regex: optionally use PCRE2
Use PCRE2 and its POSIX compatibility layer if requested by the user.
Although PCRE2 is adequate for our needs, the PCRE2 POSIX layer as
installed on Debian and Ubuntu systems is broken, so we do not opt-in to
it by default to avoid breaking users on those platforms.

regexec: use pcre as our fallback/builtin regex
Use PCRE 8.42 as the builtin regex implementation, using its POSIX
compatibility layer. PCRE uses ASCII by default and the users locale
will not influence its behavior, so its `regcomp` implementation is
similar to `regcomp_l` with a C locale.

regex: allow regex selection in cmake
Users can now select which regex implementation they want to use: one of
the system `regcomp_l`, the system PCRE, the builtin PCRE or the
system's `regcomp`.
By default the system `regcomp_l` will be used if it exists, otherwise
the system PCRE will be used. If neither of those exist, then the
builtin PCRE implementation will be used.
The system's `regcomp` is not used by default due to problems with
locales.

tests: regex: add test with LC_COLLATE being set
While we already have a test for `p_regexec` with `LC_CTYPE` being
modified, `regexec` also alters behavior as soon as `LC_COLLATE` is
being modified. Most importantly, `LC_COLLATE` changes the way how
ranges are interpreted to just not handling them at all. Thus, ensure
that either we use `regcomp_l` to avoid this, or that we've fallen back
to our builtin regex functionality which also behaves properly.

diff_driver: detect memory allocation errors when loading diff driver
When searching for a configuration key for the diff driver, we construct
the config key by modifying a buffer and then passing it to
`git_config_get_multivar_foreach`. We do not check though whether the
modification of the buffer actually succeded, so we could in theory end
up passing the OOM buffer to the config function.
Fix that by checking return codes. While at it, switch to use
`git_buf_PUTS` to avoid repetition of the appended string to calculate
its length.

cmake: fix include ordering issues with bundled deps
When linking against bundled libraries, we include their header
directories by using "-isystem". The reason for that is that we
want to handle our vendored library headers specially, most
importantly to ignore warnings generated by including them. By
using "-isystem", though, we screw up the order of searched
include directories by moving those bundled dependencies towards
the end of the lookup order. Like this, chances are high that any
other specified include directory contains a file that collides
with the actual desired include file.
Fix this by not treating the bundled dependencies' include
directories as system includes. This will move them to the front
of the lookup order and thus cause them to override
system-provided headers. While this may cause the compiler to
generate additional warnings when processing bundled headers,
this is a tradeoff we should make regardless to fix builds on
systems hitting this issue.

cmake: correctly detect if system provides `regcomp`
We assume that if we are on Win32, Amiga OS, Solaris or SunOS,
that the regcomp(3P) function cannot be provided by the system.
Thus we will in these cases always include our own, bundled regex
sources to make a regcomp implementation available. This test is
obviously very fragile, and we have seen it fail on MSYS2/MinGW
systems, which do in fact provide the regcomp symbol. The effect
is that during compilation, we will use the "regex.h" header
provided by MinGW, but use symbols provided by ourselves. This
in fact may cause subtle memory layout issues, as the structure
made available via MinGW doesn't match what our bundled code
expects.
There's one more problem with our regex detection: on the listed
platforms, we will incorrectly include the bundled regex code
even in case where the system provides regcomp_l(3), but it will
never be used for anything.
Fix the issue by improving our regcomp detection code. Instead of
relying on a fragile listing of platforms, we can just use
`CHECK_FUNCTION_EXISTS` instead. This will not in fact avoid the
header-ordering problem. But we can assume that as soon as a
system-provided "regex.h" header is provided, that
`CHECK_FUNCTION_EXISTS` will now correctly find the desired
symbol and thus not include our bundled regex code.

git_repository_init: stop traversing at windows root
Stop traversing the filesystem at the Windows directory root. We were
calculating the filesystem root for the given directory to create, and
walking up the filesystem hierarchy. We intended to stop when the
traversal path length is equal to the root path length (ie, stopping at
the root, since no path may be shorter than the root path).
However, on Windows, the root path may be specified in two different
ways, as either `Z:` or `Z:\`, where `Z:` is the current drive letter.
`git_path_dirname_r` returns the path _without_ a trailing slash, even
for the Windows root. As a result, during traversal, we need to test
that the traversal path is _less than or equal to_ the root path length
to determine if we've hit the root to ensure that we stop when our
traversal path is `Z:` and our calculated root path was `Z:\`.

util: introduce GIT_CONTAINER_OF macro
In some parts of our code, we make rather heavy use of casting
structures to their respective specialized implementation. One
example is the configuration code with the general
`git_config_backend` and the specialized `diskfile_header`
structures. At some occasions, it can get confusing though with
regards to the correct inheritance structure, which led to the
recent bug fixed in 2424e64c4 (config: harden our use of the
backend objects a bit, 2018-02-28).
Object-oriented programming in C is hard, but we can at least try
to have some checks when it comes to casting around stuff. Thus,
this commit introduces a `GIT_CONTAINER_OF` macro, which accepts
as parameters the pointer that is to be casted, the pointer it
should be cast to as well as the member inside of the target
structure that is the containing structure. This macro then tries
hard to detect mis-casts:
- It checks whether the source and target pointers are of the
same type. This requires support by the compiler, as it makes
use of the builtin `__builtin_types_compatible_p`.
- It checks whether the embedded member of the target structure
is the first member. In order to make this a compile-time
constant, the compiler-provided `__builtin_offsetof` is being
used for this.
- It ties these two checks together by the compiler-builtin
`__builtin_choose_expr`. Based on whether the previous two
checks evaluate to `true`, the compiler will either compile in
the correct cast, or it will output `(void)0`. The second case
results in a compiler error, resulting in a compile-time check
for wrong casts.
The only downside to this is that it relies heavily on
compiler-specific extensions. As both GCC and Clang support these
features, only define this macro like explained above in case
`__GNUC__` is set (Clang also defines `__GNUC__`). If the
compiler is not Clang or GCC, just go with a simple cast without
any additional checks.

ignore: treat paths with trailing "/" as directories
The function `git_ignore_path_is_ignored` is there to test the
ignore status of paths that need not necessarily exist inside of
a repository. This has the implication that for a given path, we
cannot always decide whether it references a directory or a file,
and we need to distinguish those cases because ignore rules may
treat those differently. E.g. given the following gitignore file:
*
!/**/
we'd only want to unignore directories, while keeping files
ignored. But still, calling `git_ignore_path_is_ignored("dir/")`
will say that this directory is ignored because it treats "dir/"
as a file path.
As said, the `is_ignored` function cannot always decide whether
the given path is a file or directory, and thus it may produce
wrong results in some cases. While this is unfixable in the
general case, we can do better when we are being passed a path
name with a trailing path separator (e.g. "dir/") and always
treat them as directories.

patch_parse: fix parsing addition/deletion of file with space
The diff header format is a strange beast in that it is inherently
unparseable in an unambiguous way. While parsing
a/file.txt b/file.txt
is obvious and trivially doable, parsing a diff header of
a/file b/file ab.txt b/file b/file ab.txt
is not (but in fact valid and created by git.git).
Due to that, we have relaxed our diff header parser in commit 80226b5f6
(patch_parse: allow parsing ambiguous patch headers, 2017-09-22), so
that we started to bail out when seeing diff headers with spaces in
their file names. Instead, we try to use the "---" and "+++" lines,
which are unambiguous.
In some cases, though, we neither have a useable file name from the
header nor from the "---" or "+++" lines. This is the case when we have
a deletion or addition of a file with spaces: the header is unparseable
and the other lines will simply show "/dev/null". This trips our parsing
logic when we try to extract the prefix (the "a/" part) that is being
used in the path line, where we unconditionally try to dereference a
NULL pointer in such a scenario.
We can fix this by simply not trying to parse the prefix in cases where
we have no useable path name. That'd leave the parsed patch without
either `old_prefix` or `new_prefix` populated. But in fact such cases
are already handled by users of the patch object, which simply opt to
use the default prefixes in that case.

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.

Each hash implementation should define `git_hash_global_init`
This means the forward declaration isn't necessary. The forward
declaration can cause compilation errors as it conflicts with the
`GIT_INLINE` declaration (the signatures are different).

ignore: Do not match on prefix of negated patterns
Matching on the prefix of a negated pattern was triggering false
negatives on siblings of that pattern. e.g.
Given the .gitignore:
dir/*
!dir/sub1/sub2/**
The path `dir/a.text` would not be ignored.

odb: provide a free function for custom backends
Custom backends can allocate memory when reading objects and providing
them to libgit2. However, if an error occurs in the custom backend
after the memory has been allocated for the custom object but before
it's returned to libgit2, the custom backend has no way to free that
memory and it must be leaked.
Provide a free function that corresponds to the alloc function so that
custom backends have an opportunity to free memory before they return an
error.

odb: rename git_odb_backend_malloc for consistency
The `git_odb_backend_malloc` name is a system function that is provided
for custom ODB backends and allows them to allocate memory for an ODB
object in the read callback. This is important so that libgit2 can
later free the memory used by an ODB object that was read from the
custom backend.
However, the name _suggests_ that it actually allocates a
`git_odb_backend`. It does not; rename it to make it clear that it
actually allocates backend _data_.

p_fallocate: compatibility fixes for macOS
On macOS, fcntl(..., F_PREALLOCATE, ...) will only succeed when followed
by an ftruncate(), even when it reports success.
However, that syscall will fail when the file already exists. Thus, we
must ignore the error code and simply let ftruncate extend the size of
the file itself (albeit slowly).
By calling ftruncate, we also need to prevent against file shrinkage,
for compatibility with posix_ftruncate, which will only extend files,
never shrink them.
