Recent versions of Python contain a change to thread shutdown that
causes ceph to hang on exit; see http://bugs.python.org/issue21963.
As it turns out, this is relatively easy to avoid by not spawning
threads on exit, as Rados.__del__() will certainly do by calling
shutdown(); I suspect, but haven't proven, that the problem is
that shutdown() tries to start() a threading.Thread() that never
makes it all the way back to signal start().
Also add a PendingReleaseNote and extra doc comments to clarify.

OSDs will now rely on 'leveldb_*' config options. We do keep however
leveldb's log enabled for OSDs by passing 'leveldb_log=""' as a default
argument to global_init() on ceph_osd.cc -- however, users will be able
to override this at their own discretion.

'leveldb_*' options are currently used both by the monitor and the osd.
However, the monitor has quite different requirements from those of the
osds.
We need to specify some default values that must squash the defaults we
have for 'leveldb_*' options, while allowing users to overriding them too.
We take this not-exactly-ideal-but-still-good-enough approach of
defining the monitor-specific defaults in the 'default arguments' to
global_init(), thus allowing the user's options to take precedence over
whatever we define.

From this point onward, users should use leveldb's options and add them
to the appropriate config sections of their configuration file.

A 'status' or 'health' request will return a HEALTH_WARN whenever the
monitor handling the request has the option set to zero.

The FileStore's leveldb currently uses libleveldb's defaults for cache and
write buffer size, which are both 4 MB. Increase the cache size to 128MB and
the write buffer to 8MB.

Reading past the end of a pointer returned by string.data() in c++98
is undefined. While we're fixing this, also allow comparison of xattrs
containing null bytes.

Just before sending an op, prepare_mutate_op() is called, creating a
new Op. prepare_read_op() already copied over all the out-params
correctly, but for write operations the individual op return value
pointers were not copied, so they would not be filled in. With this
fixed, librados users can get the per-op return codes again.

Require that all OSDs support TMAP2OMAP before starting the MDS. This
avoids doing some work and then crashing with EOPNOTSUPP, and gives us
a more informative message in the logs.

rbd_list will return -ENOENT when no rbd_directory object
exists. Handle this in the cli tool and interpret it as success with

Add this to the release notes since it changes command line behavior.

--osd-pool-default-crush-replicated-ruleset replaces
--osd-pool-default-crush-rule
If --osd-pool-default-crush-rule is set it takes precedence over
--osd-pool-default-crush-replicated-ruleset and a deprecation warning is
displayed.
The CrushWrapper::get_osd_pool_default_crush_replicated_ruleset helper is
used to implement this behaviour.
