We need to drop the Message ref() here; the msgr owns one ref

radosgw depends on libresolv since since the commit 951c6be. So we need to
add -lresolve flags, or it cannot link right library.

Avoid using shared-state rand() when picking monitors. This way we don't
screw with library users like test_librbd_fsx that rely on srand() and
rand() being deterministic.

Starter helper will start all osds that appear in /var/lib/ceph/osd/*,
as we do with the mons and mdss.
This will only proceed if the 'ready' file is there, which is currently
only touched by ceph-disk-activate.

It is possible for rebind() to fail, in which case the OSD will go through
it's shutdown procedure and call stop(). This is simpler than trying to
avoid calling stop() when rebind() fails.
Fixes: #3504

This error left a completion that should have been attached
to the right BufferHead on the left BufferHead, which would
result in the completion never being called unless the buffers
were merged before it's original read completed. This would cause
a hang in any higher level waiting for a read to complete.
The existing loop went backwards (using a forward iterator),
but stopped when the iterator reached the beginning of the map,
or when a waiter belonged to the left BufferHead.
If the first list of waiters should have been moved to the right
BufferHead, it was skipped because at that point the iterator
was at the beginning of the map, which was the main condition
of the loop.
Restructure the waiters-moving loop to go forward in the map instead,
so it's harder to make an off-by-one error.

If the desired offset overlaps a BH, data.lower_bound() will return
the element after it, since it's indexed by the start of a range.
The confusingly similarly named data_lower_bound() method fixes this,
and returns the correct starting element.

This isn't called because it's potentially expensive, but calling it

This iterator is now reset on each run through the loop,
so there's no point in incrementing it here.

Skipping these callbacks when there's a racing write or
a gap in the results causes the original reads they represent
to never be completed. If the read falls within the range
of a BufferHead, retry all waiters no matter what.

Adding a new ops log output (into a unix domain socket).
Configuration:

rgw ops log rados : whether ops should be logged in the rados
cluster
rgw ops log data backlog : max size in MB to be accumulated
