VT: SFP: Implements interface for RTP parameters.

RTP parameters will be given to NuPlayer like below.
This is same like how setParameters() working in case of
StagefrightRecorder

 video-param-decoder-profile=1;\
 video-param-decoder-level=512;\
 rtp-param-local-ip=127.0.0.1;\
 rtp-param-local-port=1234;\
 rtp-param-remote-ip=127.0.0.2;\
 rtp-param-remote-port=4321

NuPlayer will create RTPSource.class instance as a part
of a source component of media engine if it gets RTPParams
from application layer.
