This is a workaround that makes the warning go away. Not certain there
isn't something we should be changing...

After Monitor::init_paxos() has loaded all of the PaxosService state,
we should then map creating pgs to osds. This ensures we do so after the
osdmap has been loaded and the pgs actually map somewhere meaningful.

This avoids calculating new pg creation mappings if the osdmap isn't
loaded yet, which currently happens when during Monitor::paxos_init()
on startup. Assuming osdmap epoch is nonzero, it should always be
safe to do this (although possibly unnecessary).
More cleanup here is certainly possible, but this is one step toward fixing
the bad behavior for #4675.

Factor out the portion of the function that remaps creating pgs to osds
from the part that sends those pending creates out.

If we get a dup reply something is probably wrong! We should make sure
it appears more loudly in the log. In particular, it can lead to out
of sync cap state; see #4853.

A sequence like:
- ceph-fuse starts, make_request on getattr
- waits for mds to be active
- tries to open a session
- mds restarts, recovers
- eventually gets session open reply
- sends first getattr (even tho mds is in reconnect state)
- gets mdsmap update that mds is now active
- kicks request, resends getattr
- get first reply
- ignore second reply, caps get out of sync
The bug is that we send the first request when the MDS is still in
the reconnect state. The fix is to loop in make_request so that we
ensure all conditions are satisfied before sending the request. Any
time we wait, we loop, so that we know all conditions (still) pass if
we make it to the end.

Since all currently supported platforms have tcmalloc
available and it is now the default, remove broken check code
that turns it off if the package is not listed in build-depends.

The monitor may get a series of messages from the OSD that prompt it to
send incremental maps (pg_temp updates, failures, probably more). Avoid
sending the same incremental maps twice by keeping a cache of what epochs
we think the OSDs have.
This reduces monitor load, especially when the mon is a bit behind and is
getting a stream of delayed messages, and the work associated with sending
the inc maps prevents it from catching up.
