f20518568a build: Split WMA frequencies into a separate object file 
These are the only WMA bits shared with binkaudio. Splitting them off
reduces the binnkaudio dependency on general WMA code.

710bd8a33e wma: Lower the maximum number of channels to 2 
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.

d78bb1a4b2 wma: Clip WMA1 and WMA2 frame length to 11 bits. 
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.

05d1e45d1f wma: initialize prev_block_len_bits, next_block_len_bits, and block_len_bits. 
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.
