5155baf323 osd: handle NOUP flag vs boot race 
If we digest maps that show a NOUP flag change *and* we also go active,
there is no need to restart the boot process--we can just go/stay active.

29a885c915 qa/suites/rados/singleton/all/recovery_preemption: make test more reliable 
A 30 second run did only 7000 ops, which means ~50 log entires per pg...
not enough to trigger backfill.

ce699ff870 osd: close split vs query race in consume_map 
Consider the race:

- shard 0 consumes epoch E
- shard 1 consumes epoch E
  - shard 1 pg P will split to C
- shard 0 processes query on C, returns DNE
- shard 0 primes slot C

Close race by priming split children before consuming map into each
OSDShard.  That way the query will either (1) arrive before E and before
slot C is primed and wait for E, or find the slot present with
waiting_for_split true.
