util.c:
Change RecvQueue to use a stack structure for receiving the
response instead of passing in the maximum sized value for a
response message.
ckpt.c:
Change all RecvQueue users to use RecvRetry since there is no
reason to queue out of order messages.
amf.c:
Clean up RecvQueue users and pass in actual buffer instead
of "overly large" buffer which has changed because of changes
to util.c
Also cleaned up memory leak in the dispatch function.
