The printing functionality part of `reftable/dump.c` is really only used
by our "dump-reftable" test helper. It is certainly not generic logic
that is useful to anybody outside of Git, and the format it generates is
quite specific. Still, parts of it are used in our test suite and the
output may be useful to take a peek into reftable stacks, tables and
blocks. So while it does not make sense to expose this as part of the
reftable library, it does make sense to keep it around.
Inline the `reftable_dump_main()` function into the "dump-reftable" test
helper. This clarifies that its format is subject to change and not part
of our public interface. Furthermore, this allows us to iterate on the
implementation in subsequent patches.

The `compact_stack()` function is exposed via `reftable_dump_main()`,
which ultimately ends up being wired into "test-tool reftable". It is
never used by our tests though, and nowadays we have wired up support
for stack compaction into git-pack-refs(1).
Remove the code.

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.

We're about to introduce new configs that will allow users to have more
control over how exactly reftables are written. To verify that these
configs are effective we will need to take a peak into the actual blocks
written by the reftable backend.
Introduce a new mode to the dumping logic that prints out the block
structure. This logic can be invoked via `test-tool dump-reftables -b`.

We sometimes pass the refatble write options as value and sometimes as a
pointer. This is quite confusing and makes the reader wonder whether the
options get modified sometimes.
In fact, `reftable_new_writer()` does cause the caller-provided options
to get updated when some values aren't set up. This is quite unexpected,
but didn't cause any harm until now.
Adapt the code so that we do not modify the caller-provided values
anymore. While at it, refactor the code to code to consistently pass the
options as a constant pointer to clarify that the caller-provided opts
will not ever get modified.

Throughout the reftable library the `reftable_write_options` are
sometimes referred to as `cfg` and sometimes as `opts`. Unify these to
consistently use `opts` to avoid confusion.
While at it, touch up the coding style a bit by removing unneeded braces
around one-line statements and newlines between variable declarations.

Each of these were checked with
gcc -E -I. ${SOURCE_FILE} | grep ${HEADER_FILE}
to ensure that removing the direct inclusion of the header actually
resulted in that header no longer being included at all (i.e. that
no other header pulled it in transitively).
...except for a few cases where we verified that although the header
was brought in transitively, nothing from it was directly used in
that source file. These cases were:
* builtin/credential-cache.c
* builtin/pull.c
* builtin/send-pack.c

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.
