utf8: use size_t for length of buffer
The `git__utf8_charlen` now takes `size_t` as the buffer length, since
it contains the full length of the buffer at the current position. It
now returns `-1` in all cases where utf8 codepoints are invalid, since
callers only care about a valid length of a sequence of codepoints, or
if the current position is not valid utf8.

tree: return `size_t` for treebuilder entrycount
We keep the treebuilder entrycount as a `size_t` - return that instead
of downcasting to an `unsigned int`. Callers who were storing this
value in an `unsigned int` will continue to downcast themselves, so
there should be no behavior change for callers.

netops: safely cast to int
Only read at most INT_MAX from the underlying stream, so that we can
accurately return the number of bytes read.
Since callers are not guaranteed to get as many bytes as requested (due
to availability of input), this is safe and callers should call in a
loop until EOF.

cmake: default NTLM client to off if no HTTPS support
If building libgit2 with `-DUSE_HTTPS=NO`, then CMake will
generate an error complaining that there's no usable HTTPS
backend for NTLM. In fact, it doesn't make sense to support NTLM
when we don't support HTTPS. So let's should just have
NTLM default to OFF when HTTPS is disabled to make life easier
and to fix our OSSFuzz builds failing.

attr_file: convert to use `wildmatch`
Upstream git has converted to use `wildmatch` instead of
`fnmatch`. Convert our gitattributes logic to use `wildmatch` as
the last user of `fnmatch`. Please, don't expect I know what I'm
doing here: the fnmatch parser is one of the most fun things to
play around with as it has a sh*tload of weird cases. In all
honesty, I'm simply relying on our tests that are by now rather
comprehensive in that area.
The conversion actually fixes compatibility with how git.git
parser "**" patterns when the given path does not contain any
directory separators. Previously, a pattern "**.foo" erroneously
wouldn't match a file "x.foo", while git.git would match.
Remove the new-unused LEADINGDIR/NOLEADINGDIR flags for
`git_attr_fnmatch`.

config_file: use `wildmatch` to evaluate conditionals
We currently use `p_fnmatch` to compute whether a given "gitdir:"
or "gitdir/i:" conditional matches the current configuration file
path. As git.git has moved to use `wildmatch` instead of
`p_fnmatch` throughout its complete codebase, we evaluate
conditionals inconsistently with git.git in some special cases.
Convert `p_fnmatch` to use `wildmatch`. The `FNM_LEADINGDIR` flag
cannot be translated to `wildmatch`, but in fact git.git doesn't
use it here either. And in fact, dropping it while we go
increases compatibility with git.git.

config_file: do not include trailing '/' for "gitdir" conditionals
When evaluating "gitdir:" and "gitdir/i:" conditionals, we
currently compare the given pattern with the value of
`git_repository_path`. Thing is though that `git_repository_path`
returns the gitdir path with trailing '/', while we actually need
to match against the gitdir without it.
Fix this issue by stripping the trailing '/' previous to
matching. Add various tests to ensure we get this right.

global: convert trivial `fnmatch` users to use `wildcard`
Upstream git.git has converted its codebase to use wildcard in
favor of fnmatch in commit 70a8fc999d (stop using fnmatch (either
native or compat), 2014-02-15). To keep our own regex-matching in
line with what git does, convert all trivial instances of
`fnmatch` usage to use `wildcard`, instead. Trivial usage is
defined to be use of `fnmatch` with either no flags or flags that
have a 1:1 equivalent in wildmatch (PATHNAME, IGNORECASE).

posix: remove implicit include of "fnmatch.h"

explicitly.

wildmatch: import wildmatch from git.git
In commit 70a8fc999d (stop using fnmatch (either native or
compat), 2014-02-15), upstream git has switched over all code
from their internal fnmatch copy to its new wildmatch code. We
haven't followed suit, and thus have developed some
incompatibilities in how we match regular expressions.
Import git's wildmatch from v2.22.0 and add a test suite based on
their t3070-wildmatch.sh tests.

posix: remove `p_fallocate` abstraction
By now, we have repeatedly failed to provide a nice
cross-platform implementation of `p_fallocate`. Recent tries to
do that escalated quite fast to a set of different CMake checks,
implementations, fallbacks, etc., which started to look real
awkward to maintain. In fact, `p_fallocate` had only been
introduced in commit 4e3949b73 (tests: test that largefiles can
be read through the tree API, 2019-01-30) to support a test with
large files, but given the maintenance costs it just seems not to
be worht it.
As we have removed the sole user of `p_fallocate` in the previous
commit, let's drop it altogether.

tests: object: refactor largefile test to not use `p_fallocate`
The `p_fallocate` platform is currently in use in our tests,
only, but it proved to be quite burdensome to get it implemented
in a cross-platform way. The only "real" user is the test
object::tree::read::largefile, where it's used to allocate a
large file in the filesystem only to commit it to the repo and
read its object back again. We can simplify this quite a bit by
just using an in-memory buffer of 4GB. Sure, this cannot be used
on platforms with low resources. But creating 4GB files is not
any better, and we already skip the test if the environment
variable "GITTEST_INVASIVE_FS_SIZE" is not set. So we're arguably
not worse off than before.

cmake: Modulize our TLS & hash detection
The interactions between `USE_HTTPS` and `SHA1_BACKEND` have been
streamlined. Previously we would have accepted not quite working
configurations (like, `-DUSE_HTTPS=OFF -DSHA1_BACKEND=OpenSSL`) and, as
the OpenSSL detection only ran with `USE_HTTPS`, the link would fail.
The detection was moved to a new `USE_SHA1`, modeled after `USE_HTTPS`,
which takes the values "CollisionDetection/Backend/Generic", to better
match how the "hashing backend" is selected, the default (ON) being
"CollisionDetection".
Note that, as `SHA1_BACKEND` is still used internally, you might need to
check what customization you're using it for.

Rename opt init functions to `options_init`
In libgit2 nomenclature, when we need to verb a direct object, we name
a function `git_directobject_verb`. Thus, if we need to init an options
structure named `git_foo_options`, then the name of the function that
does that should be `git_foo_options_init`.
The previous names of `git_foo_init_options` is close - it _sounds_ as
if it's initializing the options of a `foo`, but in fact
`git_foo_options` is its own noun that should be respected.
Deprecate the old names; they'll now call directly to the new ones.

The ntlmclient dependency has quite a lot of places with implicit

implicit fallthroughs by default, the developer is greeted with a
wall of warnings when compiling that dependency.
Disable implicit fallthrough warnings for ntlmclient to fix this
issue.

http-parser has these bugfixes (using a version check).
Since these bugs are - at present - minor, retain the ability for users
to force that they want to use the system http-parser anyway. This does
change the cmake specification so that people _must_ opt-in to the new
behavior knowingly.

attr_file: remove invalid TODO comment
In our attributes pattern parsing code, we have a comment that
states we might have to convert '\' characters to '/' to have
proper POSIX paths. But in fact, '\' characters are valid inside
the string and act as escape mechanism for various characters,
which is why we never want to convert those to POSIX directory
separators. Furthermore, gitignore patterns are specified to only
treat '/' as directory separators.
Remove the comment to avoid future confusion.

attr_file: account for escaped escapes when searching trailing space
When determining the trailing space length, we need to honor
whether spaces are escaped or not. Currently, we do not check
whether the escape itself is escaped, though, which might
generate an off-by-one in that case as we will simply treat the
space as escaped.
Fix this by checking whether the backslashes preceding the space
are themselves escaped.

attr_file: fix unescaping of escapes required for fnmatch
When parsing attribute patterns, we will eventually unescape the
parsed pattern. This is required because we require custom
escapes for whitespace characters, as normally they are used to
terminate the current pattern. Thing is, we don't only unescape
those whitespace characters, but in fact all escaped sequences.
So for example if the pattern was "\*", we unescape that to "*".
As this is directly passed to fnmatch(3) later, fnmatch would
treat it as a simple glob matching all files where it should
instead only match a file with name "*".
Fix the issue by unescaping spaces, only. Add a bunch of tests to
exercise escape parsing.

attr_file: properly handle escaped '\' when searching non-escaped spaces
When parsing attributes, we need to search for the first
unescaped whitespace character to determine where the pattern is
to be cut off. The scan fails to account for the case where the
escaping '\' character is itself escaped, though, and thus we
would not recognize the cut-off point in patterns like "\\ ".
Refactor the scanning loop to remember whether the last character
was an escape character. If it was and the next character is a
'\', too, then we will reset to non-escaped mode again. Thus, we
now handle escaped whitespaces as well as escaped wildcards
correctly.

path: only treat paths starting with '\' as absolute on Win32
Windows-based systems treat paths starting with '\' as absolute,
either referring to the current drive's root (e.g. "\foo" might
refer to "C:\foo") or to a network path (e.g. "\\host\foo"). On
the other hand, (most?) systems that are not based on Win32
accept backslashes as valid characters that may be part of the
filename, and thus we cannot treat them to identify absolute
paths.
Change the logic to only paths starting with '\' as absolute on
the Win32 platform. Add tests to avoid regressions and document
behaviour.

http_parser: handle URLs with colon but no port
When the end of the host is reached, and we're at the colon separating
the host with the port (ie, there is no numeric port) then do not error.
This is allowed by RFC 3986.

net: handle urls with a colon after host but no port
Core git copes with URLs that have a colon after the port, but no actual
numeric value. eg `http://example.com:/foo.git` or
`http://example.com:`. That's horrible, but RFC 3986 says:
> URI producers and normalizers should omit the port component and its
> ":" delimiter if port is empty or if its value would be the same as
> that of the scheme's default.
Which indicates that they may and therefore we must accept it.
Test that we can handle URLs with a colon but no following port number.

sha1dc: update to fix endianess issues on AIX/HP-UX
Update our copy of sha1dc to the upstream commit 855827c (Detect
endianess on HP-UX, 2019-05-09). Changes include fixes to endian
detection on AIX and HP-UX systems as well as a define that
allows us to force aligned access, which we're not using yet.

http: free auth context on failure
When we send HTTP credentials but the server rejects them, tear down the
authentication context so that we can start fresh. To maintain this
state, additionally move all of the authentication handling into
`on_auth_required`.

http: reconnect to proxy on connection close
When we're issuing a CONNECT to a proxy, we expect to keep-alive to the
proxy. However, during authentication negotiations, the proxy may close
the connection. Reconnect if the server closes the connection.

http: allow server to drop a keepalive connection
When we have a keep-alive connection to the server, that server may
legally drop the connection for any reason once a successful request and
response has occurred. It's common for servers to drop the connection
after some amount of time or number of requests have occurred.

http: stop on server EOF
We stop the read loop when we have read all the data. We should also
consider the server's feelings.
If the server hangs up on us, we need to stop our read loop. Otherwise,
we'll try to read from the server - and fail - ad infinitum.

http: teach auth mechanisms about connection affinity
Instead of using `is_complete` to decide whether we have connection or
request affinity for authentication mechanisms, set a boolean on the
mechanism definition itself.

http: maintain authentication across connections
For request-based authentication mechanisms (Basic, Digest) we should
keep the authentication context alive across socket connections, since
the authentication headers must be transmitted with every request.
However, we should continue to remove authentication contexts for
mechanisms with connection affinity (NTLM, Negotiate) since we need to
reauthenticate for every socket connection.

http: simplify authentication mechanisms
Hold an individual authentication context instead of trying to maintain
all the contexts; we can select the preferred context during the initial
negotiation.
Subsequent authentication steps will re-use the chosen authentication
(until such time as it's rejected) instead of trying to manage multiple
contexts when all but one will never be used (since we can only
authenticate with a single mechanism at a time.)
Also, when we're given a 401 or 407 in the middle of challenge/response
handling, short-circuit immediately without incrementing the retry
count. The multi-step authentication is expected, and not a "retry" and
should not be penalized as such.
This means that we don't need to keep the contexts around and ensures
that we do not unnecessarily fail for too many retries when we have
challenge/response auth on a proxy and a server and potentially
redirects in play as well.

http: don't reset replay count after connection
A "connection" to a server is transient, and we may reconnect to a
server in the midst of authentication failures (if the remote indicates
that we should, via `Connection: close`) or in a redirect.

http: validate server's authentication types
Ensure that the server supports the particular credential type that
we're specifying. Previously we considered credential types as an
input to an auth mechanism - since the HTTP transport only supported
default credentials (via negotiate) and username/password credentials
(via basic), this worked. However, if we are to add another mechanism
that uses username/password credentials, we'll need to be careful to
identify the types that are accepted.

http: consume body on proxy auth failure
We must always consume the full parser body if we're going to
keep-alive. So in the authentication failure case, continue advancing
the http message parser until it's complete, then we can retry the
connection.
Not doing so would mean that we have to tear the connection down and
start over. Advancing through fully (even though we don't use the data)
will ensure that we can retry a connection with keep-alive.

http: always consume body on auth failure
When we get an authentication failure, we must consume the entire body
of the response. If we only read half of the body (on the assumption
that we can ignore the rest) then we will never complete the parsing of
the message. This means that we will never set the complete flag, and
our replay must actually tear down the connection and try again.
This is particularly problematic for stateful authentication mechanisms
(SPNEGO, NTLM) that require that we keep the connection alive.
Note that the prior code is only a problem when the 401 that we are
parsing is too large to be read in a single chunked read from the http
parser.
But now we will continue to invoke the http parser until we've got a
complete message in the authentication failed scenario. Note that we
need not do anything with the message, so when we get an authentication
failed, we'll stop adding data to our buffer, we'll simply loop in the
parser and let it advance its internal state.

transports: add an `is_complete` function for auth
Some authentication mechanisms (like HTTP Basic and Digest) have a
one-step mechanism to create credentials, but there are more complex
mechanisms like NTLM and Negotiate that require challenge/response after
negotiation, requiring several round-trips. Add an `is_complete`
function to know when they have round-tripped enough to be a single
authentication and should now either have succeeded or failed to
authenticate.

http: examine keepalive status at message end
We cannot examine the keep-alive status of the http parser in
`http_connect`; it's too late and the critical information about whether
keep-alive is supported has been destroyed.
Per the documentation for `http_should_keep_alive`:
> If http_should_keep_alive() in the on_headers_complete or
> on_message_complete callback returns 0, then this should be
> the last message on the connection.
Query then and set the state.
