signature: fix out-of-bounds read when parsing timezone offset
When parsing a signature's timezone offset, we first check whether there
is a timezone at all by verifying that there are still bytes left to
read following the time itself. The check thus looks like `time_end + 1
< buffer_end`, which is actually correct in this case. After setting the
timezone's start pointer to that location, we compute the remaining
bytes by using the formula `buffer_end - tz_start + 1`, re-using the
previous `time_end + 1`. But this is in fact missing the braces around
`(tz_start + 1)`, thus leading to an overestimation of the remaining
bytes by a length of two. In case of a non-NUL terminated buffer, this
will result in an overflow.
The function `git_signature__parse` is only used in two locations. First
is `git_signature_from_buffer`, which only accepts a string without a
length. The string thus necessarily has to be NUL terminated and cannot
trigger the issue.
The other function is `git_commit__parse_raw`, which can in fact trigger
the error as it may receive non-NUL terminated commit data. But as
objects read from the ODB are always NUL-terminated by us as a
cautionary measure, it cannot trigger the issue either.
In other words, this error does not have any impact on security.

treewide: remove use of C++ style comments
C++ style comment ("//") are not specified by the ISO C90 standard and
thus do not conform to it. While libgit2 aims to conform to C90, we did
not enforce it until now, which is why quite a lot of these
non-conforming comments have snuck into our codebase. Do a tree-wide
conversion of all C++ style comments to the supported C style comments
to allow us enforcing strict C90 compliance in a later commit.

signature: distinguish +0000 and -0000 UTC offsets
Git considers '-0000' a valid offset for signature lines. They need to
be treated as _not_ equal to a '+0000' signature offset. Parsing a
signature line stores the offset in a signed integer which does not
distinguish between `+0` and `-0`.
This patch adds an additional flag `sign` to the `git_time` in the
`signature` object which is populated with the sign of the offset. In
addition to exposing this information to the user, this information is
also used to compare signatures.

Fix initial commit test
`test_commit_commit__create_initial_commit_parent_not_current` was not correctly
testing that `HEAD` was not changed. Now we grab the oid that it was pointing to
before the call to `git_commit_create` and the oid that it's pointing to afterwards
and compare those.

commit: fix extraction of single-line signatures
The function to extract signatures suffers from a similar bug to the

break condition of its loop.
Fix that and add a test for this single-line signature situation.

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.

commit: don't forget the last header field
When we moved the logic to handle the first one, wrong loop logic was
kept in place which meant we still finished early. But we now notice it
because we're not reading past the last LF we find.
This was not noticed before as the last field in the tested commit was
multi-line which does not trigger the early break.

While here, make sure to set an error message in case we cannot find the
field.

commit: ignore multiple author fields
Some tools create multiple author fields. git is rather lax when parsing
them, although fsck does complain about them. This means that they exist
in the wild.
As it's not too taxing to check for them, and there shouldn't be a
noticeable slowdown when dealing with correct commits, add logic to skip
over these extra fields when parsing the commit.

Remove the signature from ref-modifying functions
The signature for the reflog is not something which changes
dynamically. Almost all uses will be NULL, since we want for the
repository's default identity to be used, making it noise.
In order to allow for changing the identity, we instead provide
git_repository_set_ident() and git_repository_ident() which allow a user
to override the choice of signature.

commit: safer commit creation with reference update
The current version of the commit creation and amend function are unsafe
to use when passing the update_ref parameter, as they do not check that
the reference at the moment of update points to what the user expects.
Make sure that we're moving history forward when we ask the library to
update the reference for us by checking that the first parent of the new
commit is the current value of the reference. We also make sure that the
ref we're updating hasn't moved between the read and the write.
Similarly, when amending a commit, make sure that the current tip of the
branch is the commit we're amending.
