stash: call reflog_delete() in reflog.c

john-cai · gitster · commit 758b4d2be8c0 · 2022-03-02T15:24:47.000-08:00
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.
