[PATCHv2 0/6] support watch/notify version 2

[Douglas Fuller <dfuller@redhat.com>]

osd_client, rbd: add support for version 2 of watch/notify

Support watch/notify 2 in osd_client and update rbd for compatibility.
Map ceph_osd_event to expected watch/notify messages and store watch
and watch error callbacks. Implement CEPH_OSD_WATCH_OP_PING and
CEPH_OSD_WATCH_OP_RECONNECT. Handle CEPH_WATCH_EVENT_DISCONNECT.
Handle CEPH_WATCH_EVENT_NOTIFY_COMPLETE and provide a data item for
clients to consume.

v2: incorporated changes from Mike, Josh, and Ilya. Changed notify-ack
data to page vector and size instead of ceph_msg_data and other fixes.
