Not sure I can make this actually private and make Client::put_inode() a

client: use put_inode on MetaRequest inode refs
When we drop the request inode refs, we need to use put_inode() to ensure
they get cleaned up properly (removed from inode_map, caps released, etc.).
Do this explicitly here (as we do with all other inode put() paths that
matter).

osd: tolerate racing threads starting recovery ops
We sample the (max - active) recovery ops to know how many to start, but
do not hold the lock over the full duration, such that it is possible to
start too many ops. This isn't problematic except that our condition
checks for being == max but not beyond it, and we will continue to start
recovery ops when we shouldn't. Fix this by adjusting the conditional
to be <=.

common/pick_addresses: behave even after internal_safe_to_start_threads
ceph-mon recently started using Preforker to working around forking issues.
As a result, internal_safe_to_start_threads got set sooner and calls to
pick_addresses() which try to set string config values now fail because
there are no config observers for them.
Work around this by observing the change while we adjust the value. We
assume pick_addresses() callers are smart enough to realize that their
result will be reflected by cct->_conf and not magically handled elsewhere.

unit tests for PGLog::proc_replica_log
The tests covers 100% of the LOC of proc_replica_log. It is broken down
in 7 cases to enumerate all the situations it must address. Each case
is isolated in a independant code block where the conditions are
reproduced.
All tests are done on omissing and oinfo because they are the only
data structures that can be modified by proc_replica_log.
The first case is a noop and checks that only last_complete gets
updated when there are no logs.
The following case includes entries that are supposed to be ignored (
x7, x8 and xa ), however this is not an actual proof that the code
ignoring them is actually run : it only shows in the code coverage
report.
The log entry (1,3) modifies the object x9 but the olog entry
(2,3) deletes it : log is authoritative and the object is added
to missing. x7 is divergent and ignored. x8 has a more recent
version in the log and the olog entry is ignored. xa is past
last_backfill and ignored.
The other cases are a variation of the first case with minimal changes
to make them easier to understand and adapt. For instance most of them
start with a tail that is the same ( object with hash x5 and both at
version 1,1 ).
