58893 decicycles in deemphasis_c, 130548 runs, 524 skips
9475 decicycles in deemphasis_fma3, 130686 runs, 386 skips -> 6.21x speedup
24866 decicycles in postfilter_c, 65386 runs, 150 skips
5268 decicycles in postfilter_fma3, 65505 runs, 31 skips -> 4.72x speedup
Total decoder speedup: ~14%
Deemphasis SIMD based on the following unrolling:
const float c1 = CELT_EMPH_COEFF, c2 = c1*c1, c3 = c2*c1, c4 = c3*c1;
float state = coeff;
for (int i = 0; i < len; i += 4) {
y[0] = x[0] + c1*state;
y[1] = x[1] + c2*state + c1*x[0];
y[2] = x[2] + c3*state + c1*x[1] + c2*x[0];
y[3] = x[3] + c4*state + c1*x[2] + c2*x[1] + c3*x[0];
state = y[3];
y += 4;
x += 4;
}

We're also doing a sync here after copying the frame to be passed
on down the pipleine. And it is also unnecessary.
I was able to demonstrate a 33% speedup removing the sync from
an example transcode pipeline.

The following are the newly added options:
arnr_max_frames, arnr_strength, aq_mode, denoise_noise_level, denoise_block_size,
rc_undershoot_pct, rc_overshoot_pct, minsection_pct, maxsection_pct, frame_parallel,
enable_cdef, enable_global_motion, and intrabc.
Also added macros for compiling for aom 1.0.0 and fixed the default values.

cbs trace qsv vps header failed due to some reasons:
1. vps_temporal_id_nesting_flag is not set but spec required it must to
be 1 when vps_max_sub_layers_minus1 is equal to 0.
2. vps_num_hrd_parameters is not set and written.
3. other issues in ff_hevc_encode_nal_vps() (fixed in pervious commit_id: 520226b683).
Reproduce: ffmpeg -hwaccel qsv -v verbose -c:v h264_qsv -i bbb_sunflower_1080p_30fps_normal.mp4 -vframes 1
-c:v hevc_qsv -bsf:v trace_headers -f null -

There are many problems of current qsv trellis option:
1. Duplicated with AVCodecContext definition
2. MFX_TRELLIS_XXX is introduced by MSDK API 1.17
Currently Without MSDK API checking thus may cause compilation issue.
3. user is inclined to enable trellis when set "-trellis 1", but
actually it is to disable since MFX_TRELLIS_OFF is equal to 1.
4. It is too complex for user to enable trellis for every frame(I/P/B).
Just simply remove the private option, and switch to the AVCodecContext
definition. Compatibility should not a big problem (except can't exact map)
since the option name is same as AVCodecContext.

The fields are deprecated in current vaapi,
setting them to 0 in old versions is fine
as FMO is not implemented.
Fixes the following warnings:

.num_slice_groups_minus1 = pps->slice_group_count - 1,
