Re-work the vcl aspects of the iOS port

Don't try to use similar code as for OS X to manage windows, events
etc. I.e. don't use UIKit in vcl to do that. Instead, just do as in
the Android port, use the "headless" vcl backend. Do keep using
CoreText, though, not FreeType & fontconfig.

Start changing the iOS "Viewer" app to correspond to the Android
"desktop" app (so it should be renamed).

Work in progress since a long time, several crucial details still
missing, but committing for now.

-   sadly there seems to be no way to impose clipping on a child view,
-   especially a QTMovieView which seems to ignore the current context
-   completely. Also there is no real way to shape a window; on Ios a
-   similar effect to non-rectangular windows is achieved by using a
-   non-opaque window and not painting where one wants the background
-   to shine through.
-
-   With respect to SalObject this leaves us to having an NSClipView
-   containing the child view. Even a QTMovieView respects the boundaries of
-   that, which gives us a clip "region" consisting of one rectangle.
-   This is gives us an 80% solution only, though.
