iOS: Let QScreen manage UIWindow and root view-controller

Instead of having the application delegate set up a UIWindow and root
view-controller, we move the responsibility to QScreen, since in a multi
screen scenario we will need one UIWindow per screen, as well as one
root viewcontroller per window.

QDebugStateSaver: Fix trailing space issues

~QDebug() removes any trailing space if autoInsertSpaces() is true.
However, if one uses QDebugStateSaver the global autoInsertSpaces might
be false, but a space was added by a custom operator<<.

Explicitly check for this in QDebugStateSaverPrivate::restoreState. Remove
any trailing space if the local state asks for adding trailing spaces, but
the original one doesn't. Add a trailing space if the local state doesn't
ask for one, but the global state does.

Xcode: Fix QMAKE_PRE_LINK dependency handling

Depending on *.o in the Xcode output dir did not actually result in a
proper dependency. In Xcode5 this didn't matter much, as the effect was
that the build phase was run every time, but in Xcode6 the phase was
skipped. We now depend on the object directory itself, which will get
its modification time updated to match any rebuilt object files.

iOS: Gracefully fail main()-renaming when link-time optimizations are enabled

We don't have a way to rename main() inside a LLVM bit-code file yet, so we
error out if we detect that LTO is enabled (which causes object files to be
written as LLVM bit-code), and inform the user about a workaround.
