ReplicatedPG: remove faulty scrub assert in sub_op_modify_applied
This assert assumed that all ops submitted before MOSDRepScrub was
submitted were processed by the time that MOSDRepScrub was
processed. In fact, MOSDRepScrub's scrub_to may refer to a
last_update yet to be seen by the replica.

rest-bench: mark request as complete later
We marked a request as complete in the callback, however
it might be that we're still inside S3_runall_request_context()
which means that request is not really complete yet.
Possibly fixes bug #2652.
If we play 1-4 and then replay 1-4 again, we will end up removing
(b, 1)'s attributes since nlink for (a, 1) the second time through
is 1. We fix this by marking spos on the object_map header for
(a, 1) when we remove (a, 1) but not eh attributes.
- keyrings have new default locations that everyone should use.
- the user key setup is vastly simplified if you use the
'ceph auth get-or-create' command.
mon: MonmapMonitor: Use default port when the specified on 'add' is zero
Fixes a bug triggered by using the ceph tool to 'mon add' with a port set
to zero. We now default to the monitor's default port (6789) instead, and
we will fail if that port is already assigned to some other monitor.

objecter: do not feed session to op_submit()
The linger_send() method was doing this, but it is problematic because the
new Op doesn't get its pgid or acting vector set correctly. The result is
that the request goes to the right OSD, but has the wrong pgid, and makes
the OSD complain about misdirected requests and drop it on the floor. It
didn't affect the test results because we weren't testing whether the
watch was working in that case.
Instead, we'll just recalculate and get the same value the parent linger
op did. Which is fine, and goes through all the usual code paths so
nothing is missed.
Also, increment num_homeless_ops before we recalc_op_target(), so that we
don't (harmlessly, but confusingly) underflow.

mon: encoding new monmap using quorum feature set
It is probably unlikely that someone will expand the mon cluster with a
mixed feature set, but we know the quorum features here, so we should use

mon: conditionally encode auth incremental with quorum feature bits
If the quorum does not yet all have the MONENC feature, stick to the old

It might be more polite to require a super-quorum before switching over,
and take note so that thereafter we can stick to the new encoding, but
that has more moving parts and I'm not sure it's worth the complexity.

mon: track intersection of quorum member features
When we form a quorum, also note the intersection of the quorum members'
feature bits. This will inform decisions about what encodings we use.
This is an imperfect strategy because the quorum may change, and we may
have a mon with old code join in and not understand what is going on.
However, it does ensure that a majority of the members run new code, so in
the absence of other failures we can make progress.

PG: improve find_best_info
07f853db3982e68b952a337cf91cbf7ec0709de9 is actually too conservative,
it suffices to find any info with a last_update of at least the least
last_update from the last period to go active. An info from a previous
interval is acceptable if the last interval never reported a commited
operation and thus still has the same last_update.

Makefile: link gtest statically
The problem:
- the unittests link against gtest, and gtest is not installed. that's
normally fine, but...
- rbd and rados api unit tests link against gtest, and are installed
by 'make install'. they are needed for teuthology runs, etc.
- if we build gtest as an .la library, we can only control whether *all*
or *no* .la libraries are linked statically.
- we want librados to be linked dynamically.
The solution:
- build gtest as .a instead of a libtool library
- link it statically, always.
Unit test binaries are bigger now. Oh well...

PG: track purged pgs during active
See bug #2462.
The following sequence could cause a log assuming a non-empty pg
to an empty replica:
1. primary sends query to stray
2. stray sends notify to primary
3. primary sends purge to stray removing stray from peer_info
4. stray recieves query and sends a notify
5. stray recieves purge and purges its pg
6. primary recieves notify from stray and adds it to peer_info
note: peer_info[stray] is now wrong
7. acting set changes, primary is still primary, stray is replica
8. primary sends log to replica based on incorrect info from 6.
This patch adds a purged_peer set which is populated during purge_strays
and cleared during start_peering_interval. The primary will ignore
notifies from the peer once the peer is in this set.
