tests: config: verify that the global config is actually readable
While we do verify that we are able to open the global ".gitconfig" file
in config::global::open_global, we never verify that we it is in fact
readable. Do so by writing the global configuration file and verifying
that reading from it produces the expected values.

tests: config: make sure to clean up after each test
The config::global test suite creates various different directories and
files which are being populated with pretend-global files.
Unfortunately, the tests do not clean up after themselves, which may
cause subsequent tests to fail due to cruft left behind.
Fix this by always removing created directories and their contents.

tests: apply: verify that we correctly truncate the source buffer
Previously, we would fail to correctly truncate the source buffer
if the source has more than one line and ends with a non-newline
character. In the following call, we thus truncate the source
string in the middle of the second line. Without the bug fixed,
we would successfully apply the patch to the source and return
success. With the overflow being fixed, we should return an
error now.

oidmap: introduce high-level setter for key/value pairs
Currently, one would use either `git_oidmap_insert` to insert key/value pairs
into a map or `git_oidmap_put` to insert a key only. These function have
historically been macros, which is why their syntax is kind of weird: instead of
returning an error code directly, they instead have to be passed a pointer to
where the return value shall be stored. This does not match libgit2's common
idiom of directly returning error codes.Furthermore, `git_oidmap_put` is tightly
coupled with implementation details of the map as it exposes the index of
inserted entries.
Introduce a new function `git_oidmap_set`, which takes as parameters the map,
key and value and directly returns an error code. Convert all trivial callers of
`git_oidmap_insert` and `git_oidmap_put` to make use of it.

oidmap: introduce high-level getter for values
The current way of looking up an entry from a map is tightly coupled with the
map implementation, as one first has to look up the index of the key and then
retrieve the associated value by using the index. As a caller, you usually do
not care about any indices at all, though, so this is more complicated than
really necessary. Furthermore, it invites for errors to happen if the correct
error checking sequence is not being followed.
Introduce a new high-level function `git_oidmap_get` that takes a map and a key
and returns a pointer to the associated value if such a key exists. Otherwise,
a `NULL` pointer is returned. Adjust all callers that can trivially be
converted.

maps: provide a uniform entry count interface
There currently exist two different function names for getting the entry count
of maps, where offmaps offset and string maps use `num_entries` and OID maps use
`size`. In most programming languages with built-in map types, this is simply
called `size`, which is also shorter to type. Thus, this commit renames the
other two functions `num_entries` to match the common way and adjusts all
callers.

maps: use uniform lifecycle management functions
Currently, the lifecycle functions for maps (allocation, deallocation, resize)
are not named in a uniform way and do not have a uniform function signature.
Rename the functions to fix that, and stick to libgit2's naming scheme of saying
`git_foo_new`. This results in the following new interface for allocation:
- `int git_<t>map_new(git_<t>map **out)` to allocate a new map, returning an
error code if we ran out of memory
- `void git_<t>map_free(git_<t>map *map)` to free a map
- `void git_<t>map_clear(git<t>map *map)` to remove all entries from a map
This commit also fixes all existing callers.

maps: provide high-level iteration interface
Currently, our headers need to leak some implementation details of maps due to
their direct use of indices in the implementation of their foreach macros. This
makes it impossible to completely hide the map structures away, and also makes
it impossible to include the khash implementation header in the C files of the
respective map only.
This is now being fixed by providing a high-level iteration interface
`map_iterate`, which takes as inputs the map that shall be iterated over, an
iterator as well as the locations where keys and values shall be put into. For
simplicity's sake, the iterator is a simple `size_t` that shall initialized to
`0` on the first call. All existing foreach macros are then adjusted to make use
of this new function.

branch: fix `branch_is_checked_out` with bare repos
In a bare repository, HEAD usually points to the branch that is
considered the "default" branch. As the current implementation for
`git_branch_is_checked_out` only does a comparison of HEAD with the
branch that is to be checked, it will say that the branch pointed to by
HEAD in such a bare repo is checked out.
Fix this by skipping the main repo's HEAD when it is bare.

branches: introduce flag to skip enumeration of certain HEADs

cases, it might be required to skip either of those, though. Add a flag
in preparation for the following commit that enables this behaviour.

branches: do not assert that the given ref is a branch
Libraries should use assert(3P) only very scarcely. First, we usually
shouldn't cause the caller of our library to abort in case where the
assert fails. Second, if code is compiled with -DNDEBUG, then the assert
will not be included at all.
In our `git_branch_is_checked_out` function, we have an assert that
verifies that the given reference parameter is non-NULL and in fact a
branch. While the first check is fine, the second is not. E.g. when
compiled with -DNDEBUG, we'd proceed and treat the given reference as a
branch in all cases.
Fix the issue by instead treating a non-branch reference as not being
checked out. This is the obvious solution, as references other than
branches cannot be directly checked out.

deprecation: ensure we GIT_EXTERN deprecated funcs
Although the error functions were deprecated, we did not properly mark
them as deprecated. We need to include the `deprecated.h` file in order
to ensure that the functions get their export attributes.
Similarly, do not define `GIT_DEPRECATE_HARD` within the library, or
those functions will also not get their export attributes. Define that
only on the tests and examples.

Some more warnings were gleaned from the Windows build, but I stopped
when I saw that some third-party dependencies (e.g. zlib) have warnings
of their own, so we might never be able to enable -Werror there.

which takes a registration structure and a TLS boolean. This allows
callers to register non-TLS streams as well as TLS streams.
Provide `git_stream_register_tls` that takes just the init callback for
backward compatibliity.

tests: optionally ignore https cert validation
For testing, we may wish to use a man-in-the-middle proxy that can
inspect the CONNECT traffic to our test endpoints. For this, we will
need to accept the proxy's certificate, which will not be valid for the
true endpoint.
Add a new environment variable, GITTEST_REMOTE_SSL_NOVERIFY to disable
https certificate validation for the tests.

tls: introduce a wrap function
Introduce `git_tls_stream_wrap` which will take an existing `stream`
with an already connected socket and begin speaking TLS on top of it.
This is useful if you've built a connection to a proxy server and you
wish to begin CONNECT over it to tunnel a TLS connection.
Also update the pluggable TLS stream layer so that it can accept a
registration structure that provides an `init` and `wrap` function,
instead of a single initialization function.

proxy tests: support self-signed proxy cert
Give the proxy tests a proxy certificate callback, and allow self-signed
certificates when the `GITTEST_REMOTE_PROXY_SELFSIGNED` environment
variable is set (to anything). In that case, simply compare the hostname
from the callback to the hostname that we connected to.

tests: support optional PROXY_SCHEME
As we want to support HTTPS proxies, support an optional
`GITTEST_REMOTE_PROXY_SCHEME` environment variable for tests that will
allow for HTTPS support. (When unset, the tests default to HTTP
proxies.)

tests: PROXY_URL is more accurately PROXY_HOST
Change the `GITTEST_REMOTE_PROXY_URL` environment variable to be
`GITTEST_REMOTE_PROXY_HOST`, since it is a host:port combination, not an
actual URL. (We cannot use a URL here since we may want to include the
username:password combination in the constructed URL.)

tests: mailmap: avoid definition of unused static variables
The mailmap testdata header contains a set of static variable
definitions. As these variables aren't used in all places where they are
used, they trigger the unused-const-variable warnings. As we have
currently disabled those warnings explicitly, they are never triggered,
but we intend to enable them.
Avoid the issue by only keeping variable definitions that are actually
used in all locations. Move the others to where they are used.

khash: remove intricate knowledge of khash types
Instead of using the `khiter_t`, `git_strmap_iter` and `khint_t` types,
simply use `size_t` instead. This decouples code from the khash stuff
and makes it possible to move the khash includes into the implementation
files.

tests: path: only compile test_canonicalize on Win32 platforms
The function `test_canonicalize` is only used on Win32 platforms. It will thus
result in an unused function warning if these warnings are enabled and one is on
a platform different than Win32.
Fix the issue by only compiling in the function on Win32 platforms.

tests: move apply_helpers functions into own compilation unit
Currently, the "apply_helper" functions used for testing the apply logic are all
statically defined in the "apply_helpers.h" header file. This may lead to
warnings from the compiler in case where this header file is included, but not
all functions it brings along are used in the compilation unit where it has been
included into.
Fix these potential warnings by moving the implementation into its own
compilation unit "apply_helpers.c".

config: fix adding files if their parent directory is a file
When we try to add a configuration file with `git_config_add_file_ondisk`, we
treat nonexisting files as empty. We do this by performing a stat call, ignoring
ENOENT errors. This works just fine in case the file or any of its parents
simply does not exist, but there is also the case where any of the parent
directories is not a directory, but a file. So e.g. trying to add a
configuration file "/dev/null/.gitconfig" will fail, as `errno` will be ENOTDIR
instead of ENOENT.
Catch ENOTDIR in addition to ENOENT to fix the issue. Add a test that verifies
we are able to add configuration files with such an invalid path file just fine.

refs: add support for core.logAllRefUpdates=always
Since we were not expecting this config entry to contain a string, we
would fail as soon as its (cached) value would be accessed. Hence,
provide some constants for the 4 states we use, and account for "always"
when we decide to reflog changes.

strntol: fix out-of-bounds reads when parsing numbers with leading sign
When parsing a number, we accept a leading plus or minus sign to return
a positive or negative number. When the parsed string has such a leading
sign, we set up a flag indicating that the number is negative and
advance the pointer to the next character in that string. This misses
updating the number of bytes in the string, though, which is why the
parser may later on do an out-of-bounds read.
Fix the issue by correctly updating both the pointer and the number of
remaining bytes. Furthermore, we need to check whether we actually have
any bytes left after having advanced the pointer, as otherwise the
auto-detection of the base may do an out-of-bonuds access. Add a test
that detects the out-of-bound read.
Note that this is not actually security critical. While there are a lot
of places where the function is called, all of these places are guarded
or irrelevant:
- commit list: this operates on objects from the ODB, which are always
NUL terminated any may thus not trigger the off-by-one OOB read.
- config: the configuration is NUL terminated.
- curl stream: user input is being parsed that is always NUL terminated
- index: the index is read via `git_futils_readbuffer`, which always NUL
terminates it.
- loose objects: used to parse the length from the object's header. As
we check previously that the buffer contains a NUL byte, this is safe.
- rebase: this parses numbers from the rebase instruction sheet. As the
rebase code uses `git_futils_readbuffer`, the buffer is always NUL
terminated.
- revparse: this parses a user provided buffer that is NUL terminated.
- signature: this parser the header information of objects. As objects
read from the ODB are always NUL terminated, this is a non-issue. The
constructor `git_signature_from_buffer` does not accept a length
parameter for the buffer, so the buffer needs to be NUL terminated, as
well.
- smart transport: the buffer that is parsed is NUL terminated
- tree cache: this parses the tree cache from the index extension. The
index itself is read via `git_futils_readbuffer`, which always NUL
terminates it.
- winhttp transport: user input is being parsed that is always NUL
terminated

tests: apply: fix reference to deprecated `git_buf_free`
Since commit 56ffdfc61 (buffer: deprecate `git_buf_free` in favor of
`git_buf_dispose`, 2018-02-08), the function `git_buf_free` is
deprecated and shall not be used anymore. As part of the new apply
framework that has been cooking for quite some time some new references
have been introduced to that deprecated function. Replace them with
calls to `git_buf_dispose`.
