Otherwise, we see a different object_info_t depending on whether the
transaction deleting the object clears before another op recreating it appears.
In particular, we use oi.version to set the prior_version on the log entries in
finish_ctx. If the oi is allowed to stick around the recreation log event will
have a prior version of the deletion event when it should have a prior version
of eversion_t().

For erasure pools, these may not match.
In the case of #7652, this caused pg_create messages to be send
indefinitely. register_pg() added it to the list for acting_primary, and
when we got the (non-creating) pg stat update we removed it from the list
for acting[0].

The check for OSD features may race with the boot of an OSD that does not
have the necessary features. Check the pending info too, and if there is
a missing feature, return -EAGAIN. In the callers, wait on -EAGAIN.

Make sure all running OSDs support the feature before we start using it
(even if the config option is on!).

'rados cppool' copies the contents but that doesn't make the destination
pool an unmanaged snaps pool. Therefore, we must get an ENOTSUP when
we try to remove an unmanaged snap from a not-unmanaged pool.

Although we should allow creating unmanaged snaps on not-unamanaged pools,
as long as those pools don't have any managed snapshots in them, we cannot
allow removal -- because the pool will not have any unmanaged snapshots.

We had an old invariant that agent_queue would have at least 1 entry in
it to simplify some other code paths, but it turns out that it is simpler
not to do that.
In particular, this was triggering a failed assertion on shutdown when we
assert that the queue is empty.
Dump offending items on shutdown if they are there, tho, to catch any
future bugs.

Each upstart/*-all-starter.conf use the same script to find the list of
daemons and their ids. Copy it over to the corresponding logrotate.conf
script instead of using a less reliable script based on initctl list
output.
If logrotate fails to run initctl reload on a daemon, it will keep
writing to the rotated log file, even after it is deleted and until it
fills the disk. By using the exact same shell snippet as the upstart
scripts used to start the daemon, all of them will be sent the HUP
signal and reopen the log file that was just rotated.

This wreaks havoc on our QA because it marks osds up and down and then
immediately after that we try to scrub and some osds are still down.
Adjust the CLI test to wait for all OSDs to come back up after thrashing.

Previously, a _delete_head() followed by a recreation on an object in
the same transaction would result in num_dirty being decremented in
_delete_head() without the flag being cleared. make_writeable() would
then see exists and was_dirty and therefore not increment num_dirty
resulting in a mismatch. Rather than trying to maintain the num_dirty
number in _delete_head(), rollback_to(), and make_writeable(), it seems
simpler to do the adjustment once in make_writeable based on undirty,
ctx->obc->obs.oi, and ctx->new_obs->oi.
