78c844e578 PG: clear want_acting in choose_acting if want == acting 
Otherwise, a pg_temp from a previous peering sequence
(but not a different peering_interval) might leak through
into Active and incorrectly trip the
Active::react(AdvMap&) asserts regarding want_acting.
Those asserts assume that want_acting is either empty or is
a results of recovery completion.  In the latter case, the
want_acting set much consist only of elements of up and
acting.

9013efd3a3 osd: deep scrub, read file contents from disk and compare digest 
Deep scrub reads the contents of every file from the store and computes
a crc32 digest. The primary compares the digest of all replicas and will
mark the PG inconsistent if any don't match.

OSDs that do not support deep scrub simply perform an ordinary chunky
scrub. Any subset of OSDs that do support deep scrub will have their
digests compared.

f5046798f4 osd: chunky scrub, scrub PGs a chunk of objects at a time 
Chunky scrub is a more efficient scrub. It blocks writes on a subset of
objects and scrubs those, allowing writes through to the rest of the PG.

The scrub takes longer to complete than a classic scrub, but improves
overall write throughput.

This feature is backward-compatible with classic scrub. If the primary
detects that any replica does not have the chunky scrub feature, it
falls back to the less efficient classic scrub.

79b3054347 crush: change default type from 'pool' to 'root' 
The 'pool=default' in the default crush maps is confusing wrt rados pools.
'root' makes more sense given that we are talking about hierarchies/trees.

40fd6ba8ed OSD::handle_pg_stats_ack: grab pg refcount while processing pg 
If the queue refcount is the last one for the pg, the pg->put()
in the loop will destroy the pg while the lock is still held
leading to #3071.  Thus, grab refcount in case we need to drop
it.
