Remove an unneeded inner loop in adjust_frame_information that
had no effect, the loop body can be run only once and will compute
the same max sfb.

aacdec: avoid generating unused code when either implementation is disabled 
Minor optimization to remove extra branches.
We need to include the header for xHE anyway, which is float-only.

opusdsp: add ability to modify deemphasis constant 
xHE-AAC relies on the same postfilter mechanism
that Opus uses to improve clarity (albeit with a steeper
deemphasis filter).

The code to apply it is identical, it's still just a
simple IIR low-pass filter. This commit makes it possible
to use alternative constants.

9d675bb60d avcodec/nvenc: add high bit depth encoding for HEVC 
Adding 10-bit encoding support for HEVC if the input is 8-bit. In
case of 8-bit input content, NVENC performs an internal CUDA 8 to
10-bit conversion of the input prior to encoding. Currently, only
AV1 supports encoding 8-bit content as 10-bit.

8c62d77139 lavc/vp9: Fix regression introduced in 0ba05857 
It is possible that ff_progress_frame_await() is called but
ff_progress_frame_report() isn't called when a hardware acceleration
method is used, so a thread for vp9 decoding might get stuck.

9e49915195 avcodec/mediacodecenc: Add global header support 
The extradata is generated by encoding a dummy frame, then reset
the encoder state by mediacodec flush(). It only works for pixel
format other than AV_PIX_FMT_MEDIACODEC, since I'm not sure how
to create a dummy frame safely with AV_PIX_FMT_MEDIACODEC.

aacdec: template LTP windowing separately 
The function is called only internally in DSP, so we do not
need to expose it.

apply_ltp on MIPS uses this function, but due to the function
being just a glue function with no real optimizations,
duplicate it there.
