cogl-gst: adds _sink_is_ready() api

Browse Source 
This adds a cogl_gst_video_sink_is_ready() for code to be able to
check if it's safe to call cogl_gst_video_sink_get_pipeline() or
cogl_gst_video_sink_setup_pipeline() without causing an error.
Normally an application can listen for the pipeline-ready signal but
sometimes a sink can be passed between components that didn't have an
opportunity to connect a signal handler, so they need a way to
directly check the status.
