bmstore: add handling of the active bookmark
This further centralizes the handling of bookmark storage, and will
help get some lingering bookmarks business out of localrepo. Right
now, this change implies reading of the active bookmark to also imply
reading all bookmarks from disk - for users with many many bookmarks
this may be a measurable performance hit. In that case, we should
migrate bmstore to be able to lazy-read its properties from disk
rather than having to eagerly read them, but I decided to avoid doing
that to try and avoid some potentially complicated filecache decorator
issues.
This doesn't move the logic for writing the active bookmark into a
transaction, though that is probably the correct next step. Since the
API probably needs to morph a little more, I didn't bother marking
bookmarks.{activate,deactivate} as deprecated yet.
