Similar to --add-item, except it will move, rename, or reweight the item if
it is already present in the map.

This is similar to insert_item(), except it will succeed if the item is
already there, and will move an item to the specified location if it is
not. It returns 0 for no change, 1 if a chance was made. It also makes
sure the weight and name match.

The check_item_loc() method will take an item and position and tell you if
it matches the items current location. The matching is identical to that
used for insert_item, in that a specific location constraint match means
success, even if a less specific one does not match (e.g., rack=wrongrack,
host=correcthost will return true).

Fixes bug #2369. The problem was that sometimes we send the
notification with the un-normalized bucket/obj pair. We
should make sure that we use the caonical name before doing
any cache update.

Make the osd create command idempotent by providing a uuid. If you call it
multiple times with the same (or some other existing) uuid you'll get back
the osd id that is already using it.
Drop support for 'osd create <id>', which was mostly useless and
non-idempotent anyway.

We may want to make this more strict, so that if it is defined it has to
match the map, and only fill it in when the map's uuid is still zeroed
(for legacy clusters)...

Rev the extended section of the map to store it. Dump it when the osd
exists. Zero it out if an osd is destroyed. Provide some accessors to
identify an osd given a uuid (linear search).

This only affects the decision to queue or do things inline, so it is safe
to change while the filestore is up and running.
Also adjust the #ifdef so that there we share a single path through the
code when sync_file_range() is missing.

If only want to include down osds if *all* of the prior acting osds are
down. If osd->whoami is one of them, then we're okay.
For example, if osd.13 is down, then the below should be satisfied that
osd.14 (osd->whoami) is alive:
