It was converted over ARGB32PM, when it should have been directly
converted to not lose accuracy, instead there was an unnecessary direct
ARGB32->RGB30 conversion, which was converted to the necessary type.
This also improves the selection of conversion over ARGB32PM or RGBA64PM
for ARGB32 and RGBA8888 by using 32-bit conversion when alpha is not
relevant.

During the creation of a raster paint engine in QImage::paintEngine(),
the QImage will be detached. At least old gcc versions would get
confused so that the newly created paintengine would end up in the old
QImage copy insteads of the newly detached one. Work around by
dropping the temporary engine pointer.

We don't need a getter for the 'preset' of a color-space, as color
spaces can be compared to the presets directly. This allows us to
remove the Undefined and Unknown values from the presets.
Internally we still distinguish known presets from unknown or undefined
presets via the magic 0-value. The validity of a QColorSpace is not
based on this preset, but on its actual values.

If QImageReader recognized the suffix of a file, it would by default
not check if the file contents matched the claimed format. Hence, a
valid but misnamed image file would fail to load.
Fix by adding contents check for suffix-recognized files.
[ChangeLog][QtGui][Image] Loading of image files having a file name
suffix for a different image file type has been fixed. QImageReader
will now ask the suffix format handler to confirm the file contents
(canRead()), and fall back to normal file content recognition on
failure. This implies a slight behavior change in
QImageReader::loopCount(), ::imageCount() and ::nextImageDelay(): For
an unreadable file with a recognized suffix, they would earlier return
0, while they now will return -1, i.e. error as per the documentation.

Rename the method systemOpaqueFormat to systemNativeFormat since that's how
it's used most of the time. And do a conversion when we actually care whether
the format is opaque or not.
