notes-cache: convert to struct object_id

Convert as many instances of unsigned char [20] as possible.  Update the
callers of notes_cache_get and notes_cache_put to use the new interface.
Among the functions updated are callers of
lookup_commit_reference_gently, which we will soon convert.

introduce notes-cache interface

Notes provide a fast lookup mechanism for data keyed by
sha1. This is ideal for caching certain operations, like
textconv filters.

This patch builds some infrastructure to make it simpler to
use notes trees as caches. In particular, caches:

  1. don't have arbitrary commit messages. They store a
     cache validity string in the commit, and clear the tree
     when the cache validity string changes.

  2. don't keep any commit history. The accumulated history
     of a a cache is just useless cruft.

  3. use a looser form of locking for ref updates. If two
     processes try to write to the cache simultaneously, it
     is OK if one overwrites the other, losing some changes.
     It's just a cache, so we will just end up with an extra
     miss.
