Move vector_fmul() from DSPContext to AVFloatDSPContext.

This will allow for easier implementation of Altivec functions in libraries
other than libavcodec.

using as_assert() in the table generator would make the generators
have to be linked to libavutil.

This reverts commit c3b6efa4cb.

This ensures that these functions are inlined into the per-position
entry points, allowing constant propagation as needed for proper
optimisation.

Fixes yesterday's merge of Kostya's fix for ticket #409.

Duplicate values in this vector are explicitly banned by the Vorbis I spec
and cause divide-by-zero crashes later on.

This will be useful for Indeo Audio decoder which is almost the same
but supports stereo.

In Musepack SV8 codec property tell the maximum nonzero band, but every
frame codes maximum band as a limit (i.e. strictly less than given value).
Synthesis also expects maximum nonzero band, so there's a need to convert
frame maximum band limit value.

This works as expected if the input stream is not yuv4xxp.

Some demuxers set a timecode in the format or streams metadata. The
muxers now make use of this metadata instead of a duplicated private
option.

This makes possible transparent copy of the timecode when transmuxing
and transcoding.

-timecode option for MPEG1/2 codec is also renamed to -gop_timecode. The
global ffmpeg -timecode option will set it anyway so no option change
visible for the user.
