This is one of the items on the RTSP TODO list and is currently
unimplemented--partially because it will be somewhat tricky to
implement (being sure not to view a response as a request and
vice-versa), and also because I wasn't aware of any servers actually
making use of this feature.

CURL_RTSPREQ_RECEIVE would definitely need to be adjusted for this,
but we'd also have to take care not to treat the case of a server
sending async request while we are waiting for a response as the
response we are waiting for.

If you'd like to take a stab at it, I'm happy to assist if I can. I'm
also willing to give the code another look and see if I can't find a
decent way of doing it, but this is all in my free time now.
