refdb_fs: do not lazily copy packed ref cache
When creating a new iterator, we eagerly load loose refs but only lazily create
a copy of packed refs. The lazy load only happens as soon as we have iterated
over all loose refs, opening up a potentially wide window for races. This
may lead to an inconsistent view e.g. when the caller decides to reload packed
references somewhen between iterating the loose refs, which is unexpected.
Fix the issue by eagerly copying the sorted cache. Note that right now, we are
heavily dependent on ordering here: we first need to reload packed refs, then we
have to load loose refs and only as a last step are we allowed to copy the
cache. This is because loading loose refs has the side-effect of setting the
`PACKED_SHADOWED` flag in the packed refs cache, which we require to avoid
outputting packed refs that already exist as loose refs.

refdb_fs: fix potential race with ref repacking in `exists` callback
When repacking references, git.git will first update the packed refs and only
afterwards delete any existing loose references that have now been moved to the
new packed refs file. Due to this, there is a potential for racing if one first
reads the packfile (which has not been updated yet) and only then trying to read
the loose reference (which has just been deleted). In this case, one will
incorrectly fail to lookup the reference and it will be reported as missing.
Naturally, this is exactly what we've been doing in `refdb_fs_backend__exists`.
Fix the race by reversing the lookup: we will now first check if the loose
reference exists and only afterwards refresh the packed file.

branches: introduce flag to skip enumeration of certain HEADs
Right now, the function `git_repository_foreach_head` will always
iterate over all HEADs of the main repository and its worktrees. In some
cases, it might be required to skip either of those, though. Add a flag
in preparation for the following commit that enables this behaviour.

branches: do not assert that the given ref is a branch
Libraries should use assert(3P) only very scarcely. First, we usually
shouldn't cause the caller of our library to abort in case where the
assert fails. Second, if code is compiled with -DNDEBUG, then the assert
will not be included at all.
In our `git_branch_is_checked_out` function, we have an assert that
verifies that the given reference parameter is non-NULL and in fact a
branch. While the first check is fine, the second is not. E.g. when
compiled with -DNDEBUG, we'd proceed and treat the given reference as a
branch in all cases.
Fix the issue by instead treating a non-branch reference as not being
checked out. This is the obvious solution, as references other than
branches cannot be directly checked out.

branch: fix `branch_is_checked_out` with bare repos
In a bare repository, HEAD usually points to the branch that is
considered the "default" branch. As the current implementation for
`git_branch_is_checked_out` only does a comparison of HEAD with the
branch that is to be checked, it will say that the branch pointed to by
HEAD in such a bare repo is checked out.
Fix this by skipping the main repo's HEAD when it is bare.

worktree: error out early if given ref is not valid
When adding a new worktree, we only verify that an optionally given
reference is valid half-way through the function. At this point, some
data structures have already been created on-disk. If we bail out due to
an invalid reference, these will be left behind and need to be manually
cleaned up by the user.
Improve the situation by moving the reference checks to the function's
preamble. Like this, we error out as early as possible and will not
leave behind any files.

Similarly, do not define `GIT_DEPRECATE_HARD` within the library, or
those functions will also not get their export attributes. Define that
only on the tests and examples.

mbedtls: fix potential size overflow when reading or writing data
The mbedtls library uses a callback mechanism to allow downstream users
to plug in their own receive and send functions. We implement `bio_read`
and `bio_write` functions, which simply wrap the `git_stream_read` and
`git_stream_write` functions, respectively.
The problem arises due to the return value of the callback functions:
mbedtls expects us to return an `int` containing the actual number of
bytes that were read or written. But this is in fact completely
misdesigned, as callers are allowed to pass in a buffer with length
`SIZE_MAX`. We thus may be unable to represent the number of bytes
written via the return value.
Fix this by only ever reading or writing at most `INT_MAX` bytes.

mbedtls: make global variables static

openssl: fix potential size overflow when writing data
Our `openssl_write` function calls `SSL_write` by passing in both `data`
and `len` arguments directly. Thing is, our `len` parameter is of type
`size_t` and theirs is of type `int`. We thus need to clamp our length
to be at most `INT_MAX`.

streams: handle short writes only in generic stream
Now that the function `git_stream__write_full` exists and callers of
`git_stream_write` have been adjusted, we can lift logic for short
writes out of the stream implementations. Instead, this is now handled
either by `git_stream__write_full` or by callers of `git_stream_write`
directly.

streams: fix callers potentially only writing partial data
Similar to the write(3) function, implementations of `git_stream_write`
do not guarantee that all bytes are written. Instead, they return the
number of bytes that actually have been written, which may be smaller
than the total number of bytes. Furthermore, due to an interface design
issue, we cannot ever write more than `SSIZE_MAX` bytes at once, as
otherwise we cannot represent the number of bytes written to the caller.
Unfortunately, no caller of `git_stream_write` ever checks the return
value, except to verify that no error occurred. Due to this, they are
susceptible to the case where only partial data has been written.
Fix this by introducing a new function `git_stream__write_full`. In
contrast to `git_stream_write`, it will always return either success or
failure, without returning the number of bytes written. Thus, it is able
to write all `SIZE_MAX` bytes and loop around `git_stream_write` until
all data has been written. Adjust all callers except the BIO callbacks
in our mbedtls and OpenSSL streams, which already do the right thing and
require the amount of bytes written.

does not try to write more than `SSIZE_MAX` bytes (or smaller; if the
given implementation takes a smaller size).

iterator: cast filesystem iterator entry values explicitly
The filesystem iterator takes `stat` data from disk and puts them into
index entries, which use 32 bit ints for time (the seconds portion) and
filesize. However, on most systems these are not 32 bit, thus will
typically invoke a warning.
Most users ignore these fields entirely. Diff and checkout code do use
the values, however only for the cache to determine if they should check
file modification. Thus, this is not a critical error (and will cause a
hash recomputation at worst).

index: preserve extension parsing errors
Previously, we would clobber any extension-specific error message with
an "extension is truncated" message. This makes `read_extension`
correctly preserve those errors, takes responsibility for truncation
errors, and adds a new message with the actual extension signature for
unsupported mandatory extensions.

git_error: use full class name in public error API
Move to the `git_error` name in error-related functions, deprecating the
`giterr` functions. This means, for example, that `giterr_last` is now
`git_error_last`. The old names are retained for compatibility.
This only updates the public API; internal API and function usage
remains unchanged.

Fix odb foreach to also close on positive error code
In include/git2/odb.h it states that callback can also return
positive value which should break looping.
Implementations of git_odb_foreach() and pack_backend__foreach()
did not respect that.
