14e93f7e8e iOS: Add screen like other platform plugins
We may add support for external displays at a later point, but for now
we follow the same pattern as the other platform plugins. Either way we
should call screenAdded() to let the platform integration know about the
screen.

c7fbff7bf2 iOS: Add required public dependencies of the CoreText font database
CoreText and CoreGraphics are available on iOS as stand-alone

umbrella framework.

Mac OS 10.8 actually introduced both as stand-alone frameworks,
but for simplicity we link to ApplicationServices, as there's
still symlinks from ApplicationServices to the real frameworks.

5b99d46b39 iOS: Link to the platform plugin and iosmain plugin and define main
Ideally we'd only have to do QTPLUGIN += ios, but this doesn't work as
we need to link with the force_load linker option. Even trying to build
on QTPLUGIN and then replace the -l line with what we need will fail, as
the prl logic in qmake which runs after all the prf files does not know
about the force_load option and will then fail to resolve dependencies
from the prl file.

Since we load the platform plugin using -force_load, there's no need to
generate a cpp file that does the plugin import.

The main wrapper is not a real Qt plugin, and doesn't have an import
function that we can call, so we link it manually instead of relying
on QTPLUGIN.

77168c03ff iOS: Make Xcode output the default for GUI applications
As long as Qt Creator does not provide any iOS integration, and the
app bundle we create using the Makefile generator is not good enough
to deploy to a device anyways, producing Xcode projects make the most
sense.

We base the decicion on whether or not the project depends
on QtGui and has app_bundles enabled. This prevents configure
tests and other tools from having Xcode projects, but allows
examples and demos to build out of the box.

Instead of setting the generator unconditionally we unset it in
default_pre so that we can detect if the user set it manually. This
means the user won't be able to inspect the MAKEFILE_GENERATOR variable
from the pro file, but this is less of a use-case then overriding the
generator from the command line or prooject file.

8cbdb25ee6 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.

dd5b437d6a qmake: Fix file paths in Xcode projects when shadow-building
The Xcode generator seems to have been written with the assumption that
writeMakeParts() would be called with the output directory as the current
directory, but that's not the case when shadow-building. Perhaps this
was changed in qmake at some point, and the Xcode generator was not
updated to reflect that.

Instead of replacing every occurance of fileFixify and other logic to
deal with paths, we just chdir into the output_dir for the duration
of the function (except when writing the 'make qmake' makefile, as
the regular makefile generator works as expected with the current
directory set to the input directory).

3cc738dfc7 qmake: Don't treat .xcodeproj directories as OUT_PWD when passed with -o
The Xcode generator creates a makefile for running 'make qmake', and the
makefile passes -o to ensure it writes to the same Xcode project. This
fails when qmake then treats -o foo.xcodeproj/project.xcproj as not only
setting the output filename, but also the output directory to foo.xcodeproj,
which results in the Xcode project trying to reference files relative
to this directory, such as '../main.cpp'.

Unfortunatly the output filename parsing happens too early for us to know
whether or not the generator is Xcode, so we just have to assume that
a certain combination of output filename and directories means we are
generating an Xcode project.

4f14b42f7d Add support for forced VSYNC using the EGLFS platform plugin.
Before a buffer swap the new QEglFSHooks::waitForVSync method is
called which looks at QT_QPA_EGLFS_FORCEVSYNC and - if that is set
and non-null - calls ioctl with the FBIO_WAITFORVSYNC request on
the framebuffer device.

This is required on some embedded platforms where the driver does not
support VSYNC yet the Kernel provides a generic implementation.

I tested this using QML_RENDER_TIMING=1 which proofs that the frame
rate for an example of mine drops from >125fps to a straight ~60fps
with a few frames that take ~33ms (i.e. 30fps) as expected for VSYNC.

To prevent excessive open/close calls on the frame buffer device
per frame, the file descriptor is now cached. To keep the QEglFSHooks
interface as clean as possible this is done via a global static in
qeglfshooks_stub.cpp and initialized and freed in platformInit and
platformDestroy.

25c9005097 OpenGL: Refactor some defines and typedefs to a common location
These will be needed by the upcoming OpenGL enablers so move them
out of qopenglfunctions.h to somewhere that any opengl related file can
access them.

22077e1609 QPA: Add interface for setting the application state explicitly
The motivation for this patch is twofold:

1: we need a way (for iOS/Android) to tell the current window to remove
focus from the focus object when the user hides the input panel.
Otherwise, if the focus object is e.g a line edit, the cursor will
continue to blink inside it, which is wrong. As it stands, telling
the active window to deactivate
(by calling QWindowSystemInterface::handleWindowActivated(0)), will cause
the whole application to deactivate if no windows are active, which
is not what we want.

2: Qt currently understands just two application states, Activated and
Deactivated. On mobile platforms we can have other states
as well, like "suspended" on iOS. So controlling the application
state should not depend on window activation, but instead be controlled
through a separate API by the platform plugin.

This patch will add the following function:
QWindowSystemInterface::handleApplicationStateChanged(Qt::ApplicationState newState)
that lets us control the application state from the plugin. This also
means that we factor out application state handling from window
activation, which also gives us a way to remove focus from a window while
keeping the application active.

To not break existing desktop platforms that relies on application
activation being tied to window activation, we need to make this API
opt-in by using a platform integration capability hint. This is not optimal, but
found necessary after investigating several other solutions.

Which states (other that active/inactive) it makes sense
to add to Qt::ApplicationState will be a topic for later patches.
