libceph: handle_one_map()
Separate osdmap handling from decoding and iterating over a bag of maps in a fresh MOSDMap message. This sets up the scene for the updated OSD client. Of particular importance here is the addition of pi->was_full, which can be used to answer "did this pool go full -> not-full in this map?". This is the key bit for supporting pool quotas. We won't be able to downgrade map_sem for much longer, so drop downgrade_write(). Signed-off-by: Ilya Dryomov <idryomov@gmail.com>
