24efdea7fd aacenc: Fix number of coefficients used in a LFE channel. 
The spec states:

 *  Only the lowest 12 spectral coefficients of any LFE may be non-zero

We were using the 12 lowest *bands*.

51a1d4d94a aacenc: Fix a segfault with grouped psymodel. 
10l: Forgot about TYPE_LFE being after TYPE_CPE. Which causes a
segfault when encoding 5.1

ec6402b7c5 lavc: use designated initialisers for all codecs. 
It's more readable and less prone to breakage.

98add74e85 aacenc: Fix determination of Mid/Side Mode. 
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.

cc9947ffbe aacenc: Add stereo_mode option. 
ms_off is the default, until Mid/Side is no longer buggy.

230c1a9075 aacenc: Finish 3GPP psymodel analysis for non mid/side cases. 
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.

4538729afe Move sine windows to a separate file 
These windows do not really belong in fft/mdct files and were
easily confused with the similarly named tables used by rdft.

a45fbda994 Move ff_kbd_window_init() to a separate file 
This function is not tightly coupled to mdct, and it's in the way
of making a fixed-point mdct implementation.

31ff9bd7b8 aacenc: Fix a segfault in search_for_quantizers 
This reverts the removal of scoefs from AACEncContext.
It resulted in scoefs being a NULL pointer when
search_for_quantizers() is called.
