This function is called with only 8-byte alignment from
imdct for size 16.  The fft4 function is not called for
the larger FFT or MDCT sizes, so this has no impact on
typical uses.

Set the frame size when decoding DTS audio.

This has the side effect of fixing the computation of timestamps for DTS-HD in compute_pkt_fields.  Since frame_size is
not currently set, the duration of a frame is being guessed based on the streams bitrate.  But for DTS-HD, the bitrate
currently used is the rate of the DTS core which is much different than the whole DTS-HD stream and leads to a wildly
inaccurate frame duration estimate.

Change the test program to output text instead of binary files so
it can be compared easily in FATE.

filter_mb_fast assumed that qscale_table was padded like many of the other tables.

The reference function can be inferred from the direction of the
transform, no need for storing it with each entry.

IDCTs are partially evaluated according to IEEE 1180-1990 (more or
less).  An override is added to the table for implementations known
to not meet the spec requirements.  These variants are run but not
checked for accuracy.

Faster H.264 decoding with ALLOW_INTERLACE off.

Aliasing avoidance and general cleanup.

Avoid aliasing, unroll loops, and inline more functions.

Reduce aliasing problems and unroll mv/ref loop.

Significantly faster deblocking in streams with lots of slices.

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.
