Read the key in the first, value in the second.

This allows to avoid pointless strdups and simplify decode_str() by
dropping two of its parameters.

While they're technically invalid, it's better to skip them and try to
read the rest of the tag.

VPX_ERROR_RESILIENT_DEFAULT and VPX_ERROR_RESILIENT_PARTITIONS weren't
defined before 4cb0ebe5b27d35ccc2a78c1d16f2622ddef21f74 (CommitDate: Tue

The inline asm added in bf5d46d8 uses the 'y' modifier which
is only supported from gcc 4.5.  This check allows building
with older compilers.

Uses 'buf' directly instead of a separate iterator variable 'in'.

Uses the native sample format for the codec instead of left-shifting all
samples by 8.

Make the code easier to read.

This fixes bind(8080): Address family not supported by protocol.

Copy the Inter 8x8 scaling list as second 8x8 matrix into DXVA2's
quantization matrix data structure instead of a potentially unset
Intra chroma scaling matrix.

Fix dxva2 decoding for some H264 samples.

There is no valid reason the user should ever send such packets in the
first place, but the documentation for CODEC_CAP_DELAY states that the
codec is guaranteed not to get a NULL packet unless that capability is
set. That isn't true without preventing this case.

The workaround needs to be enabled per PCI ID which cannot be detected inside
libavcodec. So add a flag to manually enable the alternate behavior.

Also use the post-header data size to control termination of the main
decoding loop.
