[PATCH 1/5] winegstreamer: Rename gstdemux_source to parser_source.

"gstdemux" is not a very specific name, or accurate (it does not always demux,
nor is it the only object which may demux using GStreamer). Also, while it
does not risk colliding with GStreamer definitions as-is (lacking an
underscore), I am inclined to avoid using "gst" or "gstreamer" as a prefix for
our definitions, simply for the sake of clarity.
"parser" is the common term for both DirectShow filters and GStreamer elements
which "drive" the pipeline, i.e. explicitly pull data from upstream and push
data downstream. While it's arguably still not specific enough (i.e. should be
specifically identified as a DirectShow parser), I think that the differing
terminology in Media Foundation (where the counterpart is a "media source")
makes the choice of a shorter name justifiable.
