ci: fix location of fuzzer corpora on VSTS
When using VSTS-based builds, we are in a different location than when
doing Travis builds. Due to this, the relative path to our fuzzer
corpora does not work on VSTS. Fix it by using `${SOURCE_DIR}` instead.

fuzzers: limit maximum pack object count
By default, libgit2 allows up to 2^32 objects when downloading a
packfile from a remote. For each of these objects, libgit2 will allocate
up to two small structs, which in total adds up to quite a lot of
memory. As a result, our fuzzers might run out of memory rather quick in
case where they receive as input a packfile with such a huge count of
objects.
Limit the packfile object count to 10M objects. This is sufficiently big
to still work with most largish repos (linux.git has around 6M objects
as of now), but small enough to not cause the fuzzer to OOM.

fuzzers: import download_refs fuzzer from oss-fuzz
This is a direct copy of the code from google/oss-fuzz, written by
Nelson Elhage (@nelhage). Note that due to the ".cc" ending, the file
will not yet be picked up by the build system. This is intended, as
currently that file is partly written in C++, requiring a conversion to
C.

cmake: remove need to add "-fsanitize=fuzzer" flag for fuzzers
Right now, users are being instrucded to add the
"-DCMAKE_EXE_LINKER_FLAGS=-fsanitize=fuzzer" flag when they want to
build our fuzzers. This is error-prone and user unfriendly. Instead,
just add the flag to our fuzzers' build instructions so that it happens
automatically. Adjust the README accordingly.

cmake: error out if required C flags are not supported
We do want to notify users compiling our source code early on if they
try to use C flags which aren't supported. Add a new macro `AddCFlag`,
which results in a fatal error in case the flag is not supported, and
use it for our fuzzing flags.

fuzzers: avoid use of libgit2 internals in packfile_raw
The packfile_raw fuzzer is using some internal APIs from libgit2, which
makes it hard to compile it as part of the oss-fuzz project. As oss-fuzz
requires us to link against the C++ FuzzingEngine library, we cannot use
"-DBUILD_FUZZERS=ON" directly but instead have to first compile an
object from our fuzzers and then link against the C++ library. Compiling
the fuzzer objects thus requires an external invocation of CC, and we
certainly don't want to do further black magic by adding libgit2's
private source directory to the header include path.
To fix the issue, convert the code to not use any internal APIs. Besides
some headers which we have to add now, this also requires us to change
to the hashing function of the ODB. Note that this will change the
hashing result, as we have previously not prepended the object header to
the data that is to be hashed. But this shouldn't matter in practice, as
we don't care for the hash value anyway.

cmake: remove USE_SANITIZER and USE_COVERAGE options
Both the USE_SANITIZER and USE_COVERAGE options are convenience options
that turn on a set of CFLAGS. Despite our own set of CFLAGS required to
build libgit2, we have no real business to mess with them, though, as
they can easily be passed in by the user via specifying the CFLAGS
environment variable. The reasoning behind not providing them is that as
soon as we start adding those for some usecases, users might ask for
other sets of CFLAGS catering to their specific need in another usecase.
Thus, we do not want to support them here.

fuzzers: rename "fuzz" directory to match our style
Our layout uses names like "examples" or "tests" which is why the "fuzz"
directory doesn't really fit in here. Rename the directory to be called
"fuzzers" instead. Furthermore, we rename the fuzzer "fuzz_packfile_raw"
to "packfile_raw_fuzzer", which is also in line with the already
existing fuzzer at google/oss-fuzz.
While at it, rename the "packfile_raw" fuzzer to instead just be called
"packfile" fuzzer.

buf tests: allocate a smaller size for the oom
On Linux (where we run valgrind) allocate a smaller buffer, but still an
insanely large size. This will cause malloc to fail but will not cause
valgrind to report a likely error with a negative-sized malloc.
Keep the original buffer size on non-Linux platforms: this is
well-tested on them and changing it may be problematic. On macOS, for
example, using the new size causes `malloc` to print a warning to
stderr.

mbedtls: remove unused variable "cacert"
In commit 382ed1e87 (mbedtls: load default CA certificates, 2018-03-29),
the function `git_mbedtls_stream_global_init` was refactored to call out
to `git_mbedtls__set_cert_location` instead of setting up the
certificates itself. The conversion forgot to remove the now-unused
"cacert" variable, which is now only getting declared to be free'd at
the end of the function. Remove it.

ignore: improve `git_ignore_path_is_ignored` description Git analogy
In attempt to provide adequate Git command analogy in regards to
ignored files handling, `git_ignore_path_is_ignored` description
mentions doing `git add .` on directory containing the file, and
whether the file in question would be added or not - but behavior of
the two matches for untracked files only, making the comparison
misleading in general sense.
For tracked files, Git doesn't subject them to ignore rules, so even
if a rule applies, `git add .` would actually add the tracked file
changes to index, while `git_ignore_path_is_ignored` would still
consider the file being ignored (as it doesn't check the index, as
documented).
Let's provide `git check-ignore --no-index` as analogous Git command
example instead, being more aligned with what `git_ignore_path_is_ignored`
is about, no matter if the file in question is already tracked or not.
See issue #4720 (git_ignore_path_is_ignored documentation
misleading?, 2018-07-10)[1] for additional information.

cmake: enforce C90 standard
While the aim of libgit2 was to conform to C90 code, we never instructed
the compiler to enforce C90 compliance. Thus, quite a few violations
were able to get into our code base, which have been removed with the
previous commits. As we are now able to build libgit2 with C90 enforced,
we can set the C_STANDARD property for our own build targets.
Note that we explicitly avoid setting the C standard for our third-party
dependencies. At least the zlib target does not build with C90 enforced,
and we do not want to fix them by deviating from upstream. Thus we
simply enforce no standard for them.

mbedtls: fix `inline` being used in mbedtls headers
The mbedtls headers make direct use of the `inline` attribute to
instruct the compiler to inline functions. As this function is not C90
compliant, this can cause the compiler to error as soon as any of these
files is included and the `-std=c90` flag is being added.
The mbedtls headers declaring functions as inline always have a prelude
which define `inline` as a macro in case it is not yet defined. Thus, we
can easily replace their define with our own define, which simply copies
the logic of our own `GIT_INLINE` macro.

cmake: distinguish internal and system include directories
While we want to enforce strict C90 mode, this may cause issues with
system provided header files which are themselves not strictly
conforming. E.g. if a system header has C++ style comments, a compiler
in strict C90 mode would produce an error and abort the build. As the
user most likely doesn't want to change the system header, this would
completely break the build on such systems. One example of this is
mbedtls, which provides such header files.
The problem can be worked around by distinguishing between
system-provided and project-provided include directories. When adding
include directories via "-isystem" instead of "-I", the compiler will
skip certain checks and print out less warnings. To use system includes,
we can simply add the "SYSTEM" flag to CMake's `INCLUDE_DIRECTORIES` and
`TARGET_INCLUDE_DIRECTORIES` functions. Note that we have to split the
include directories into two variables because of this, as we definitely
still want to check for all warnings produced by our own header files.

treewide: remove use of C++ style comments
C++ style comment ("//") are not specified by the ISO C90 standard and
thus do not conform to it. While libgit2 aims to conform to C90, we did
not enforce it until now, which is why quite a lot of these
non-conforming comments have snuck into our codebase. Do a tree-wide
conversion of all C++ style comments to the supported C style comments
to allow us enforcing strict C90 compliance in a later commit.

treewide: avoid use of `inline` attribute
ISO C90 does not specify the `inline` attribute, and as such we cannot
use it in our code. While we already use `__inline` when building in
Microsoft Visual Studio, we should also be using the `__inline__`
attribute from GCC/Clang. Otherwise, if we're using neither MSVC nor
GCC/Clang, we should simply avoid using `inline` at all and just define
functions as static.
This commit adjusts our own `GIT_INLINE` macro as well as the inline
macros specified by khash and xdiff. This allows us to enable strict C90
mode in a later commit.

annotated_commit: make the refname accessible
As git_annotated_commit seems to behave like cgit's refish, it's quite
helpful to abstract away "targets" via git_annotated_commit_from_id/from_ref.
As the former is accessible via git_annotated_commit_id, make the latter
also available to users.

tests: fix a relative pathname issue
The path given to `git_index_add_bypath` is relative to the root of the
repository. That `describe/file` path is relative to the root of the
sandbox directory, hence if I add the missing `cl_git_pass` I rightfully
get an error that `$SANDBOX/describe/describe/file doesn't exist`.
The path is thus changed to be made relative to the repository, which
makes the failure go away and "restore" the test.

smart: don't dereference a NULL pkt pointer
By clarifying what detect_caps returns on empty/missing packet, we can
be sure there are actually refs to process. The old code could blindly
dereference `first`, which might have been NULL.

streams: report OpenSSL errors if global init fails
In case when the global initialization of the OpenSSL stream fails, the
user is left without any hint as to what went wrong as we do not provide
any error message at all. This commit refactors the init function to
have a common error path, which now also sets an error message including
the error string provided by OpenSSL.
