Here is a new patch that makes the VAAPI DPB match FFmpeg short_ref[] U 
long_ref[]. This will currently fail for some clips on GMA500 because the 
driver requires some frames that are not strictly marked as "used for 
reference" in the DPB, which FFmpeg doesn't provide. However, since my 
limited testing on Windows 7 + DXVA2 shows this can work with a similar 
approach (the one implemented in MPC-HC), Intel might be looking for a fix 
in the Linux driver.

In the mean time, this is the correct way for AMD and NVIDIA drivers.
