Remove unused methods

The direct-writes commit left some (slow) internals methods that
were no longer needed. These have been removed.

Also, the Reflog code was using the old `git_signature__write`, so
it has been rewritten to use a normal buffer and the new `writebuf`
signature writer. It's now slightly simpler and faster.
