Víctor Manuel Jáquez Leal 6022d97edf libs: display, context: handle broken jpeg decoder for i965 driver
JPEG decoding in i965 driver is pretty much broken, and the driver is
deprecated which mean authors only accept trivial fixes.

Surfaces for JPEG decoder context in i965 only handle IMC3[1] color
format which is not a common format in GStreamer. It can export it to
I420 at mapping raw bytes, but DMABuf exporting is problematic.

This patch artificially adds NV12 to the context format list when it's
JPEG decoder for i965 and force the usage of old VA-API for surface
creation without specifying color format. Also it artificially
disables the DMABuf announcement.
