86e41bc300 aacenc: replace VLA with fixed size
Number of channels is restricted to 6 so the size is acceptable
for the stack.

4e42debc8d aacenc: Start the lookahead pointer 1/4 of the way into the first short window.
Short windows are of length 256 and begin at sample 448.

31184aac87 aacenc: Fix psy logic.
Set band info before determining scalefactors. Use the look ahead for
windowing decision.

495af353db Set cur_channel in the AAC encoder context where needed.
Most coder functions read it. Carting this around in the context may be
suboptimal; a refactor should be considered.

ba87f0801d Remove explicit filename from Doxygen @file commands.
Passing an explicit filename to this command is only necessary if the
documentation in the @file block refers to a file different from the
one the block resides in.

7d485f165f Support for getting (i)MDCT output multiplied by a constant scaling factor.
Scaling (i)MDCT output has no runtime overhead and can be used to improve
performance of audio codecs. All the changes are only needed in
'ff_mdct_init' function and slow down initialization a bit.
