e18b0b9964 livemigrate : activate xbzrle cache 
This help migrate for vm with of lot of memory access (like database)

live migration tests working:

kvm 1.2 -> kvm 1.2  (xbzrle set on both side)
kvm 1.1 -> kvm 1.2 (xbzrle on target)
kvm 1.1 -> kvm 1.1 (xbzrle not set, qmp command try to set xbzrle but fail)

failing migration

kvm 1.2 -> kvm 1.1 fail, but this is expected.

I tested with a memory benchmark running on the vm with 4GB ram

without xbzrle : migration take 10min, with many network hang
with xbzrle : migration take 1min, no hang

I display xbzrle counters for debug purpose, we can remove them later

af30308f36 we call vm_stop to target host, 
to be sure that kvm process is killed (but it should kill itself),
and deactivate volumes

I slightly modified this patch (orig. from Alexandre) so that it apply cleanly.
