Some queued patches for ram disgard cleanup, and some debug probes.
QEMU's ram disgard logic is probably a bit hard to predict because we send a
bunch of packets to notify the disgarded ranges rather than sending the bitmap.
The packets to send depending on the bitmap layout.
Initially I thought it could be a problem but in reality it's fine so far per
my initial measurement. So I'm flushing the cleanup/trace patches out because
I think they're still helpful.
Please have a look, thanks.
