Now that resolve_ref_unsafe's only interaction with the backend is
through read_raw_ref, we can move it into the common code. Later,
we'll replace read_raw_ref with a backend function.

Make do_for_each_ref take a submodule as an argument instead of a
ref_cache. Since all for_each_*ref* functions are defined in terms of
do_for_each_ref, we can then move them into the common code.
Later, we can simply make do_for_each_ref into a backend function.

Create new function find_descendant_ref, to hold one of the ref
conflict checks used in verify_refname_available. Multiple backends
will need this function, so move it to the common code.
Also move rename_ref_available to the common code, because alternate
backends might need it and it has no files-backend-specific code.

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).

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.
