The DCBZL instruction is not available for the e500v1 and e500v2
architectures, but may still be recognized by the toolchain, so we
need to explicitly disable it for these architectures.

libavcodec/lagarith.c:671:16: warning: '#' flag used with ‘%u’ gnu_printf format [-Wformat]

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.
