diff_tform: fix potential NULL pointer access
The `normalize_find_opts` function in theory allows for the
incoming diff to have no repository. When the caller does not
pass in diff find options or if the GIT_DIFF_FIND_BY_CONFIG value
is set, though, we try to derive the configuration from the
diff's repository configuration without first verifying that the
repository is actually set to a non-NULL value.
Fix this issue by explicitly checking if the repository is set
and if it is not, fall back to a default value of
GIT_DIFF_FIND_RENAMES.

rebase: plug memory leak in `rebase_alloc`
Convert `rebase_alloc` to use our usual error propagation
patterns, that is accept an out-parameter and return an error
code that is to be checked by the caller. This allows us to use
the GITERR_CHECK_ALLOC macro, which helps static analysis.

remote: set error code in `create_internal`
Set the error code when an error occurs in any of the called

index: fix contradicting comparison
The overflow check in `read_reuc` tries to verify if the
`git__strtol32` parses an integer bigger than UINT_MAX. The `tmp`
variable is casted to an unsigned int for this and then checked
for being greater than UINT_MAX, which obviously can never be
true.
Fix this by instead fixing the `mode` field's size in `struct
git_index_reuc_entry` to `uint32_t`. We can now parse the int
with `git__strtol64`, which can never return a value bigger than
`UINT32_MAX`, and additionally checking if the returned value is
smaller than zero.
We do not need to handle overflows explicitly here, as
`git__strtol64` returns an error when the returned value would
overflow.

common: introduce GITERR_CHECK_ALLOC_BUF
We commonly have to check if a git_buf has been allocated
correctly or if we ran out of memory. Introduce a new macro
similar to `GITERR_CHECK_ALLOC` which checks if we ran OOM and if
so returns an error. Provide a `#nodef` for Coverity to mark the
error case as an abort path.

refdb_fs: remove unnecessary check for NULL
The fail-label of `reflog_parse` explicitly checks the entry
poitner for NULL before freeing it. When we jump to the label the
variable has to be set to a non-NULL and valid pointer though: if
the allocation fails we immediately return with an error code and
if the loop was not entered we return with a success code,
withouth executing the label's code.
Remove the useless NULL-check to silence Coverity.

coverity: hint git_vector_foreach does not deref NULL contents
Coverity does not comprehend the connection between a vector's
size and the contents pointer, that is that the vector's pointer
is non-NULL when its size is positive. As the vector code should
be reasonably well tested and users are expected to not manually
modify a vector's contents it seems save to assume that the
macros will never dereference a NULL pointer.
Fix Coverity warnings by overriding the foreach macros with
macros that explicitly aborting when (v)->contents is NULL.

diff_print: assert patch is non-NULL
When invoking `diff_print_info_init_frompatch` it is obvious that
the patch should be non-NULL. We explicitly check if the variable
is set and continue afterwards, happily dereferencing the
potential NULL-pointer.
Fix this by instead asserting that patch is set. This also
silences Coverity.

pack-objects: return early when computing write order fails
The function `compute_write_order` may return a `NULL`-pointer
when an error occurs. In such cases we jump to the `done`-label
where we try to clean up allocated memory. Unfortunately we try
to deallocate the `write_order` array, though, which may be NULL
here.
Fix this error by returning early instead of jumping to the
`done` label. There is no data to be cleaned up anyway.

crlf: do not ignore GIT_PASSTHROUGH error
When no payload is set for `crlf_apply` we try to compute the
crlf attributes ourselves with `crlf_check`. When the function
determines that the current file does not require any treatment
we return the GIT_PASSTHROUGH error code without actually
allocating the out-pointer, which indicates the file should not
be passed through the filter.
The `crlf_apply` function explicitly checks for the
GIT_PASSTHROUGH return code and ignores it. This means we will
try to apply the crlf-filter to the current file, leading us to
dereference the unallocated payload-pointer.
Fix this obviously incorrect behavior by not treating
GIT_PASSTHROUGH in any special way. This is the correct thing to
do anyway, as the code indicates that the file should not be
passed through the filter.

signature: use GITERR_CHECK_ALLOC to check for OOM situation
When checking for out of memory situations we usually use the
GITERR_CHECK_ALLOC macro. Besides conforming to our current code
base it adds the benefit of silencing errors in Coverity due to
Coverity handling the macro's error path as abort.

coverity: hint that string length is at least 2
When checking if a string is prefixed by a drive letter (e.g.
"C:") we verify this by inspecting the first and second character
of the string. Coverity thinks this is a defect as we do not
check the string's length first, but in fact we only check the
second character if the first character is part of the alphabet,
that is it cannot be '\0'.
Fix this by overriding the macro and explicitly checking the
string's length.

win32: tests around handling forbidden paths
Introduce a repository that contains some paths that were illegal
on PC-DOS circa 1981 (like `aux`, `con`, `com1`) and that in a
bizarre fit of retrocomputing, remain illegal on some "modern"
computers, despite being "new technology".
Introduce some aspirational tests that suggest that we should be
able to cope with trees and indexes that contain paths that
would be illegal on the filesystem, so that we can at least diff
them. Further ensure that checkout will not write a repository
with forbidden paths.

When we moved the logic to handle the first one, wrong loop logic was

coverity: provide nodef for GITERR_CHECK_ALLOC
Coverity currently lists a lot of errors with regard to
GITERR_CHECK_ALLOC causing resource leaks. We know this macro is
only invoked when we want to abort because we are out of memory.
Coverity allows for overriding the default model where we know
that certain functions guarantee a desired behavior. The
user_nodefs.h is used to override the behavior of macros.
Re-define GITERR_CHECK_ALLOC inside of it to specify its abort
nature.

pack: do not free passed in poiter on error
The function `git_packfile_stream_open` tries to free the passed
in stream when an error occurs. The only call site is
`git_indexer_append`, though, which passes in the address of a
stream struct which has not been allocated on the heap.
Fix the issue by simply removing the call to free. In case of an
error we did not allocate any memory yet and otherwise it should
be the caller's responsibility to manage it's object's lifetime.

Better document `git_merge_commits` redux
`git_merge_commits` and `git_merge` now *do* handle recursive base
building for criss-cross merges. Remove the documentation that says
that they do not.
This reverts commit 5e44d9bcb6d5b20922f49b1913723186f8ced8b5.

filter: avoid races during filter registration
Previously we would set the global filter registry structure before
adding filters to the structure, without a lock, which is quite racy.
Now, register default filters during global registration and use an
rwlock to read and write the filter registry (as appopriate).
