And many more.

gst-plugins-bad didn't have any explicit libvpx handling, so it would be
built with/without support for it depending on build order.

More importantly, the recent libvpx bump dropped the legacy (prefix-less)
symbols from the header file and gst-plugins-bad's handling of the non
legacy symbols was buggy.

Fix it by adding an explicit vp8 suboption and add a patch to fix (drop) the
legacy symbol handling.

[PATCH] vp8: drop buggy libvpx legacy handling
Legacy handling for older libvpx versions were added back in 2010, but this
was unfortunately buggy as these symbols are enums and not defines - So they
are never defined and the legacy symbols always used.
Now that the legacy symbols are completely removed from libvpx from v1.4.0
onwards this breaks. Fix it by simply dropping the legacy handling, nobody
should be using libvpx versions from before 2010 (or gstreamer 0.10 for that
matter) any more.
