Now that during a `git clone`, the hooks' contents are no longer
compared to the templates' files', the caller for which the
`do_files_match()` function was introduced is gone, and therefore this
function can be retired, too.
This reverts commit 584de0b4c2 (Add a helper function to compare file
contents, 2024-03-30).

In the next commit, Git will learn to disallow hooks during `git clone`
operations _except_ when those hooks come from the templates (which are
inherently supposed to be trusted). To that end, we add a function to
compare the contents of two files.

hash.h depends upon and includes repository.h, due to the definition and
use of the_hash_algo (defined as the_repository->hash_algo). However,
most headers trying to include hash.h are only interested in the layout
of the structs like object_id. Move the parts of hash.h that do not
depend upon repository.h into a new file hash-ll.h (the "low level"
parts of hash.h), and adjust other files to use this new header where
the convenience inline functions aren't needed.
This allows hash.h and object.h to be fairly small, minimal headers. It
also exposes a lot of hidden dependencies on both path.h (which was
brought in by repository.h) and repository.h (which was previously
implicitly brought in by object.h), so also adjust other files to be
more explicit about what they depend upon.

When copy_fd() function encounters errors, it emits error messages
itself, which makes it impossible for callers to take responsibility
for reporting errors, especially when they want to ignore certain
errors.
Move the error reporting to its callers in preparation.
- copy_file() and copy_file_with_time() by indirection get their
own calls to error().
- hold_lock_file_for_append(), when told to die on error, used to
exit(128) relying on the error message from copy_fd(), but now it
does its own die() instead. Note that the callers that do not
pass LOCK_DIE_ON_ERROR need to be adjusted for this change, but
fortunately there is none ;-)
- filter_buffer_or_fd() has its own error() already, in addition to
the message from copy_fd(), so this will change the output but
arguably in a better way.

The caller, not this function, opened the file descriptor; it is
selfish for the callee to close it when it is done reading from it.
The caller may want an option to rewind and re-read the contents
after it returns.
Simplify the loop to copy the input in full to the output; its
body essentially is what a call to write_in_full() helper does.

A local clone without hardlinks copies all objects, including dangling
ones, to the new repository. Since the mtimes are renewed, those
dangling objects cannot be pruned by "git gc --prune", even if they
would have been old enough for pruning in the original repository.
Instead, preserve mtime during copy. "git gc --prune" will then work
in the clone just like it did in the original.

This uses "git-apply --whitespace=strip" to fix whitespace errors that have
crept in to our source files over time. There are a few files that need
to have trailing whitespaces (most notably, test vectors). The results
still passes the test, and build result in Documentation/ area is unchanged.

This patch fixes all calls to xread() where the return value is not
stored into an ssize_t. The patch should not have any effect whatsoever,
other than putting better/more appropriate type names on variables.

We had errno==EINTR check after read(2)/write(2) sprinkled all
over the places, always doing continue. Consolidate them into
xread()/xwrite() wrapper routines.

git-pack-objects can reuse pack files stored in $GIT_DIR/pack-cache
directory, when a necessary pack is found. This is hopefully useful
when upload-pack (called from git-daemon) is expected to receive
requests for the same set of objects many times (e.g full cloning
request of any project, or updates from the set of heads previous day
to the latest for a slow moving project).
Currently git-pack-objects does *not* keep pack files it creates for
reusing. It might be useful to add --update-cache option to it,
which would allow it store pack files it created in the pack-cache
directory, and prune rarely used ones from it.
