thus making it more managable.

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.

af00dddeca aacenc: Rename Psy3gpp* structs to AacPsy*
This allows cleaner implementation of other psymodels using the existing
structs. It also will make it easier to interchange individual parts of
the psymodel to create hybrid models.
