2c05ee092b avutil/internal, swresample/audioconvert: Remove cpu.h inclusions 
These inclusions are not necessary, as cpu.h is already included
wherever it is needed (via direct inclusion or via the arch-specific
headers).
Also remove other unnecessary cpu.h inclusions from ordinary
non-headers.

fa1e158ef6 swscale/utils: Use full chroma interpolation for rgb4/8 and dither none 
Dither none is only implemented in full chroma interpolation for these rgb formats
Its also a obscure choice (producing less nice images) that implementing it in the
other code-paths makes no sense

37c0fe49b7 sws: move updating the palette higher up 
It does not interact in any way with the code setting up the image
pointers/strides, so it should not be intermixed with it.

e188985598 sws: move the early return for zero-sized slices higher up 
Place it right after the input parameter validation. There is no point
in performing any setup if the sws_scale() call won't do anything.

1f80789bf7 sws: rename SwsContext.swscale to convert_unscaled

fe490ec165 sws: separate the calls to scaled vs unscaled conversion 
Call the scaler function directly rather than through a function
pointer. Drop the now-unused return value from ff_getSwsFunc() and
rename the function to reflect its new role.

This will be useful in the following commits, where it will become
important that the amount of output is different for scaled vs unscaled
case.

f3c197b129 Include attributes.h directly

yet said file won't use include it any more after the currently
deprecated functions are removed, so include attributes.h directly.

c23a5523b5 swscale/x86/swscale: Remove unused ASM constants 
The last user of g15Mask, r15Mask, g16Mask and r16Mask was disabled
in 77a416e8aa and finally removed in
36e8de07ed62609df45d064b56501e3084d25723; b15Mask and b16Mask were
apparently always unused (except for in_asm_used_var_warning_killer,
a function that only existed to make the compiler not optimize ASM
constants away).
w10 is unused since d604bab901, w02
since ef423a6618.
