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.
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.

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.

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.

The code was written in 2012, but seems to have been broken
for just as long. Compilation is broken on every MIPS/MIPS64
system with an FPU (which the code depends on).
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.
Up until now, there was one AACDecContext for the fixed
and one for the floating point decoder. These differed
mostly in certain arrays which were int for the fixed-point
and float for the floating point decoder; there were also
differences in corresponding function pointers.
Yet in order to deduplicate the enormous amount of currently
duplicated code between the float and the fixed-point decoder,
one needs common contexts. Given that int and float have the
same size on all common systems, this commit replaces these
arrays by unions of int arrays and of float arrays. The names
of these arrays have been chosen to be compatible with
AAC_RENAME().

sizeof(PredictorState) is different for the floating-point and
the fixed-point AAC decoders; this is an obstacle for deduplicating
code between these decoders. So don't include this array in
SingleChannelElement, instead add a union of pointers to the
fixed-point PredictorState and the floating-point PredictorState.
The actual arrays are part of the extended ChannelElement
to be allocated by ff_aac_sbr_ctx_alloc_init(); it also
sets the pointers.

Up until now, AACDecContext included pointers to one of these
contexts depending upon USE_FIXED. Yet deduplicating
the common parts of the float and fixed-point AAC decoders
needs common structures, so we put both of these pointers
in a union.
