RGB32(AV_PIX_FMT_BGRA on intel platforms) format may be used as overlay with alpha blending.
So add AV_PIX_FMT_BGRA format support.

One example of alpha blending overlay: ffmpeg -hwaccel qsv -c:v h264_qsv -i BA1_Sony_D.jsv
-filter_complex 'movie=lena-rgba.png,hwupload=extra_hw_frames=16[a];[0:v][a]overlay_qsv=x=10:y=10'
-c:v h264_qsv -y out.mp4

Rename RGB32 to be BGRA to make it clearer as Mark Thompson's suggestion.

V2: Add P010 format support else will introduce HEVC 10bit encoding regression.
    Thanks for LinJie's discovery.

Fixes ticket #7441.

for block contrast calculate, the block is like this:

|<---------------- stride-----------------------|
+----------------------------------------------->  X
|
|            w = 16
|    (cx,cy)+------+
|           |      |
|h=blocksize|      |
|           |      |
|           +------+
V

Y

so we calc the block contrast use:
   (cy + y) * stride + (cx + x)

yae_set_tempo was overlooked when max tempo limit was raised to 100.

tested with:
./ffmpeg_g -i Delerium/SemanticSpaces/Gateway.mp3 \
-af asendcmd=f=asendcmd.cfg,atempo=1.0 -y /tmp/asendcmd-atempo.wav

where asendcmd.cfg was:
15.0-45.0 [enter] atempo tempo 2.0,
          [leave] atempo tempo 0.5;

60.0-300.0 [enter] atempo tempo 4.0,
           [leave] atempo tempo 1.0;
