
an out parameter instead, and adjusts all existing callers.

push: check error code returned by `git_revwalk_hide`
When queueing objects we want to push, we call `git_revwalk_hide` to
hide all objects already known to the remote from our revwalk. We do not
check its return value though, where the orginial intent was to ignore
the case where the pushed OID is not a known committish. As
`git_revwalk_hide` can fail due to other reasons like out-of-memory
exceptions, we should still check its return value.
Fix the issue by checking the function's return value, ignoring
errors hinting that it's not a committish. As `git_revwalk__push_commit`
currently clobbers these error codes, we need to adjust it as well in
order to make it available downstream.

other error codes returned by `git_iterator_advance` to catch unexpected
internal errors.

`GIT_ITEROVER`.

transports: http: fix custom headers not being applied
In commit b9c5b15a7 (http: use the new httpclient, 2019-12-22), the HTTP
code got refactored to extract a generic HTTP client that operates
independently of the Git protocol. Part of refactoring was the creation
of a new `git_http_request` struct that encapsulates the generation of
requests. Our Git-specific HTTP transport was converted to use that in
`generate_request`, but during the process we forgot to set up custom
headers for the `git_http_request` and as a result we do not send out
these headers anymore.
Fix the issue by correctly setting up the request's custom headers and
add a test to verify we correctly send them.

fetchhead: strip credentials from remote URL
If fetching from an anonymous remote via its URL, then the URL gets
written into the FETCH_HEAD reference. This is mainly done to give
valuable context to some commands, like for example git-merge(1), which
will put the URL into the generated MERGE_MSG. As a result, what gets
written into FETCH_HEAD may become public in some cases. This is
especially important considering that URLs may contain credentials, e.g.
when cloning 'https://foo:bar@example.com/repo' we persist the complete
URL into FETCH_HEAD and put it without any kind of sanitization into the
MERGE_MSG. This is obviously bad, as your login data has now just leaked
as soon as you do git-push(1).
When writing the URL into FETCH_HEAD, upstream git does strip
credentials first. Let's do the same by trying to parse the remote URL
as a "real" URL, removing any credentials and then re-formatting the
URL. In case this fails, e.g. when it's a file path or not a valid URL,
we just fall back to using the URL as-is without any sanitization. Add
tests to verify our behaviour.

http: send probe packets
When we're authenticating with a connection-based authentication scheme
(NTLM, Negotiate), we need to make sure that we're still connected
between the initial GET where we did the authentication and the POST
that we're about to send. Our keep-alive session may have not kept
alive, but more likely, some servers do not authenticate the entire
keep-alive connection and may have "forgotten" that we were
authenticated, namely Apache and nginx.
Send a "probe" packet, that is an HTTP POST request to the upload-pack
or receive-pack endpoint, that consists of an empty git pkt ("0000").
If we're authenticated, we'll get a 200 back. If we're not, we'll get a
401 back, and then we'll resend that probe packet with the first step of
our authentication (asking to start authentication with the given
scheme). We expect _yet another_ 401 back, with the authentication
challenge.
Finally, we will send our authentication response with the actual POST
data. This will allow us to authenticate without draining the POST data
in the initial request that gets us a 401.

httpclient: support expect/continue
Allow users to opt-in to expect/continue handling when sending a POST
and we're authenticated with a "connection-based" authentication
mechanism like NTLM or Negotiate.
If the response is a 100, return to the caller (to allow them to post
their body). If the response is *not* a 100, buffer the response for
the caller.
HTTP expect/continue is generally safe, but some legacy servers
have not implemented it correctly. Require it to be opt-in.

httpclient: support authentication
Store the last-seen credential challenges (eg, all the
'WWW-Authenticate' headers in a response message). Given some
credentials, find the best (first) challenge whose mechanism supports
these credentials. (eg, 'Basic' supports username/password credentials,
'Negotiate' supports default credentials).
Set up an authentication context for this mechanism and these
credentials. Continue exchanging challenge/responses until we're
authenticated.

httpclient: consume final chunk message
When sending a new request, ensure that we got the entirety of the
response body. Our caller may have decided that they were done reading.
If we were not at the end of the message, this means that we need to
tear down the connection and cannot do keep-alive.
However, if the caller read all of the message, but we still have a
final end-of-response chunk signifier (ie, "0\r\n\r\n") on the socket,
then we should consider that the response was successfully copmleted.
If we're asked to send a new request, try to read from the socket, just
to clear out that end-of-chunk message, marking ourselves as
disconnected on any errors.

httpclient: introduce a simple http implementation
Introduce a new http client implementation that can GET and POST to
remote URLs.
Consumers can use `git_http_client_init` to create a new client,
`git_http_client_send_request` to send a request to the remote server
and `git_http_client_read_response` to read the response.
The http client implementation will perform the I/O with the remote
server (http or https) but does not understand the git smart transfer
protocol. This allows us to split the concerns of the http subtransport
from the actual http implementation.

gssapi: protect GSS_ERROR macro
The GSS_ERROR(x) macro may expand to `(x & value)` on some
implementations, instead of `((x) & value)`. This is the case on macOS,
which means that if we attempt to wrap an expression in that macro, like
`a = b`, then that would expand to `(a = b & value)`.
Since `&` has a higher precedence, this is not at all what we want, and
will set our result code to an incorrect value. Evaluate the expression
then test it with `GSS_ERROR` independently to avoid this.

index: fix resizing index map twice on case-insensitive systems
Depending on whether the index map is case-sensitive or insensitive, we
need to call either `git_idxmap_icase_resize` or `git_idxmap_resize`.
There are multiple locations where we thus use the following pattern:
if (index->ignore_case &&
git_idxmap_icase_resize(map, length) < 0)
return -1;
else if (git_idxmap_resize(map, length) < 0)
return -1;
The funny thing is: on case-insensitive systems, we will try to resize
the map twice in case where `git_idxmap_icase_resize()` doesn't error.
While this will still use the correct hashing function as both map types
use the same, this bug will at least cause us to resize the map twice in
a row.
Fix the issue by introducing a new function `index_map_resize` that
handles case-sensitivity, similar to how `index_map_set` and
`index_map_delete`. Convert all call sites where we were previously
resizing the map to use that new function.

index: replace map macros with inline functions
Traditionally, our maps were mostly implemented via macros that had
weird call semantics. This shows in our index code, where we have macros
that insert into an index map case-sensitively or insensitively, as they
still return error codes via an error parameter. This is unwieldy and,
most importantly, not necessary anymore, due to the introduction of our
high-level map API and removal of macros.
Replace them with inlined functions to make code easier to read.

win32: fix relative symlinks pointing into dirs
On Windows platforms, we need some logic to emulate symlink(3P) defined
by POSIX. As unprivileged symlinks on Windows are a rather new feature,
our current implementation is comparatively new and still has some
rough edges in special cases.
One such case is relative symlinks. While relative symlinks to files in
the same directory work as expected, libgit2 currently fails to create
reltaive symlinks pointing into other directories. This is due to the
fact that we forgot to translate the Unix-style target path to
Windows-style. Most importantly, we are currently not converting
directory separators from "/" to "\".
Fix the issue by calling `git_win32_path_canonicalize` on the target.
Add a test that verifies our ability to create such relative links
across directories.
