mirror: Remove server I/O lock and dirty map

Browse Source 
Given our bitset_stream events, we no longer need to worry about
keeping track of the dirty map. This also lets us rip out the
server I/O lock from mirroring.

It's possible that we can remove the lock from client.c as well at
this point, but I need to have a bit more of a think about possible
races
