It's a good idea to use IOThread instead of COLO comparing thread.
comparing thread can be completely replaced by IOThread, so this idea came.

This series of updates mainly include IOThread supports the GMainContext
event loop, then the old packet regularly check and primary/secondary network
packets compare all into the IOThread processing.

Please review,thanks.

qemu-iothread: IOThread supports the GMainContext event loop
colo-compare: Use IOThread to Check old packet regularly and
 Process pactkets of the primary
colo-compare: Update the COLO document to add the IOThread
 configuration
