When running Qt autotests on a developer machine with a high
resolution, failures occur due to either some widget becoming too
small, some rounding fuzz appearing when Qt High DPI scaling is active,
or some test taking screenshots failing to deal with device pixel
ratios != 1 in the obtained pixmaps.
It is not feasible to adapt all tests to pass on high resolution
monitors in both modes (Qt High DPI scaling enabled/disabled). It
should be possible to specify the High DPI setting per test.
Previously, it was not possible to set the Qt High DPI scaling
attributes since they must be applied before QApplication
instantiation.
Enable this by checking for the presence of a static void initMain()
function on the test object and invoking it before QApplication
instantiation.
Prototypically use it in tst_qtimer and to turn off High DPI scaling for
tst_QGL.
[ChangeLog][QtTestLib] It is now possible to perform static
initialization before QApplication instantiation by implementing a
initMain() function in the test class.

It's not actually exercised by anything in our source tree, but is
potentially useful and has been part of the documented public API for
some time. So mention that the caller is responsible for delete[]ing
its return and add a test that exercises it.

Move the modeltest autotest in the right place, and fix the
other autotests that were using it to use the version now in QtTestLib.
