Prevent 0.6.x OSDs from talking to 0.5.x
...
The new protocol is almost compatible - it has bitmaps, but also it has
a "bitmap_length" field. It's not hard to make 0.5-0.6 OSDs and clients
compatible, but for now I just assume nobody needs it.
If I'm wrong and anybody requests to upgrade their production 0.5.x system
to 0.6.x I'll fix it.

Introduce image names and metadata storage in etcd

Each inode has: image name, parent inode number & pool, size and readonly flag
Snapshots are created by switching image name to a different inode number
while using the older inode as parent.

Fix use-after-free in keepalive_timer and rework stop_client()
...
The bug reproduced if fio was temporarily stopped with SIGSTOP
during write test and then resumed after 10 seconds. In this case
"pings" were failed for all clients and fio process crashed with
'use-after-free' in keepalive_timer. It happened because it called
stop_client while having a live iterator to the map.
