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.

d6649d9a3b sws: move initializing dither_error 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.

0fb014b7bb sws: reset sliceDir at the end of sws_scale() 
Makes it more clear that resetting it does not interact with the scaling
code that it is currently intermixed with.

1f80789bf7 sws: rename SwsContext.swscale to convert_unscaled 
That function pointer is now used only for unscaled conversion.

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.

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.

1200264fc4 swscale/rgb2rgb_template: use shuffle macro on big-endian arches 
Fixes fate-qtrle-32bit on big-endian.

The macro does a simple byte swap on uint8 array without any casts, so
it's valid on big-endian arches.

The mentioned test was failing because the byteswap function
shuffle_bytes_3210_c() is used in the pixel format conversion
(argb->bgra).
