//as long oProcessIncomingMessages is true. This boolean stays true
//as long we can register packets in JB. If JB is full this boolean
//is made false (when CheckForSpaceInJitterBuffer() returns false)
//and is once again made true in JitterBufferFreeSpaceAvailable() callback.
//We also use the input port briefly as a bidirectional port in case of
//RTSP streaming to do firewall packet exchange. So if there are outgoing
//msgs and oProcessOutgoingMessages is true then node needs scheduling.
//b) PVMF_JITTER_BUFFER_PORT_TYPE_OUTPUT - As long as:
// - there are msgs in outgoing queue
// - oProcessOutgoingMessages is true
// - and as long as there is data in JB and we are not in buffering
//then node needs scheduling.
//c) PVMF_JITTER_BUFFER_PORT_TYPE_FEEDBACK - As long as:
// - there are msgs in incoming queue and oProcessIncomingMessages is true
// - there are msgs in outgoing queue and oProcessOutgoingMessages is true
