Test code to check input methods using the ibus backend
used on e.g. ubuntu. The IM code is not very sophisticated,
but enough to test that things are working.

add QPlatformInputContext to help supporting
complex text input. Communication with the
focus objects/widgets will happen slightly
different then before, through events instead of
methods one can query on QWidget.
Platform plugin creation is now moved forward in
order to have a platform plugin instance at event
dispatcher creation time.
Plugins are now responsible for implementing
PlatformIntegration::createEventDispatcher and returning
an QAbstractEventDispatcher subclass.
Switch platformsupport over to be a shared library,
which is well supported by the build system.
This requires exporting classes we use. I've done
this on OS_MAC only for now.

QtPlatformSupport is a static library. Platform plugins are meant to
link against this library to pull in dependencies such as fontengines
and convenience functions for finding the right GL configs. The linker
will only pull in the symbols used, so the size of the library doesn't
really matter
