b7c96769c5 aacenc: Refactor the parts of the AAC psymodel. 
3GPP:
Remove ffac from and move min_snr out of AacPsyBand.
Rearrange AacPsyCoeffs to make it easier to implement energy spreading.
Rename the band[] array to bands[]
Copy energies and thresholds at the end of analysis.

LAME:
Use a loop instead of an if chain in LAME windowing.

79414257e2 mathops: fix MULL() when the compiler does not inline the function. 
If the function is not inlined, an immmediate cannot be used for the
shift parameter, so the %cl register must be used instead in that case.

c76374c6db Use AVERROR_EXIT with url_interrupt_cb. 
Functions interrupted by url_interrupt_cb should not be restarted.
Therefore using AVERROR(EINTR) was wrong, as it did not allow to distinguish
when the underlying system call was interrupted and actually needed to be
restarted.

This fixes roundup issues 2657 and 2659 (ffplay not exiting for streamed
content).

This is different from AVERROR(EINTR) because calls that fail with EINTR
should usually be restarted.

323e6fead0 ac3enc: do not right-shift fixed-point coefficients in the final MDCT stage. 
This increases the accuracy of coefficients, leading to improved quality.
Rescaling of the coefficients to full 25-bit accuracy is done rather than
offsetting the exponent values. This requires coefficient scaling to be done
before determining the rematrixing strategy. Also, the rematrixing strategy
calculation must use 64-bit math to prevent overflow due to the higher
precision coefficients.
