Since ref iterators do not hold onto the direct value of a reference
without resolving it, the only way to get ahold of a direct value of a
symbolic ref is to make a separate call to refs_read_symbolic_ref.
To make accessing the direct value of a symbolic ref more efficient,
let's save the direct value of the ref in the iterators for both the
files backend and the reftable backend.

The "hash-ll.h" header was introduced via d1cbe1e6d8 (hash-ll.h: split
out of hash.h to remove dependency on repository.h, 2023-04-22) to make
explicit the split between hash-related functions that rely on the
global `the_repository`, and those that don't. This split is no longer
necessary now that we we have removed the reliance on `the_repository`.
Merge "hash-ll.h" back into "hash.h". This causes some code units to not
include "repository.h" anymore, which requires us to add some forward
declarations.

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.

We had a handful of headers including cache.h that didn't need to
anymore. Drop those includes and replace them with includes of
smaller files, or forward declarations. However, note that two .c
files now need to directly include cache.h, though they should have
been including it all along given they are directly using structs
defined in it.

Follow through the work to use the repo interface to access
submodule objects in-process, instead of abusing the alternate
object database interface.
* jt/no-abuse-alternate-odb-for-submodules:
submodule: trace adding submodule ODB as alternate
submodule: pass repo to check_has_commit()
object-file: only register submodule ODB if needed
merge-{ort,recursive}: remove add_submodule_odb()
refs: peeling non-the_repository iterators is BUG
refs: teach arbitrary repo support to iterators
refs: plumb repo into ref stores
|

There is currently no support for peeling the current ref of an iterator
iterating over a non-the_repository ref store, and none is needed. Thus,
for now, BUG() if that happens.

Remove the now-unused "incomplete" parameter from create_dir_entry(),
all its callers specify it as "1", so let's drop the "incomplete=0"
case. The last caller to use it was search_for_subdir(), but that code
was removed in the preceding commit.

Now that the `packed-refs` backend doesn't use `ref_cache`, there is
nobody left who might want to store peeled values of references in
`ref_cache`. So remove that feature.

References are iterated over in order by refname, but reflogs are not.
Some consumers of reference iteration care about the difference. Teach
each `ref_iterator` to keep track of whether its output is ordered.
`overlay_ref_iterator` is one of the picky consumers. Add a sanity
check in `overlay_ref_iterator_begin()` to verify that its inputs are
ordered.

Teach `read_packed_refs()` to also
* Allocate and initialize the new `packed_ref_cache`
* Open and close the `packed-refs` file
* Update the `validity` field of the new object
This decreases the coupling between `packed_refs_cache` and
`files_ref_store` by a little bit.

Convert many of the internals of the files backend to use struct
object_id. Avoid converting public APIs (except one change to
refs/ref-cache.c) to limit the scope of the changes.
Convert one use of get_sha1_hex to parse_oid_hex, and rely on the fact
that a strbuf will be NUL-terminated and that parse_oid_hex will fail on
truncated input to avoid the need to check the length.
This is a requirement to convert parse_object later on.

Change `cache_ref_iterator_begin()` to take two new arguments:
* `prefix` -- to iterate only over references with the specified
prefix.
* `prime_dir` -- to "prime" (i.e., pre-load) the cache before starting
the iteration.
The new functionality makes it possible for
`files_ref_iterator_begin()` to be made more ignorant of the internals
of `ref_cache`, and `find_containing_dir()` and `prime_ref_dir()` to
be made private.

It is a leveling violation for `ref_cache` to know about
`files_ref_store` or that it should call `read_loose_refs()` to lazily
fill cache directories. So instead, have its constructor take as an
argument a callback function that it should use for lazy-filling, and
change `files_ref_store` to supply a pointer to function
`read_loose_refs` (renamed to `loose_fill_ref_dir`) when creating the
ref cache for its loose refs.
This means that we can generify the type of the back-pointer in
`struct ref_cache` from `files_ref_store` to `ref_store`.

Instead of keeping a pointer to the `ref_store` in every `ref_dir`
entry, store it once in `struct ref_cache`, and change `struct
ref_dir` to include a pointer to its containing `ref_cache` instead.
This makes it easier to add to the information that is accessible from
a `ref_dir` without increasing the size of every `ref_dir` instance.
Note that previously, every `ref_dir` pointed at the containing
`files_ref_store` regardless of whether it was a part of the loose or
packed reference cache. Now we have to be sure to initialize the
instances to point at the correct containing `ref_cache`. So change
`create_dir_entry()` to take a `ref_cache` parameter, and change its
callers to pass the correct `ref_cache` depending on the purpose of
the new `dir_entry`.

For now, it just wraps a `ref_entry *` that points at the root of the
tree. Soon it will hold more information.
Add two new functions, `create_ref_cache()` and `free_ref_cache()`.
Make `free_ref_entry()` private.
Change files-backend to use this type to hold its caches.

The `ref_cache` code is currently too tightly coupled to
`files-backend`, making the code harder to understand and making it
awkward for new code to use `ref_cache` (as we indeed have planned).
Start loosening that coupling by splitting `ref_cache` into a separate
module.
This commit moves code, adds declarations, and changes the visibility
of some functions, but doesn't change any code.
The modules are still too tightly coupled, but the situation will be
improved in subsequent commits.
