iOS: copy brute-force port of Qt4 uikit plugin into Qt5.

The plugin has been renamed from uikit to ios.
Other than that, the plugin will now build, but do nothing. Most of
the Qt4 code is preserved, with a rough translation
into the Qt5 qpa API. A lot of code has simply been commented
out so far, and most lacking at the moment is the event dispatcher
which will need to be rewritten, and the opengl paint device
implementation. But it should suffice as a starting ground.

Also: The plugin will currently not automatically build when
building Qt, this needs to be enabled from configure first.
