osd: clean up src_oid, src_obc map key calculation
Be consistent about how we generate the src_oid and src_oloc, so that we
feed good value into find_object_context and use a consistent key for
the src_obc map<>. This fixes a crash in do_osd_ops() due to a missing
src_obc key when the get_src_oloc() normalizes the key in do_op() but not
in do_osd_ops().
Also use a nicer name.

The OSDMap NEW and AUTOOUT bit additions subtely change the decoding of

care what clients see, since those bits are informational only.

osd: initialize backfill_pos on activate
Handling of writes depends on backfill_pos being initialized (to know what
is between the leading and trailing edge of the backfill), so it needs to
be initialized at activate time to avoid badness on writes prior to
recovery starting.
- initialize during activate to last_backfill
- update on receiving the digest to maintain the invariant that
backfill_pos = min(peer_backfill_info.start, backfill_info.start)
in recover_backfill().

osd: do not use incomplete peer for best info/log
For one, their stats are incomplete; if we use them we'll screw up everyone
else. For another, it doesn't do us any good if they are a bit ahead of
the peers: we/they may not even have the objects their newer log says were
updated. The only real use is if their log extends farther back in time,
but that is a problem in general that we'll eventually solve in other ways.
On the other hand, having the pg_stats sum only through last_backfill may
not have been the best choice; we could avoid that part of things by adding
a objects_backfilled field. But this is probably a good idea anyway.

A single WriteOp already does multiple aio_writes. Each aio_write

osd: trigger RecoveryFinished event on recovery completion
Unconditionally trigger the RecoveryFinished event when start_recvoery_ops
