commit: fix extraction of single-line signatures
The function to extract signatures suffers from a similar bug to the
header field finding one by having an unecessary line feed check as a
break condition of its loop.
Fix that and add a test for this single-line signature situation.

Split the page size from the mmap alignment
While often similar, these are not the same on Windows. We want to use the page
size on Windows for the pools, but for mmap we need to use the allocation
granularity as the alignment.
On the other platforms these values remain the same.

Setup better defaults for OpenSSL ciphers
This ensures that when using OpenSSL a safe default set of ciphers
is selected. This is done so that the client communicates securely
and we don't accidentally enable unsafe ciphers like RC4, or even
worse some old export ciphers.
Implements the first part of https://github.com/libgit2/libgit2/issues/3682

config_cache: check return value of `git_config__lookup_entry`
Callers of `git_config__cvar` already handle the case where the
function returns an error due to a failed configuration variable
lookup, but we are actually swallowing errors when calling
`git_config__lookup_entry` inside of the function.
Fix this by returning early when `git_config__lookup_entry`
returns an error. As we call `git_config__lookup_entry` with
`no_errors == false` which leads us to call `get_entry` with
`GET_NO_MISSING` we will not return early when the lookup fails
due to a missing entry. Like this we are still able to set the
default value of the cvar and exit successfully.

config_file: handle error when trying to lock strmap
Accessing the current values map is handled through the
`refcounder_strmap_take` function, which first acquires a mutex
before accessing its values. While this assures everybody is
trying to access the values with the mutex only we do not check
if the locking actually succeeds.
Fix the issue by checking if acquiring the lock succeeds and
returning `NULL` if we encounter an error. Adjust callers.

return an error and handle the error in `git_blame_file`.

refdb_fs: fail if refcache returns NULL pointer

it really should not happen that the function returns NULL.

diff_tform: fix potential NULL pointer access
When the user passes in a diff which has no repository associated
we may call `git_config__get_int_force` with a NULL-pointer
configuration. Even though `git_config__get_int_force` is
designed to swallow errors, it is not intended to be called with
a NULL pointer configuration.
Fix the issue by only calling `git_config__get_int_force` only
when configuration could be retrieved from the repository.

submodule: avoid passing NULL pointers to strncmp
In C89 it is undefined behavior to pass `NULL` pointers to
`strncmp` and later on in C99 it has been explicitly stated that
functions with an argument declared as `size_t nmemb` specifying
the array length shall always have valid parameters, no matter if
`nmemb` is 0 or not (see ISO 9899 §7.21.1.2).
The function `str_equal_no_trailing_slash` always passes its
parameters to `strncmp` if their lengths match. This means if one
parameter is `NULL` and the other one either `NULL` or a string
with length 0 we will pass the pointers to `strncmp` and cause
undefined behavior.
Fix this by explicitly handling the case when both lengths are 0.

object: avoid call of memset with ouf of bounds pointer
When computing a short OID we do this by first copying the
leading parts into the new OID structure and then setting the
trailing part to zero. In the case of the desired length being
`GIT_OID_HEXSZ - 1` we will call `memset` with an out of bounds
pointer and a length of 0. While this seems to cause no problems
for common platforms the C89 standard does not explicitly state
that calling `memset` with an out of bounds pointer and
length of 0 is valid.
Fix the potential issue by using the newly introduced
`git_oid__cpy_prefix` function.

config_file: handle missing quotation marks in section header
When parsing a section header we expect something along the
format of '[section "subsection"]'. When a section is
mal-formated and is entirely missing its quotation marks we catch
this case by observing that `strchr(line, '"') - strrchr(line,
'"') = NULL - NULL = 0` and error out. Unfortunately, the error
message is misleading though, as we state that we are missing the
closing quotation mark while we in fact miss both quotation
marks.
Improve the error message by explicitly checking if the first
quotation mark could be found and, if not, stating that quotation
marks are completely missing.

The old implementation had two issues:
1. OIDs that were too short as to be ambiguous were not being handled

2. If the last OID to expand in the array was missing from the ODB, we
would leak a `GIT_ENOTFOUND` error code from the function.

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.

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.

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.

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.

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.

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.

index: allow read of index w/ illegal entries
Allow `git_index_read` to handle reading existing indexes with
illegal entries. Allow the low-level `git_index_add` to add
properly formed `git_index_entry`s even if they contain paths
that would be illegal for the current filesystem (eg, `AUX`).
Continue to disallow `git_index_add_bypath` from adding entries
that are illegal universally illegal (eg, `.git`, `foo/../bar`).

iterator: assert tree_iterator has a frame
Although a `tree_iterator` that failed to be properly created
does not have a frame, all other `tree_iterator`s should. Do not
call `pop` in the failure case, but assert that in all other
cases there is a frame.

Validate pointer before access the member.
When Git repository at network locations, sometimes git_iterator_for_tree
fails at iterator__update_ignore_case so it goes to git_iterator_free.
Null pointer will crash the process if not check.

commit: expose the different kinds of errors
We should be checking whether the object we're looking up is a commit,
and we should let the caller know whether the not-found return code
comes from a bad object type or just a missing signature.
