doc: Add missing documentation for osd pool get.
"osd pool set" was already documented, but the corresponding "get"
command was not. This patch adds the list of valid fields for this
command, together with short descriptions.
Thanks to Gregory Farnum for pointing out a flaw in the description
of lpl_num and lpgp_num in an earlier version of the patch.

crush: fix force to behave with non-root TAKE
If the (first) TAKE in the crush rule is not the root, see if they picked
a point somewhere beneath the appropriate part of the hierachy. If not,
continue with a normal mapping.
Previously we would simply error out in this case and map nothing.

pybind: add object locator support to pybind pool listing
list_objects returns Object(). Object therefore now has an optional
locator_key parameter which will set up the object locator on Object()

To match the HashIndex ordering, we need to sort hobject_t by the nibble

ReplicatedPG: do not ->put() scrub messages when adding to a WorkQueue.
This function is passing a reference from PG::active_rep_scrub to
the req_scrub_wq, not eliminating the reference (and the WorkQueue
doesn't grab a new reference itself, either).
The other alternative is to convert the WorkQueue to grab a
reference, but since they can cycle through the WorkQueue more than
once, and need to be ->put() outside the WorkQueue, I don't like
that option.
This should fix #1758.
Also add an assert to PG::_request_scrub_map to check on the other
possible cause of this bug (and fix the indentation).

filejournal: remove bogus check in read_entry
It is perfectly fine to read events that are older than the fs's seq from

mon: stub perfcounters for monitor, cluster
The 'mon' perfcounter is for the local daemon and is always registered.
The 'cluster' perfcounter is for cluster state, and is only registered
(and thus only shows up via the admin socket) when the current daemon is
part of the cluster quorum.
This could conceivably cause the reply ordering mismatch seen in bug
#1490. Not sure why we didn't also fix this caller when we fixed that
bug last time :).

And I change my mind.. I think this is most cleanly handled inside crush, so
we don't duplicate the same check that is generating the error with an different
