Old Intel GPUs expect the reference frame index to the actual surface,
instead of the index into RefFrameList as specified by the spec.

This workaround should be set when using one of the "ClearVideo" decoder
devices.

The latest H.264 DXVA specification states that the index in this
structure should refer to a valid entry in the RefFrameList of the picture
parameter structure, and not to the actual surface index.

Fixes H.264 DXVA2 decoding on recent Intel GPUs (tested on Sandy and Ivy)

avformat/utils: Ensure that average fps is probed if requested by the user even if tb_unreliable() is 0

  lavc: eliminate tb_unreliable()

Conflicts:
	libavformat/utils.c

tb_unreliable() is used in several other parts of libavformat and thus isnt removed
The remaining change is a removial of a call to tb_unreliable() which would cause
a practically unconditional delay of about 1 second in startup for live streams.
I will implement what the commit message claims the change should do in the next
commit

This is thus, not merged

If framerate estimation is enabled, it makes sense to always apply it,
instead of limiting it to a few specific cases.
