The init function is only compiled if MMX is enabled, the call
must use the same condition.

This moves the DWT functions from snow.c and dsputil.c to a file of
their own. A new struct, DWTContext, holds the function pointers
previously part of DSPContext.

avctx->get_buffer() in case of error, rather than AVERROR_UNKNOWN
which is deprecated, and mark AVERROR_UNKNOWN for deletion at the next
major bump.

libavutil/error.h.
Error code definitions and handling code belong to libavutil, where
they can be shared by all the libav* libraries.

Previously, the area of a lost slice would be left at the slice number of the previous
frame which could occasionally match the number of the next slice and thus a non existing
slice could have been used for prediction leading to additional decoding errors in otherwise
undamaged slices.

w53_32_c() and w97_32_c() are defined as stubs when snow encoder is
disabled. In this case, those functions are not referenced at all
and do thus not need to be defined.

These casts are correct and safe. The pointers are guaranteed to
have proper alignment, and aliasing is not a problem with character
types.

I couldn't measure it to be slower for normal interframe videos.
For the worst case, high-bitrate intra-only videos, it can be 0.7% slower.

This triggers lAPrev (e_a[0]) on the first SBR frame to be -1. The spec is
somewhat ambiguous to what this value should be but this increases the accuracy
of al_sbr_e_44_1 and similar streams from 14 bits to 15 bits.

This reduces the number of false dependencies on header files and
speeds up compilation.
