Jeff King 3fa6f2aa57 cache.h: move hash/oid functions to hash.h ...

We define git_hash_algo and object_id in hash.h, but most of the utility
functions are declared in the main cache.h. Let's move them to hash.h
along with their struct definitions. This cleans up cache.h a bit, but
also avoids circular dependencies when other headers need to know about
these functions (e.g., if oid-array.h were to have an inline that used
oideq(), it couldn't include cache.h because it is itself included by
cache.h).

No including C files should be affected, because hash.h is always
included in cache.h already.

We do have to mention repository.h at the top of hash.h, though, since
we depend on the_repository in some of our inline functions.
