Jon TURNEY f57100bb36 hw/xwin: Process one Windows message per wakeup, rather than all of them. ...

De-queuing Windows messages and X events happens in the same thread of
execution.  Draining the windows message queue can lead to the X event queue
overflowing if lots of those windows messages cause X events (e.g. if a keyboard
macro program has just dumped thousands of keypresses into the Windows message
queue).  See the mailing list thread [1] for more details.

Processing one Windows message per wakeup, rather than all of them gives the X
server a chance to do stuff as well after each message.
