Instead of maintaining a set of snapids that have been removed over
all time, instead note just the newly removed and newly purged snaps
in each OSDMap epoch. This is easier to consume for both the Objecter
and OSD.
Also keep the interval of snaps that have been removed but not perged
in each OSDMap. This is extremely convenient because it frees the OSDs
from having to maintain this information in parallel even when they may
not have PGs belonging to those pools. These structures will be large
right when the ugprade happens and the pg_pool_t::removed_snaps gets copied
to the new fields, but in the steady state it will be relatively small,
reflecting only the set of snaps that are currently being removed.
This also provides convenient visibility into the "trimming snaps" set
that the cluster is working on.

This ensures we don't have any cruft left over in fields that decode()
assumes are initialized from the ctor (and not a previous instance).

In reality we only call this when the PG is peered and thus past_intervals
is empty, but this is more defensive in case that changes someday!

If we are in recovery_unfound state waiting for unfound objects, and we
find them, we need to restart the recovery reservation process so that we
can recover. Do this by queueing DoRecover() event instead of calling
queue_recovery() (which won't do anything since we're not in
recoverying|backfilling pg states).
Make the parent Active state ignore DoRecovery so that if we are already
in some phase of recovery/backfill the event gets ignored. It is already
handled by the other important substates that care, like Clean (for
repair's benefit).
I'm not sure why states like Activating are paying attention tot his vevent...

* ceph.spec.in, cmake/modules/BuildSPDK.cmake, debian/control:
re-introduce libuuid dependency, as 17.07 added lvol. and the latter
depends on uuid.
* cmake/modules/BuildSPDK.cmake: avoid introducing local variable of

* cmake/modules/patch-dpdk-conf.sh: disable
CONFIG_RTE_EAL_NUMA_AWARE_HUGEPAGES, this option introduces the
balanced allocation of memory. but it also requires libnuma-dev.
let's disable it for now.
