[PATCH 3/3] stash: call reflog_delete from reflog.c

["John Cai via GitGitGadget" <gitgitgadget@gmail.com>]

From: John Cai <johncai86@gmail.com>

Now that cmd_reflog_delete has been libified an exported it into a new
reflog.c library so we can call it directly from builtin/stash.c. This
not only gives us a performance gain since we don't need to create a
subprocess, but it also allows us to use the ref transactions api in the
future.
