There is no point in populating NuvContext with another DSPContext.

Also split static and dynamic initialization bits to avoid running the
static initialization parts over and over.

Arch-specific optimizations are handled this way everywhere else.

This gets rid of aliasing completely unrelated structs to Picture.

Fixes the remaining compilation warnings in the vdpau code.

The code passed H264Picture* and Picture*, and assumed the
hwaccel_picture_private field was in the same place in both
structs. Somehow this happened to work in Libav, but broke in
FFmpeg (and probably subtly breaks in Libav too).

This is in line with how the top-level libavcodec Makefile is structured.

This avoids recalculating the value over and over again.

This allows for a more natural macro usage.

It is not supported by all compilers on FATE. Fixes "some test were
skipped" errors.

This fixes fate-float_dsp-test on RVCT 4.0.

Only enable it for CPUs that support it.
This restores the behavior prior to 7a650caf.

The specification uses lower case most of the time.

Print the UL in code format and in the short format used by the
specification.

Some files set the PreviousPartition field to point to its own offset.

If we are parsing forward the Previous partition is immediately known
and its value could be used, otherwise we can safely point to the
header.

Unbreak some MXF Proxy files.

Ported from arm NEON and added vector_dmul_scalar.

Functions between 1.5 and 5 times faster than the C implementations
using Apple's clang-503.0.19 on A7.
