ca32f7f208 H.264: eliminate non-transposed scantable support. 
It was an ugly hack to begin with and didn't give any performance.

NOTE: this patch opens up some future simplifications to be made (such as
removing some of the scantables from H264Context) but doesn't take advantage
of them yet.

fixed-point and floating-point AC-3 encoders.

ac05f9030e Convert floating-point MDCT coefficients to 24-bit fixed-point all at once 
instead of doing it separately in 2 different functions.
This makes float AC-3 encoding approx. 3-7% faster overall.
Also, the coefficient conversion can now be easily SIMD-optimized.
