implement fake guest thread in client/server live migration sample (#264)
* add fake guest thread in migration sample
This patch adds a thread that pretends to be the guest VM (while the
client itself is the VMM) in the live migration sample. Our goal is to
have the fake guest modifying device state while live migration is
ongoing and when live migration has finished the device state should be
correct in the destination server.
Currently this doesn't work because the server blindly applies device
state when resuming, which is wrong because some device state must be
applied to specific offsets. To fix this we have to include the offset
and length (along with BAR1 data) in the migration stream.
