    Gst::SDP: add Gst::SDP::Media wrapper
    
      * .gitignore: add sdpmessage autogenerated files to ignore list
      * gstreamer/src/filelist.am: add sdpmessage to a build
      * gstreamer/src/sdpmessage.{ccg|hg}: add wrapper for GstSDPKey
        and GstSDPMedia classes.
      * tools/m4/convert_gst.m4: conversion for sdpmessage enum types
