This extends the backfill reservation system to work with log-based
recovery. The Active and RepActive states of the PG state machine are
greatly expanded to deal with the increased complexity of handling both
recovery and backfill reservations.

Otherwise, a pg might go active with a single osd in the
acting set. If that osd subsequently dies, we potentially
loose client writes. Note: it's still possible for the
acting set to exceed min_size but fail to obey the spirit
of the user's crush settings (e.g., min_size is 2, but both
osds happen to be no the sam node).

rbd ls of format-2 images was looping on the first 64 (when more than 64
were present). The key name passed to the omap layer needs to always
contain the prefix, and the "inside-the-loop next-chunk" statement
was missing the "add the prefix" call.
Also, add a test for listing 100 images, format 1 and 2.

This allows using vanity domains. A CNAME record can now
be set for the domain that would point at the rgw instance,
with or without a bucket set as a subdomain.

Fixes: #3401
The problem was that put_obj_meta() was assuming object is going
to be reset, so it was resetting the object anyway. This is not
true when dealing with the immutable multipart upload parts.

If the part that we're reading is corrupted and we end up
reading zero bytes, we need to exit, otherwise we'd just
loop forever.

Users have been seeing failures where rbd rm is half-done; could be
because of outstanding watches on the rbd_header object. The state
is that rbd_children no longer contains the child, but other pieces
remain; remove considers this a failure.
Fix: test for ENOENT from remove_child, and treat that as an ignorable
error and drive on. Simulate this in copy.sh by removing the
rbd_children object altogether, which also results in ENOENT return
from remove_child.
