Gerd Hoffmann c80276b420 input: add trace events for full queues
It isn't unusual to happen, for example during reboot when the guest
doesn't reveice events for a while.  So better don't flood stderr
with alarming messages.  Turn them into tracepoints instead so they
can be enabled in case they are needed for trouble-shooting.
