Alex Converse ab2a302834 AAC: Mark predictor functions av_always_inline. 
This results in a 50% speedup on main profile with no increase in binary size.

Alex Converse ca1fa4144f AAC parser: Don't write channels, sample rate, and frame size each frame. 
Thanks to backwards compatible HE-AAC signalling these values are unreliable.

Alex Converse c4a90caae2 aac: Keep decode_band_types() from eating all padding at the end of a buffer. 
Due to a shortcoming in the AAC specification, if an all zero buffer is
fed to section data decoding it will never terminate. That means without
a buffer exhaustion check decode_band_types() will consume all input
buffer padding. Worse if a get_bits() implementation that returns zeros
when padding is exhausted is used, the function will never terminate.

The fixes that by added a buffer exhaustion check in the sectioning
decoding loop.
