Move vector_fmul() from DSPContext to AVFloatDSPContext.

Save the old output configuration (if it has been used
successfully) when trying a new configuration. If the new configuration
fails to decode, restore the last successful configuration.

This changes the output order of multichannel PCE based streams.

Fixes al_sbr_cm_48_5.1.mp4.

Deprecate avcodec_decode_audio3().
Implement audio support in avcodec_default_get_buffer().
Implement the new audio decoder API in all audio decoders.

Before this, almost all module groups have been used for grouping functions
and fields in structures semantically. This causes them to not appear
properly in the file documentation and needlessly clutters up the "Modules"
index.

Additionally, this commit streamlines some spelling and appearances.

Instead, scalefactors are adjusted by the offset amount, removing the need
for sf_scale, and the MDCT scales are adjusted to compensate for the higher
scalefactors. Floating-point output will be handled by modifying the MDCT
scales.

of hardcoding 200 everywhere.

This will be beneficial for use with the audio conversion API without
requiring it to depend on all of dsputil.

For a PCE based configuration map the channels solely based on tags.
For an indexed configuration map the channels solely based on position.

This works with all known exotic samples including al17, elem_id0, bad_concat,
and lfe_is_sce.
