I'm still working on the rest, but you can review and comment on it. I've
done a number of changes from the submitted here. I guess the idea is that
iterations on the wiki can be faster? The changes done to the protocol:

 Removed Reconnect - doesn't scale easily, the same work should be done
  by whomever is initiating the migration, or via other mechanisms (i.e.
  spice)
 Added Flush/FlushComplete - still need to be able to tell client to wrap
  up the outstanding operations in any way. I'm planning on implementing
  this using register_savevm_live.
 Fixes suggested by you - set the enum, removed _ from surrounding #ifdef
  (btw - why does no one use #pragma once? IIUC it's supported by gcc?)

The major issue I haven't tackled yet is the thread removal in 
ccid-card-emulated.c
is that a blocker for integration? Can it be tackled later?
