Re: [PATCH v2 2/3] reflog: libify delete reflog function and helpers

Currently stash shells out to reflog in order to delete refs. In an
effort to reduce how much we shell out to a subprocess, libify the
functionality that stash needs into reflog.c.

Add a reflog_delete function that is pretty much the logic in the while
loop in builtin/reflog.c cmd_reflog_delete(). This is a function that
builtin/reflog.c and builtin/stash.c can both call.

Also move functions needed by reflog_delete and export them.

This round, without polluting global namespace in reflog.h by moving
too many things there and instead keeping what is private to the
implementation in reflog.c, looks much better than the previous
round.

Looking good.

Thanks.
