mgcp/rtp: Add more test cases for RTP header patching
This patch extends the existing RTP error check test by adding a
check for timestamp errors after SSRC changes and a check for a
segno delta of 2 (with a timestamp delta of 320).
To test SSRC patching too, a corresponding line will be written on
each SSRC change that has been detected in the output stream.
In addition there is now support for selectively enabling/disabling
SSRC and timestamp patching. The RTP test sequence is repeated for
all combinations thereof.
