patch_parse: use paths from "---"/"+++" lines for binary patches
For some patches, it is not possible to derive the old and new file
paths from the patch header's first line, most importantly when they
contain spaces. In such a case, we derive both paths from the "---" and
"+++" lines, which allow for non-ambiguous parsing. We fail to use these
paths when parsing binary patches without data, though, as we always
expect the header paths to be filled in.
Fix this by using the "---"/"+++" paths by default and only fall back to
header paths if they aren't set. If neither of those paths are set, we
just return an error. Add two tests to verify this behaviour, one of
which would have previously caused a segfault.

Similar as in commit dadbb33b6 (Fix crash if snapshotting a

configuration entries. As this deletes more code than it adds, it
doesn't make any sense to not allow for this and allows users to treat
config backends mostly the same.

patch_parse: fix segfault when header path contains whitespace only
When parsing header paths from a patch, we reject any patches with empty
paths as malformed patches. We perform the check whether a path is empty
before sanitizing it, though, which may lead to a path becoming empty
after the check, e.g. if we have trimmed whitespace. This may lead to a
segfault later when any part of our patching logic actually references
such a path, which may then be a `NULL` pointer.
Fix the issue by performing the check after sanitizing. Add tests to
catch the issue as they would have produced a segfault previosuly.

config_file: keep reference to config entries when creating iterator
When creating a configuration file iterator, then we first refresh the
backend and then afterwards duplicate all refreshed configuration
entries into the iterator in order to avoid seeing any concurrent
modifications of the entries while iterating. The duplication of entries
is not guarded, though, as we do not increase the refcount of the
entries that we duplicate right now. This opens us up for a race, as
another thread may concurrently refresh the repository configuration and
thus swap out the current set of entries. As we didn't increase the
refcount, this may lead to the entries being free'd while we iterate
over them in the first thread.
Fix the issue by properly handling the lifecycle of the backend's
entries via `config_file_entries_take` and `git_config_entries_free`,
respectively.

config_file: refactor taking entries ref to return an error code
The function to take a reference to the config file's config entries
currently returns the reference via return value. Due to this, it's
harder than necessary to integrate into our typical coding style, as one
needs to make sure that a proper error code is set before erroring out
from the caller. This bites us in `config_file_delete`, where we call
`goto out` directly when `config_file_entries_take` returns `NULL`, but
we actually forget to set up the error code and thus return success.
Fix the issue by refactoring the function to return an error code and
pass the reference via an out-pointer.

patch_parse: detect overflow when calculating old/new line position
When the patch contains lines close to INT_MAX, then it may happen that
we end up with an integer overflow when calculating the line of the
current diff hunk. Reject such patches as unreasonable to avoid the
integer overflow.
As the calculation is performed on integers, we introduce two new
helpers `git__add_int_overflow` and `git__sub_int_overflow` that perform
the integer overflow check in a generic way.

patch_parse: fix out-of-bounds read with No-NL lines
We've got two locations where we copy lines into the patch. The first
one is when copying normal " ", "-" or "+" lines, while the second
location gets executed when we copy "\ No newline at end of file" lines.
While the first one correctly uses `git__strndup` to copy only until the
newline, the other one doesn't. Thus, if the line occurs at the end of
the patch and if there is no terminating NUL character, then it may
result in an out-of-bounds read.
Fix the issue by using `git__strndup`, as was already done in the other
location. Furthermore, add allocation checks to both locations to detect
out-of-memory situations.

patch_parse: reject empty path names
When parsing patch headers, we currently accept empty path names just
fine, e.g. a line "--- \n" would be parsed as the empty filename. This
is not a valid patch format and may cause `NULL` pointer accesses at a
later place as `git_buf_detach` will return `NULL` in that case.
Reject such patches as malformed with a nice error message.

patch_parse: reject patches with multiple old/new paths
It's currently possible to have patches with multiple old path name
headers. As we didn't check for this case, this resulted in a memory
leak when overwriting the old old path with the new old path because we
simply discarded the old pointer.
Instead of fixing this by free'ing the old pointer, we should reject
such patches altogether. It doesn't make any sense for the "---" or
"+++" markers to occur multiple times within a patch n the first place.
This also implicitly fixes the memory leak.

refdb_fs: properly parse corrupted reflogs
In previous versions, libgit2 could be coerced into writing reflog
messages with embedded newlines into the reflog by using
`git_stash_save` with a message containing newlines. While the root
cause is fixed now, it was noticed that upstream git is in fact able to
read such corrupted reflog messages just fine.
Make the reflog parser more lenient in order to just skip over
malformatted reflog lines to bring us in line with git. This requires us
to change an existing test that verified that we do indeed _fail_ to
parse such logs.

reflog: allow adding entries with newlines in their message
Currently, the reflog disallows any entries that have a message with
newlines, as that would effectively break the reflog format, which may
contain a single line per entry, only. Upstream git behaves a bit
differently, though, especially when considering stashes: instead of
rejecting any reflog entry with newlines, git will simply replace
newlines with spaces. E.g. executing 'git stash push -m "foo\nbar"' will
create a reflog entry with "foo bar" as entry message.
This commit adjusts our own logic to stop rejecting commit messages with
newlines. Previously, this logic was part of `git_reflog_append`, only.
There is a second place though where we add reflog entries, which is the
serialization code in the filesystem refdb. As it didn't contain any
sanity checks whatsoever, the refdb would have been perfectly happy to
write malformatted reflog entries to the disk. This is being fixed with
the same logic as for the reflog itself.

refs: unlock unmodified refs on transaction commit
Refs which are locked in a transaction without an altered target,
still should to be unlocked on `git_transaction_commit`.
`git_transaction_free` also unlocks refs but the moment of calling of `git_transaction_free`
cannot be controlled in all situations.
Some binding libs call `git_transaction_free` on garbage collection or not at all if the
application exits before and don't provide public access to `git_transaction_free`.
It is better to release locks as soon as possible.

refs: fix locks getting forcibly removed
The flag GIT_FILEBUF_FORCE currently does two things:
1. It will cause the filebuf to create non-existing leading
directories for the file that is about to be written.
2. It will forcibly remove any pre-existing locks.
While most call sites actually do want (1), they do not want to
remove pre-existing locks, as that renders the locking mechanisms
effectively useless.
Introduce a new flag `GIT_FILEBUF_CREATE_LEADING_DIRS` to
separate both behaviours cleanly from each other and convert
callers to use it instead of `GIT_FILEBUF_FORCE` to have them
honor locked files correctly.
As this conversion removes all current users of `GIT_FILEBUF_FORCE`,
this commit removes the flag altogether.

cmake: update minimum CMake version to v3.5.1
Back in commit cf9f34521 (cmake: bump minimum version to 2.8.11,
2017-09-06), we have bumped the minimum CMake version to require at
least v2.8.11. The main hold-backs back then were distributions like
RHEL/CentOS as well as Ubuntu Trusty, which caused us to not target a
more modern version. Nowadays, Ubuntu Trusty has been EOL'd and CentOS 6
has CMake v3.6.1 available via the EPEL6 repository, and thus it seems
fair to upgrade to a more recent version.
Going through repology [1], one can see that all supported mainstream
distributions do in fact have CMake 3 available. Going through the list,
the minimum version that is supported by all mainstream distros is in
fact v3.5.1:
- CentOS 6 via EPEL6: 3.6.1
- Debian Oldstable: 3.7.2
- Fedora 26: 3.8.2
- OpenMandriva 3.x: 3.5.1
- Slackware 14.2: 3.5.2
- Ubuntu 16.04: 3.5.1
Consequentally, let's upgrade CMake to the minimum version of 3.5.1 and
remove all the version CMake checks that aren't required anymore.

commit_list: store in/out-degrees as uint16_t
The commit list's in- and out-degrees are currently stored as `unsigned
short`. When assigning it the value of `git_array_size`, which returns
an `size_t`, this generates a warning on some Win32 platforms due to
loosing precision.
We could just cast the returned value of `git_array_size`, which would
work fine for 99.99% of all cases as commits typically have less than
2^16 parents. For crafted commits though we might end up with a wrong
value, and thus we should definitely check whether the array size
actually fits into the field.
To ease the check, let's convert the fields to store the degrees as
`uint16_t`. We shouldn't rely on such unspecific types anyway, as it may
lead to different behaviour across platforms. Furthermore, this commit
introduces a new `git__is_uint16` function to check whether it actually
fits -- if not, we return an error.

regexp: implement new regular expression API
We currently support a set of different regular expression backends with
PCRE, PCRE2, regcomp(3P) and regcomp_l(3). The current implementation of
this is done via a simple POSIX wrapper that either directly uses
supplied functions or that is a very small wrapper.
To support PCRE and PCRE2, we use their provided <pcreposix.h> and
<pcre2posix.h> wrappers. These wrappers are implemented in such a way
that the accompanying libraries pcre-posix and pcre2-posix provide the
same symbols as the libc ones, namely regcomp(3P) et al. This works out
on some systems just fine, most importantly on glibc-based ones, where
the regular expression functions are implemented as weak aliases and
thus get overridden by linking in the pcre{,2}-posix library. On other
systems we depend on the linking order of libc and pcre library, and as
libc always comes first we will end up with the functions of the libc
implementation. As a result, we may use the structures `regex_t` and
`regmatch_t` declared by <pcre{,2}posix.h>, but use functions defined by
the libc, leading to segfaults.
The issue is not easily solvable. Somed distributions like Debian have
resolved this by patching PCRE and PCRE2 to carry custom prefixes to all
the POSIX function wrappers. But this is not supported by upstream and
thus inherently unportable between distributions. We could instead try
to modify linking order, but this starts becoming fragile and will not
work e.g. when libgit2 is loaded via dlopen(3P) or similar ways. In the
end, this means that we simply cannot use the POSIX wrappers provided by
the PCRE libraries at all.
Thus, this commit introduces a new regular expression API. The new API
is on a tad higher level than the previous POSIX abstraction layer, as
it tries to abstract away any non-portable flags like e.g. REG_EXTENDED,
which has no equivalents in all of our supported backends. As there are
no users of POSIX regular expressions that do _not_ reguest REG_EXTENDED
this is fine to be abstracted away, though. Due to the API being
higher-level than before, it should generally be a tad easier to use
than the previous one.
Note: ideally, the new API would've been called `git_regex_foobar` with
a file "regex.h" and "regex.c". Unfortunately, this is currently
impossible to implement due to naming clashes between the then-existing
"regex.h" and <regex.h> provided by the libc. As we add the source
directory of libgit2 to the header search path, an include of <regex.h>
would always find our own "regex.h". Thus, we have to take the bitter
pill of adding one more character to all the functions to disambiguate
the includes.
To improve guarantees around cross-backend compatibility, this commit
also brings along an improved regular expression test suite
core::regexp.

buffer: fix printing into out-of-memory buffer
Before printing into a `git_buf` structure, we always call `ENSURE_SIZE`
first. This macro will reallocate the buffer as-needed depending on
whether the current amount of allocated bytes is sufficient or not. If
`asize` is big enough, then it will just do nothing, otherwise it will
call out to `git_buf_try_grow`. But in fact, it is insufficient to only
check `asize`.
When we fail to allocate any more bytes e.g. via `git_buf_try_grow`,
then we set the buffer's pointer to `git_buf__oom`. Note that we touch
neither `asize` nor `size`. So if we just check `asize > targetsize`,
then we will happily let the caller of `ENSURE_SIZE` proceed with an
out-of-memory buffer. As a result, we will print all bytes into the
out-of-memory buffer instead, resulting in an out-of-bounds write.
Fix the issue by having `ENSURE_SIZE` verify that the buffer is not
marked as OOM. Add a test to verify that we're not writing into the OOM
buffer.

buffer: fix infinite loop when growing buffers
When growing buffers, we repeatedly multiply the currently allocated
number of bytes by 1.5 until it exceeds the requested number of bytes.
This has two major problems:
1. If the current number of bytes is tiny and one wishes to resize
to a comparatively huge number of bytes, then we may need to loop
thousands of times.
2. If resizing to a value close to `SIZE_MAX` (which would fail
anyway), then we probably hit an infinite loop as multiplying the
current amount of bytes will repeatedly result in integer
overflows.
When reallocating buffers, one typically chooses values close to 1.5 to
enable re-use of resulting memory holes in later reallocations. But
because of this, it really only makes sense to use a factor of 1.5
_once_, but not looping until we finally are able to fit it. Thus, we
can completely avoid the loop and just opt for the much simpler
algorithm of multiplying with 1.5 once and, if the result doesn't fit,
just use the target size. This avoids both problems of looping
extensively and hitting overflows.
This commit also adds a test that would've previously resulted in an
infinite loop.

buffer: fix memory leak if unable to grow buffer
If growing a buffer fails, we set its pointer to the static
`git_buf__oom` structure. While we correctly free the old pointer if
`git__malloc` returned an error, we do not free it if there was an
integer overflow while calculating the new allocation size. Fix this
issue by freeing the pointer to plug the memory leak.

ignore: correct handling of nested rules overriding wild card unignore
problem:
filesystem_iterator loads .gitignore files in top-down order.
subsequently, ignore module evaluates them in the order they are loaded.
this creates a problem if we have unignored a rule (using a wild card)
in a sub dir and ignored it again in a level further below (see the test
included in this patch).
solution:
process ignores in reverse order.

iterator: avoid leaving partially initialized frame on stack
When allocating tree iterator entries, we use GIT_ERROR_ALLOC_CHECK` to
check whether the allocation has failed. The macro will cause the
function to immediately return, though, leaving behind a partially
initialized iterator frame.
Fix the issue by manually checking for memory allocation errors and
using `goto done` in case of an error, popping the iterator frame.

diff_generate: detect memory allocation errors when preparing opts
When preparing options for the two iterators that are about to be
diffed, we allocate a common prefix for both iterators depending on
the options passed by the user. We do not check whether the allocation
was successful, though. In fact, this isn't much of a problem, as using
a `NULL` prefix is perfectly fine. But in the end, we probably want to
detect that the system doesn't have any memory left, as we're unlikely
to be able to continue afterwards anyway.
While the issue is being fixed in the newly created function
`diff_prepare_iterator_opts`, it has been previously existing in the
previous macro `DIFF_FROM_ITERATORS` already.

diff_generate: refactor `DIFF_FROM_ITERATORS` macro of doom
While the `DIFF_FROM_ITERATORS` does make it shorter to implement the
various `git_diff_foo_to_bar` functions, it is a complex and unreadable
beast that implicitly assumes certain local variable names. This is not
something desirable to have at all and obstructs understanding and more
importantly debugging the code by quite a bit.
The `DIFF_FROM_ITERATORS` macro basically removed the burden of having
to derive the options for both iterators from a pair of iterator flags
and the diff options. This patch introduces a new function that does the
that exact and refactors all callers to manage the iterators by
themselves.
As we potentially need to allocate a shared prefix for the
iterator, we need to tell the caller to allocate that prefix as soon as
the options aren't required anymore. Thus, the function has a `char
**prefix` out pointer that will get set to the allocated string and
subsequently be free'd by the caller.
While this patch increases the line count, I personally deem this to an
acceptable tradeoff for increased readbiblity.

util: do not perform allocations in insertsort
Our hand-rolled fallback sorting function `git__insertsort_r` does an
in-place sort of the given array. As elements may not necessarily be
pointers, it needs a way of swapping two values of arbitrary size, which
is currently implemented by allocating a temporary buffer of the
element's size. This is problematic, though, as the emulated `qsort`
interface doesn't provide any return values and thus cannot signal an
error if allocation of that temporary buffer has failed.
Convert the function to swap via a temporary buffer allocated on the
stack. Like this, it can `memcpy` contents of both elements in small
batches without requiring a heap allocation. The buffer size has been
chosen such that in most cases, a single iteration of copying will
suffice. Most importantly, it can fully contain `git_oid` structures and
pointers.
Add a bunch of tests for the `git__qsort_r` interface to verify nothing
breaks. Furthermore, this removes the declaration of `git__insertsort_r`
and makes it static as it is not used anywhere else.
