gst-plugin: Allow the instantiation/configuration of multiple plugins

Kevin Pouget requested to merge kpouget/spice-streaming-agent:rev/multi-gst into master

This patch allows the instantiation and the configuration of multiple GStreamer plugins from the commandline.

One plugin will be instantiated for each gst.codec=VALUE found in the command line arguments.

A plugin can be instantiated by codec, with the default gstreamer encoder: gst.codec=CODEC_TYPE (eg, mjpeg/vp8/vp9/...), or with a codec and an encoder gst.codec=CODEC_TYPE=ENCODER.

A plugin can be configured in different ways (see WantOption()):

  • without prefix (eg, framerate=30) for all the plugins,
  • with the GStreamer property prefix:
    • gst.prop=VALUE for all the GStreamer plugins,
    • gst.CODEC_TYPE.prop=VALUE for all the GStreamer plugin using the given codec type,
    • gst.ENCODER.prop=VALUE for the GStreamer plugin using the given encoder.

The split between ParseOptions and UpdateOptions will later allow live plugin reconfiguration (ie, without fully relaunching the spice-streaming-agent).
