gst-libs/gst/rtp/: Added new file and header to deal with payload info.
Original commit message from CVS: * gst-libs/gst/rtp/Makefile.am: * gst-libs/gst/rtp/gstrtppayloads.c: (gst_rtp_payload_info_for_pt), (gst_rtp_payload_info_for_name): * gst-libs/gst/rtp/gstrtppayloads.h: Added new file and header to deal with payload info. * gst-libs/gst/rtp/gstrtpbuffer.c: (gst_rtp_buffer_validate_data), (gst_rtp_buffer_default_clock_rate): * gst-libs/gst/rtp/gstrtpbuffer.h: Payload specific stuff is move to new headers. Implement _default_clock rate using the new payload function. * gst-libs/gst/sdp/gstsdpmessage.c: (is_multicast_address), (gst_sdp_parse_line): * gst-libs/gst/sdp/gstsdpmessage.h: Add some more comments.
