10l: Forgot about TYPE_LFE being after TYPE_CPE. Which causes a
segfault when encoding 5.1

It's more readable and less prone to breakage.

In adjust_frame_information(), msc is incremented for each sfb in each
sub-window then compared against max_sfb which is for a single sub-window.

This resulted in frames using EIGHT_SHORT_SEQUENCE where the first few
sub-windows increment msc to a value that results in ms_mode == 2. Even
though only some of the bands are actually using Mid/Side.

aacenc: Implement dummy channel group analysis that just calls the single channel analysis for each channel.

ms_off is the default, until Mid/Side is no longer buggy.

Instead use the function pointers directly.

There is still are still a few sections missing relating to TNS (not present)
and mid/side (contains other bugs).

Overall this improves quality, and vastly improves rate-control.

These windows do not really belong in fft/mdct files and were
easily confused with the similarly named tables used by rdft.

This function is not tightly coupled to mdct, and it's in the way
of making a fixed-point mdct implementation.

This removes the rather pointless wrappers (one not even inline)
for calling the fft_calc and related function pointers.

This reverts the removal of scoefs from AACEncContext.
It resulted in scoefs being a NULL pointer when
search_for_quantizers() is called.

None of these symbols should be accessed directly, so declare them as

Most coder functions read it. Carting this around in the context may be
suboptimal; a refactor should be considered.
