If an SSRC conflic is detected, new SSRC must be generated and
all RTCP statistics zeroed out. The collision is detected for every
incoming RTP packet.
This error code is used to indiciate that an ongoing process (f.ex
polling a file descriptor) was interrupted but that "a real error"
did not occur and it is safe to continue
Now each supported RTP frame types has its own handler which is called
when a new RTP frame is received. This way we can do frame type specific
operations (f.ex. merging HEVC FU frames) and return fully processed
frames to user
This change introduces new status code "RTP_NOT_READY" which indicates
to the caller that the operation did not finish (eg. we've received only
part of the frame).
