958f964691 refs: split ref_cache code into separate files
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.

524a9fdb51 refs_verify_refname_available(): use function in more places
Change `lock_raw_ref()` and `lock_ref_sha1_basic()` to use
`refs_verify_refname_available()` instead of
`verify_refname_available_dir()`. This means that those callsites now
check for conflicts with all references rather than just packed refs,
but the performance cost shouldn't be significant (and will be
regained later).

These were the last callers of `verify_refname_available_dir()`, so
also delete that (very complicated) function.

b05855b5bc refs_verify_refname_available(): implement once for all backends
It turns out that we can now implement
`refs_verify_refname_available()` based on the other virtual
functions, so there is no need for it to be defined at the backend
level. Instead, define it once in `refs.c` and remove the
`files_backend` definition.

68fb02e40d get_ref_dir(): don't call read_loose_refs() for "refs/bisect"
Since references under "refs/bisect/" are per-worktree, they have to
be sought in the worktree rather than in the main repository. But
since loose references are found by traversing directories, the
reference iterator won't even get the idea to look for a
"refs/bisect/" directory in the worktree if there is not a directory
with that name in the main repository. Thus `get_ref_dir()` manually
inserts a dir_entry for "refs/bisect/" whenever it reads the entry for
"refs/".

The current code then immediately calls `read_loose_refs()` on that
directory. But since the dir_entry is created with its `incomplete`
flag set, any traversal that gets to this point will read the
directory automatically. So there is no need to call
`read_loose_refs()` explicitly; the lazy mechanism suffices.

And in fact, the attempt to `read_loose_refs()` was broken anyway.
That function needs its `dirname` argument to have a trailing `/`
character, but the invocation here was passing it "refs/bisect"
without a trailing slash. So `read_loose_refs()` would read
`$GIT_DIR/refs/bisect" correctly, but if it found an entry "foo" in
that directory, it would try to read "$GIT_DIR/refs/bisectfoo".
Normally it wouldn't find anything at that path, but the failure was
canceled out because `get_ref_dir()` *also* forgot to reset the
`REF_INCOMPLETE` bit on the dir_entry. So the read was attempted again
when it was accessed, via the lazy mechanism, and this time the read
was done correctly.

This code has been broken since it was first introduced.

2f40e95472 files-backend: avoid ref api targeting main ref store
A small step towards making files-backend work as a non-main ref store
using the newly added store-aware API.

For the record, `join` and `nm` on refs.o and files-backend.o tell me
that files-backend no longer uses functions that default to
get_main_ref_store().

I'm not yet comfortable at the idea of removing
files_assert_main_repository() (or converting REF_STORE_MAIN to
REF_STORE_WRITE). More staring and testing is required before that can
happen. Well, except peel_ref(). I'm pretty sure that function is safe.

9e7ec634a1 files-backend: replace submodule_allowed check in files_downcast()
files-backend.c is unlearning submodules. Instead of having a specific
check for submodules to see what operation is allowed, files backend
now takes a set of flags at init. Each operation will check if the
required flags is present before performing.

For now we have four flags: read, write and odb access. Main ref store
has all flags, obviously, while submodule stores are read-only and have
access to odb (*).

The "main" flag stays because many functions in the backend calls
frontend ones without a ref store, so these functions always target the
main ref store. Ideally the flag should be gone after ref-store-aware
api is in place and used by backends.

(*) Submodule code needs for_each_ref. Try take REF_STORE_ODB flag
out. At least t3404 would fail. The "have access to odb" in submodule is
a bit hacky since we don't know from he whether add_submodule_odb() has
been called.

5d0bc90e5d refs: move submodule code out of files-backend.c
files-backend is now initialized with a $GIT_DIR. Converting a submodule
path to where real submodule gitdir is located is done in get_ref_store().

This gives a slight performance improvement for submodules since we
don't convert submodule path to gitdir at every backend call like
before. We pay that once at ref-store creation.

More cleanup in files_downcast() and files_assert_main_repository()
follows shortly. It's separate to keep noises from this patch.

1eab194bf0 files-backend: delete dead code in files_init_db()
safe_create_dir() can do adjust_shared_perm() internally, and init-db
has always created 'refs' in shared mode since the beginning,
af6e277c5e (git-init-db: initialize shared repositories with --shared -
2005-12-22). So this code looks like extra adjust_shared_perm calls are
unnecessary.

And they are. But let's see why there are here in the first place.

This code was added in 6fb5acfd8f (refs: add methods to init refs db -
2016-09-04). From the diff alone this looks like a faithful refactored
code from init-db.c. But there is a subtle difference:

Between the safe_create_dir() block and adjust_shared_perm() block in
the old init-db.c, we may copy/recreate directories from the repo
template. So it makes sense that adjust_shared_perm() is re-executed
then to fix potential permission screwups.

After 6fb5acfd8f, refs dirs are created after template is copied. Nobody
will change directory permission again. So the extra adjust_shared_perm()
is redudant. Delete them.
