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.
