Víctor Manuel Jáquez Leal 8b36e25f47 Removal of gstreamer-1.0 support
The support for GStreamer 1.0 has been obsoleted in 0.5.10 release.
GStreamer 1.2 is the a minimal requirement for building the gstreamer-vaapi.

This patch removes all the pre-processor conditional code compilation guarded
for gstreamer-1.0.

Thus, all the video converters were removed too.
