b68a05dbfa gstspu: Implement PGS rendering and alpha blending
Refactor the DVD subpicture compositing, switching it to 8-bit alpha
calculations. Reuse some of the resulting code to implement PGS
subpicture blending.

Implement parsing and collecting of composition objects properly, but
assuming a single active window and colour palette for now. I need more
PGS samples.

* gst/dvdspu/gstdvdspu.h: (GST_TYPE_DVD_SPU):
Fix up dvdspu element again after previous namespace mangling:
rename debug category variable to old name, matching that in
dvdspu-render.c, to avoid undefined symbol error when loading
the module; same for the _render function in dvdspu-render.c:
we must use the same name in both .c files; change functions
now called gstgst_* back to gst_* again; and while we're at it,
we may as well canonicalise the namespace properly, namely to
gst_dvd_spu_*.
