Subject: split kernel/ up according to the future library split

Create a guikernel/ directory that contains the files that'll go
into libQtGui. What remains in kernel/ will go into QtWidgets.
In addition to that image/, painting/ and text will end up
int QtGui.

+
+    \brief The QPlatformScreen class provides an abstraction for visual displays.
+
+    Many window systems has support for retrieving information on the attached displays. To be able
+    to query the display QPA uses QPlatformScreen. Qt its self is most dependent on the
+    physicalSize() function, since this is the function it uses to calculate the dpi to use when
+    converting point sizes to pixels sizes. However, this is unfortunate on some systems, as the
+    native system fakes its dpi size.
+
+    QPlatformScreen is also used by the public api QDesktopWidget for information about the desktop.
