Add a deinterlacer plugin based on the tvtime/DScaler deinterlacer,
which was relicensed to LGPL for GStreamer and in theory provides
better and faster results than the simple deinterlace element.
Fixes bug #163578.
Ported to GStreamer 0.10 but still not enabled or included in the
build system by default because of bad artefacts caused by a bug
somewhere and as it can be only build on x86/amd64 ATM and requires
special CFLAGS. Will be fixed soon.
