Because HEAD and stash are per-worktree, every refs backend needs to
go through the files backend to write these refs.
So create a new function, files_log_ref_write, and add it to
refs/refs-internal.h. Later, we will use this to handle reflog updates
for per-worktree symbolic refs (HEAD).

As another step in the move to pluggable reference backends, move the
code that is specific to the filesystem-based reference backend (i.e.,
the current system of storing references as loose and packed files) into
a separate file, refs/files-backend.c.
Aside from a tiny bit of file header boilerplate, this commit only moves
a subset of the code verbatim from refs.c to the new file, as can easily
be verified using patience diff:

There are a number of constants, structs, and static functions defined
in refs.c and treated as private to the references module. But we want
to support multiple reference backends within the reference module,
and those backends will need access to some heretofore private
declarations.
We don't want those declarations to be visible to non-refs code, so we
don't want to move them to refs.h. Instead, add a new header file,
refs/refs-internal.h, that is intended to be included only from within
the refs module. Make some functions non-static and move some
declarations (and their corresponding docstrings) from refs.c to this
file.
In a moment we will add more content to the "refs" subdirectory.

is_per_worktree_ref() will soon be made private, so use the public
interface, ref_type(), in its place. And now that we're using
ref_type(), we can make it clear that we won't pack pseudorefs. This was
the case before, but due to the not-so-obvious reason that this function
is applied to references via the loose reference cache, which only
includes references that live inside "refs/".

Commit f8117f55 ("http: use off_t to store partial file size",
02-11-2015) changed the type of some variables from long to off_t.
Unfortunately, the off_t type is not portable and can be represented
by several different actual types (even multiple types on the same
platform). This makes it difficult to print an off_t variable in
a platform independent way. As a result, this commit causes gcc to
issue some printf format warnings on a couple of different platforms.
In order to suppress the warnings, change the format specifier to use
the PRIuMAX macro and cast the off_t argument to uintmax_t. (See also
the http_opt_request_remainder() function, which uses the same
solution).

Processing empty_dir directives becomes extremely slow for svn
repositories with a large enough history.
This is due to using a single hash to store the list of empty
directories, with the expensive step being purging items from
that hash using grep+delete.
Storing directories in a hash of hashes improves the performance
of this purge step and removes a potentially lengthy delay after
every rebase/mkdirs command.
The svn repository with this behaviour has 110K commits with
unhandled.log containing 170K empty_dir directives.
This takes 10 minutes to process when using a single hash, vs
3 seconds with a hash of hashes.

If the user specifies an index filter but not a tree filter,
filter-branch cleverly avoids checking out the tree
entirely. But we don't do the next level of optimization: if
you have no index or tree filter, we do not need to read the
index at all.
This can greatly speed up cases where we are only changing
the commit objects (e.g., cementing a graft into place).

Using the previous commit's inredirection mechanism for SHA1,
support a chunked implementation of SHA1_Update() that limits the
amount of data in the chunk passed to SHA1_Update().
This is enabled by using the Makefile variable SHA1_MAX_BLOCK_SIZE
to specify chunk size. When using Apple's CommonCrypto library this
is set to 1GiB (the implementation cannot handle more 4GiB).

The git source uses git_SHA1_Update() and friends to call into the
code that computes the hashes. Traditionally, we used to map these
directly to underlying implementation of the SHA-1 hash (e.g.
SHA1_Update() from OpenSSL or blk_SHA1_Update() from block-sha1/).
This arrangement however makes it hard to tweak behaviour of the
underlying implementation without fully replacing. If we want to
introduce a tweaked_SHA1_Update() wrapper to implement the "Update"
in a slightly different way, for example, the implementation of the
wrapper still would want to call into the underlying implementation,
but tweaked_SHA1_Update() cannot call git_SHA1_Update() to get to
the underlying implementation (often but not always SHA1_Update()).
Add another level of indirection that maps platform_SHA1_Update()
and friends to their underlying implementations, and by default make
git_SHA1_Update() and friends map to platform_SHA1_* functions.
Doing it this way will later allow us to map git_SHA1_Update() to
tweaked_SHA1_Update(), and the latter can use platform_SHA1_Update()
in its implementation.
