lavu: add CHK_OFFS as AV_CHECK_OFFSET to check struct member offsets
lavr: define ResampleContext in resample.h

Required for arch optimized resampling.
aarch64: NEON optimized FIR audio resampling

Optimized for the default filter length 16.

30% faster opus silk decoding.

vc1: Do not return an error when skipping b frames

This caused mpv (and possibly others) to fallback to software decoding after
seeking a VC1 stream.

lavc: eliminate tb_unreliable()

If framerate estimation is enabled, it makes sense to always apply it,
instead of limiting it to a few specific cases.
dxva2_h264: set the correct ref frame index in the long slice struct

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)

dxva2_h264: add a workaround for old Intel GPUs

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.

configure: rework dxva in avconv handling

Move the dxva check after the dependencies have been detected, make sure
the ole32 library exists.

Fixes build on non-Windows.

mpegvideo: move the MpegEncContext fields used from arm asm to the beginning

This should reduce the frequency with which the offsets need to be
updated.
mpegvideo: remove unused MpegEncContext.b4_stride
h264: drop commented out cruft
avconv_dxva2: define all used GUIDs directly instead of relying on the dxva2api.h header

This avoids issues with inconsistent headers with different versions of mingw-w64 and older MSVC variants.

Fixes FATE builds of MSVC 2010.
