postcopy: Transmit ram size summary word
Replace the host page-size in the 'advise' command by a pagesize
summary bitmap; if the VM is just using normal RAM then
this will be exactly the same as before, however if they're using
huge pages they'll be different, and thus:
a) Migration from/to old qemu's that don't understand huge pages
will fail early.
b) Migrations with different size RAMBlocks will also fail early.
This catches it very early; earlier than the detailed per-block
check in the next patch.
