Convert doxygen to multiline and express bitfields more simply.

Those decoders have been switched to float output and so do not use
fmtconvert anymore.

These are the only WMA bits shared with binkaudio. Splitting them off
reduces the binnkaudio dependency on general WMA code.

This makes wmadec/enc, twinvq and mpegaudiodec (i.e. mp2/mp3)
independent of dsputil.

channels, sample_rate, bit_rate, and block_align can be used directly from
the AVCodecContext

ff_wma_init is used only by wmadec and wmaenc, and neither of them
can handle more than 2 channels.
This fixes crashes with invalid files.
Based on patch by Piotr Bandurski and Michael Niedermayer.

The MDCT buffers in the decoder are only sized for up to 11 bits. The
reverse engineered documentation for WMA1/2 headers say that that for
all samplerates above 32kHz 11 bits are used. 12 and 13 bit support
were added for WMAPro. I was unable to make any Microsoft tools generate
a test file at a samplerate above 48kHz.

The initial values are not checked against the number of block sizes.
Initializing them to frame_len_bits will result in a block size index of 0
in these cases instead of something that might be out-of-range.
Fixes Bug 81.

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

This will be beneficial for use with the audio conversion API without
requiring it to depend on all of dsputil.

- remove unneeded vlc code < 0 check
- reorder vlc code handling so that the unlikely escape decoding
part comes last
- move overflow check out of the decode loop
