Mac OSX: get the correct key code when the control key is pressed

The control key results in modifiers having Qt::MetaModifier, and then
the correct character is found in charactersIgnoringModifiers.  The
rest of the time, [nsevent characters] seems to be correct.  If we
use charactersIgnoringModifiers too much of the time, then the keycode
will be wrong in some cases even though typing is still possible.

BlackBerry: fix delayed root window posting on OpenGL

The delayed root window posting introduced by
77a06e7e6c517003 broke the OpenGL support. In that patch, the posting of
the root window is trigerred by QQnxRasterRasterBackingStore's call to
QQnxWindow::post(), that obviously does not happen when OpenGL is enabled,
therefore requiring the OpenGL context to explicitly post() the root window.

Android: Fix initial window size for raster backend

We forgot to set the ShowIsFullScreen property for the raster
engine case. OpenGL windows already did the right thing, since
the GL backend is based on eglFS. The iOS backend also has
this logic.

Fix win32-icc build: _CHAR16T is not an indication of C++11 support

The macro comes from MSVC's yvals.h header and it actually indicates
absence of C++11 support in MSVC. It is defined if
_HAS_CHAR16_T_LANGUAGE_SUPPORT isn't defined, which is a C++11 feature.

Replace win32-icc/qplatformdefs.h with the MSVC one

There have been fixes done to the MSVC qplatformdefs.h that aren't
reflected in the ICC one -- specially the inclusion of
windows.h. Since ICC is never tested, simply defer to the MSVC one and
hope it's enough.
