    objecter: resend unfinished lingers when osdmap is no longer paused

    Plain Ops that haven't finished yet need to be resent if the osdmap
    transitions from full or paused to unpaused.  If these Ops are
    triggered by LingerOps, they will be cancelled instead (since
    should_resend = false), but the LingerOps that triggered them will not
    be resent.

    Fix this by checking the registered flag for all linger ops, and
    resending any of them that aren't paused anymore.

    librados: fix async aio completion wakeup

    For aio flush, we register a wait on the most recent write.  The write
    completion code, however, was *only* waking the waiter if they were waiting
    on that write, without regard to previous writes (completed or not).
    For example, we might have 6 and 7 outstanding and wait on 7.  If they
    finish in order all is well, but if 7 finishes first we do the flush
    completion early.  Similarly, if we

     - start 6
     - start 7
     - finish 7
     - flush; wait on 7
     - finish 6

    we can hang forever.

    Fix by doing any completions that are prior to the oldest pending write in
    the aio write completion handler.

    librados: fix locking for AioCompletionImpl refcounting

    Add an already-locked helper so that C_Aio{Safe,Complete} can
    increment the reference count when their caller holds the
    lock. C_AioCompleteAndSafe's caller is not holding the lock, so call
    regular get() to ensure no racing updates can occur.

    This eliminates all direct manipulations of AioCompletionImpl->ref,
    and makes the necessary locking clear.

    The only place C_AioCompleteAndSafe is used is in handling
    aio_flush_async(). This could cause a missing completion.

    ceph-fuse: create finisher threads after fork()

    The ObjectCacher and MonClient classes both instantiate Finisher
    threads.  We need to make sure they are created *after* the fork(2)
    or else the process will fail to join() them on shutdown, and the
    threads will not exist while fuse is doing useful work.

    Put CephFuse on the heap and move all this initalization into the child
    block, and make sure errors are passed back to the parent.

    osd: do not include logbl in scrub map

    This is a potentially use object/file, usually prefixed by a zeroed region
    on disk, that is not used by scrub at all.  It dates back to
    f51348dc8bdd5071b7baaf3f0e4d2e0496618f08 (2008) and the original version of
    scrub.

    This *might* fix #4179.  It is not a leak per se, but I observed 1GB
    scrub messages going over the write.  Maybe the allocations are causing
    fragmentation, or the sub_op queues are growing.

    PG: don't write out pg map epoch every handle_activate_map

    We don't actually need to write out the pg map epoch on every
    activate_map as long as:
    a) the osd does not trim past the oldest pg map persisted
    b) the pg does update the persisted map epoch from time
    to time.

    To that end, we now keep a reference to the last map persisted.
    The OSD already does not trim past the oldest live OSDMapRef.
    Second, handle_activate_map will trim if the difference between
    the current map and the last_persisted_map is large enough.
