The color values of ppm and pgm images can be either 8 or 16 bits.
They can also be scaled to a smaller max value, and they can be
expressed either binary or ascii. For some of these permutations, Qt's
image handler lacked implementation or would decode the wrong color
value. This commit fixes that.

Qt already supports high DPI icons using the “@nx” approach, where the
device pixel ratio that the image was designed for is in the file
name. However, our implementation of the freedekstop.org Icon Theme
specification did not support the Scale directory key:
https://standards.freedesktop.org/icon-theme-spec/icon-theme-spec-latest.html#directory_layout
This meant that users creating icons via QIcon::fromTheme() did not
get high DPI support. This patch fixes that.
[ChangeLog][QtGui][QIcon] Implemented support for Scale directory key
according to Icon Theme Spec. Icons created via QIcon::fromTheme()
now have high DPI support by specifying the Scale in the appropriate

We parse the EXIF header in order to get the proper orientation, so
let's be a bit more careful in what we accept. This patch adds better
handling for reading past the end of the stream, plus it limits the
number of IFDs read (to avoid processing too much data) and deals with a
pathological case of the EXIF file format: EXIF (due to its TIFF
origins) permits the offset to the next IFD to be backwards in the file,
which means it could result in a loop or pointing to plain corrupt data.
We disallow any backwards pointers, since it seems that's what other
decoders do (libexif, for example).

Commit c5db8fc74 changed all instances of Q_WS_FOO to have the prefix
Q_DEAD_CODE_FROM_QT4 instead, to make it clearer when reading the code
that the code in question was a left-over from Qt4, when we used
Q_WS_ defines instead of Q_OS_ defines.
This worked well for cases of #ifdef Q_DEAD_CODE_FROM_QT4, but less so
for cases of #ifndef Q_DEAD_CODE_FROM_QT4, where the code was actually
unconditionally included.
To make this even clearer, the defines have been replaced by checks for
1 or 0, with a comment describing how the code used to look in Qt4. The
use of constants in the check also makes it easier for editors to parse
the condition and show visually that the code is defined out.
