JPEG part 6 defines CMYK support. This commit adds such support to the
JPEG plugin.
A *very* interesting discovery is the fact that Photoshop inverts the
meaning of the CMYK color channels when saving into JPEG: 0 means "full
ink", and 255 means "no ink". Most other image viewers/editors follow
the same interpretation, I imagine for compatibility.
But others, like Adobe Reader, don't (???) -- a PDF expects a DCT
encoding with 0 meaning "no ink". I am adding a SubType to the image I/O
handler to let the user choose what they want, defaulting to Photoshop
behavior.
Also, turns out that Qt was already loading CMYK files and converting
them to RGB. I don't think we should do automatic, lossy conversions (we
were not taking into account an eventual colorspace...), so I'm changing
that loading to yield a CMYK QImage.
Finally: save the colorspace, even if it's a CMYK image.
QColorSpace doesn't support anything but RGB matrix-based colorspaces.
Yet, it can load an arbitrary ICC profile, and will store it even if
it's unable to use it. We can use this fact to preserve the colorspace
embedded in CMYK images, or let users set an arbitrary ICC profile on
them through Qt APIs, and then saving the result in JPEG.
[ChangeLog][QtGui][JPEG] Added support for loading and saving of JPEG
files in 8-bit CMYK format. When loading a CMYK JPEG file, Qt used to
convert it automatically to a RGB image; now instead it's kept as-is.

The density of Q_FOREACH uses in this and some other modules is still
extremely high, too high for anyone to tackle in a short amount of
time. Even if they're not concentrated in just a few TUs, we need to
make progress on a global QT_NO_FOREACH default, so grab the nettle
and stick to our strategy:
Mark the whole of Qt with QT_NO_FOREACH, to prevent new uses from
creeping in, and whitelist the affected TUs by #undef'ing
QT_NO_FOREACH locally, at the top of each file. For TUs that are part
of a larger executable, this requires these files to be compiled
separately, so add them to NO_PCH_SOURCES (which implies
NO_UNITY_BUILD_SOURCES, too).
In tst_qglobal.cpp and tst_qcollections.cpp change the comment on the
#undef QT_NO_FOREACH to indicate that these actually test the macro.

Since setScaledClipRect will actually render only the necessary parts,
there may be insignificant differences in rounding/anitaliasing
compared to rendering the whole image first and then clipping.
Hence this autotest case would always fail. But that would not happen
in CI, since it tests qtbase without the qtsvg module, and then the
SVG tests are skipped. (For some reason, one ran into this in wayland
testing and made an exception for that, but obviously this failure has
nothing to do with wayland).
Work around the issue by converting the rendered images to 4 bpc
format, so the differences in the least significant bits get truncated
away.
