Alex Converse 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.

change properly but this is still a good sanity check.

Alex Converse 52401b82bd mov: Don't av_malloc(0).

zero when alignment is greater than 16.
