The authors permitted relicensing to LGPL a long time ago (Holger,
Loren and Jason).

Fixes regression in 836f47d34b in ICC-10.x,
since ICC<=11.0 doesn't align stack upon function calls.

This does all the actual bit counting as a final step.

nasm versions prior to 2.09 have trouble assembling some of our AVX code.
Protect these sections by preprocessor macros to allow compilation to pass.

This fixes the following error on OS/2:

Add missing multiple inclusion guards; clean up #endif comments;
add missing library prefixes; keep guard names consistent.

This format is still used by e.g. OS/2.

This separation allows these functions to be used in a cleaner
fashion from other codecs (e.g. qdm2) and simplifies creating
optimised versions of them.

Partially based on patches by clsid2 in ffdshow-tryout.
ff_float_interleave6() x86 improvements by Loren Merrit.

Arguments for variable size instructions are added to many macros, along
with other various changes. The x86util.asm code was ported from x264.

Also delete some unused deblock asm macros.

Includes AVX versions from x264.

Should fix compile on systems missing yasm/nasm.

This patch lets e.g. dsputil_init chose dsp functions with respect to
the bit depth to decode. The naming scheme of bit depth dependent
functions is <base name>_<bit depth>[_<prefix>] (i.e. the old
clear_blocks_c is now named clear_blocks_8_c).

Note: Some of the functions for high bit depth is not dependent on the
bit depth, but only on the pixel size. This leaves some room for
optimizing binary size.

Preparatory patch for high bit depth h264 decoding support.

and use in scale_coefficients() for the floating-point AC-3 encoder.

If the function is not inlined, an immmediate cannot be used for the
shift parameter, so the %cl register must be used instead in that case.

This fixes compilation for x86-32 using gcc with --disable-optimizations.

The 1-arg imul instruction cannot take an immediate argument, only a register
or memory argument.
