Set category to divx4linux instead of divx (too generic).

(gst_wavparse_loop), (gst_wavparse_change_state):
* gst/wavparse/gstwavparse.h:
fix parsing of WAV files with non-standard fmt-tag size and fix
skipping of unrecognized chunks... Someone please fix this thing
to use rifflib so all this is automated.
* sys/v4l/Makefile.am:
* sys/v4l2/Makefile.am:
Add X_CFLAGS because we depend on X (for overlay).
