Now it's a bit more robust, tagging images with profiles when they're loaded,
which then get interpreted later on by conversion functions. Just Linear RGB
and sRGB profiles at the moment, same as before.
This commit fixes Martin's problem with EXRs and Multilayer images loading/
saving too dark, and it also makes the sequence editor work correctly with it too.
Also fixes:
[#19647] gamma correction with color management is reset when resetting Curve
[#19454] 2.5: Dither does not work when Color management is enabled
NOTE: BLI_winstuff.h was meant to be a wrapper around windows.h to handle
undefining various crap that windows.h defines. Platform specific headers
should only have to be included in a few places. This reduces the number
of inclusions of BLI_winstuff.h to 16 which is a much more reasonable
number (than the 144 or whatever it used to be)
It moves targa, bmp, iris and png loading so that were not opening
2 file handles for each file, and made them like the jpeg stuff.
Also cleaned up some minor other stuff.

The padding is slightly messed up, so it produces somewhat trunkcated images
however it works. I'll try and fix it later but I have to go home now.
Its atleast usable at this stage.
I moved bmp_decode.c to bmp.c and cleaned it up a little bit.
