This version hopefully addresses the weirdness of passing the
lock->old_oid as the "oid". We still do so, but the "refs API: pass
the "lock OID" to reflog "prepare"" and its change from s/const// is
gone, instead the relevant (and much smaller) part of that is squashed
into the "reflog expire: don't lock reflogs using previously seen OID"
change.
Ævar Arnfjörð Bjarmason (11):
refs/packet: add missing BUG() invocations to reflog callbacks
refs/files: remove unused REF_DELETING in lock_ref_oid_basic()
refs/files: remove unused "extras/skip" in lock_ref_oid_basic()
refs/files: remove unused "skip" in lock_raw_ref() too
refs/debug: re-indent argument list for "prepare"
refs: make repo_dwim_log() accept a NULL oid
refs/files: add a comment about refs_reflog_exists() call
reflog expire: don't lock reflogs using previously seen OID
refs/files: remove unused "oid" in lock_ref_oid_basic()
refs/files: remove unused "errno == EISDIR" code
refs/files: remove unused "errno != ENOTDIR" condition

I'm leaving behind now-unused code the refs API etc. that takes the

that we never have on OID in that context, that'll be cleaned up in
subsequent commits, but for now let's narrowly focus on fixing the
"git gc" issue. As the modified assert() shows we always pass a NULL
