3bf12beae9 swscale: slightly reorder header 
I want to start grouping "legacy" functions which I tend to deprecate
together, away from the new ones.

fbfea1c644 swscale: publicly typedef struct SwsContext 
Slightly more convenient, especially for the upcoming refactor which will
turn SwsContext into a public struct.

77e6293735 arm: Consistently use proper interworking function returns 
Use "bx lr", or "pop {lr}", which do proper mode switching
between thumb and arm modes. A plain "mov pc, lr" does not switch
from thumb mode to arm mode (while in arm mode, it does switch
mode for a thumb caller).

This is normally not an issue, as CONFIG_THUMB only is enabled if
the C compiler defaults to thumb; but stick to patterns that can
do mode switching if needed, for consistency.

ec9985b54f swscale/internal: constify and expose ff_swscale() 
Used as an intermediate entry point for the new swscale context. The extra
constification is a consistency measure, as I want to move the memcpy of
stride and plane pointers to the functions that actually need to mutate them.

775de8c19d swscale/rgb2xyz: follow convention on image pointers and strides 
Instead of taking an int16_t pointer and a stride in halfwords, follow the
usual convention of treating all planes and strides as byte-addressed.

This does not have any immediate effect but makes these functions more
reusable without unintended "gotchas".

9d8f5141cf swscale/rgb2xyz: add explicit width parameter 
This fixes an 11-year-old bug in the rgb2xyz functions, when used with a
negative stride. The current loop bounds turned it into a no-op.

Additionally, this increases performance on highly cropped images, whose
stride may be substantially higher than the effective width.
