ignore: handle escaped trailing whitespace
The gitignore's pattern format specifies that "Trailing spaces
are ignored unless they are quoted with backslash ("\")". We do
not honor this currently and will treat a pattern "foo\ " as if
it was "foo\" only and a pattern "foo\ \ " as "foo\ \".
Fix our code to handle those special cases and add tests to avoid
regressions.

attr_file: refactor stripping of trailing spaces
The stripping of trailing spaces currently happens as part of
`git_attr_fnmatch__parse`. As we aren't currently parsing
trailing whitespaces correct in case they're escaped, we'll have
to change that code, though. To make actual behavioural change
easier to review, refactor the code up-front by pulling it out
into its own function that is expected to retain the exact same
functionality as before. Like this, the fix will be trivial to
apply.

online tests: use gitlab for auth failures
GitHub recently changed their behavior from returning 401s for private
or nonexistent repositories on a clone to returning 404s. For our tests
that require an auth failure (and 401), move to GitLab to request a
missing repository. This lets us continue to test our auth failure
case, at least until they decide to mimic that decision.

cache: fix cache eviction using deallocated key
When evicting cache entries, we first retrieve the object that is
to be evicted, delete the object and then finally delete the key
from the cache. In case where the cache eviction caused us to
free the cached object, though, its key will point to invalid
memory now when trying to remove it from the cache map. On my
system, this causes us to not properly remove the key from the
map, as its memory has been overwritten already and thus the key
lookup it will fail and we cannot delete it.
Fix this by only decrementing the refcount of the evictee after
we have removed it from our cache map. Add a test that caused a
segfault previous to that change.

config: validate quoted section value
When we reach a whitespace after a section name, we assume that what
will follow will be a quoted subsection name. Pass the current position
of the line being parsed to the subsection parser, so that it can
validate that subsequent characters are additional whitespace or a
single quote.
Previously we would begin parsing after the section name, looking for
the first quotation mark. This allows invalid characters to embed
themselves between the end of the section name and the first quotation
mark, eg `[section foo "subsection"]`, which is illegal.

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.

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.

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.

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.

the matching ref. E.g. if we have a ref "refs/heads/foo/bar" and
a refspec "refs/heads/*/bar:refs/remotes/origin/*/bar", we:
1. Copy over everything until hitting the glob from the <dst>
part: "refs/remotes/origin/".
2. Strip the common prefix of ref and <src> part until the glob,
which is "refs/heads/". This leaves us with a ref of "foo/bar".
3. Copy from the ref until the next "/" separator, resulting in
"refs/remotes/origin/foo".
4. Copy over the remaining part of the <dst> spec, which is
"bar": "refs/remotes/origin/foo/bar".
This worked just fine in a world where globs in refspecs were
restricted such that a globbing component may only contain a
single "*", only. But this restriction has been lifted, so that a
glob component may be nested between other characters, causing
the above algorithm to fail. Most notably the third step, where
we copy until hitting the next "/" separator, might result in a
wrong transformation. Given e.g. a ref "refs/gbranchg/head" and a
refspec "refs/g*g/head:refs/remotes/origin/*", we'd also be
copying the "g" between "branch" and "/" and end up with the
wrong transformed ref "refs/remotes/origin/branchg".
Instead of copying until the next component separator, we should
copy until we hit the pattern after the "*". So in the above
example, we'd copy until hitting the string "g/head".

refs: loosen restriction on wildcard "*" refspecs
In commit cd377f45c9 (refs: loosen restriction on wildcard "*"
refspecs, 2015-07-22) in git.git, the restrictions on wildcard
"*" refspecs has been loosened. While wildcards were previously
only allowed if the component is a single "*", this was changed
to also accept other patterns as part of the component.
We never adapted to that change and still reject any wildcard
patterns that aren't a single "*" only. Update our tests to
reflect the upstream change and adjust our own code accordingly.

rebase: orig_head and onto accessors
The rebase struct stores fields with information about the current
rebase process, which were not accessible via a public interface.
Accessors for getting the `orig_head` and `onto` branch
names and object ids have been added.

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:\`.

config_file: check result of git_array_alloc
git_array_alloc can return NULL if no memory is available, causing
a segmentation fault in memset. This adds GIT_ERROR_CHECK_ALLOC
similar to how other parts of the code base deal with the return
value of git_array_alloc.

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.

examples: use username provided via URL
The credentials callback may be passed a username in case where
the URL already includes the expected username. As we usually
cannot use a different username in such context, we should use
that one if provided and not ask the user for a diferent
username.
