[PATCH] Add second DRI driver name (DRI2DriverVDPAU)

["Ибрагимов Ринат" <ibragimovrinat@mail.ru>]

libvdpau uses second DRI driver name to determine which VDPAU driver
to use. This patch will allow libvdpau choose libvdpau_i965.so on systems
with Intel GPUs, libvdpau_nvidia.so on those with nVidia ones, and so on.
I'm experimenting now with generic vdpau driver using OpenGL/VA-API,
it would be convenient to have this driver selection working without manual
driver selection.
