fix short block imdct.

Redundant code cleanup.
Optimized dither generation.
Minor optimization in bit allocation.
Comments.

Cosmetics, white space removal.

Originally committed as revision 9668 to svn://svn.ffmpeg.org/ffmpeg/trunk

Fix the bugs:
1. The quality of output because of incorrect windowing coefficients.
New code for window generation.

2. Dynrng values were reset where dynrng value is present in the first block,
but not in the subsequent block.

Further optimizations.

Optimization as suggested by Benjamin.

Remove more unnecessary headers.
Codec initialization changed to use name => argument notation.

Converted the window from double to float.
Now sound produced is as good as sound produced by liba52.

Reset the blksw and dithflag to 0 at the begining of each block.
Otherwise blockswitching propagates over multiple frames even if
block switching is not enabled for that frame.
Also reuse rematflg.

I realized that the bug was not in the imdct routine but in the
get_transform_coeffs.
Fixed it.
Code now uses the ffmpeg's imdct routines.
All the mplayer's ac3 samples are decoded
successfully.
Also improved downmixing.
Now all the downmixing coeffcients for channels
are normalized such that the sum of coefficients
used to construct the output for single channel
never exceeds 1.0.
