This makes the high-dpi scaling system use the screen

Implement QEglFSScreen::pixelDensity() and make it return

The integration, screen, window and cursor classes were split in Qt 5.3 under a plan
of sharing these between eglfs, the Android port and potentially other future plugins.
This never materialized.
Maintaining the artificial split is getting difficult and is prone to errors. Therefore
it is time to merge back these base classes into eglfs. The result is cleaner, smaller,
and potentially better performing code. eglconvenience is now restored to be a collection
of convenience classes instead of platform plugin bits.

Following the principle of device integrations in QtWayland and soon
xcb, a plugin interface is being introduced to gradually replace the
statically compiled-in hooks.
The interface is same as before for the time being, for compatibility
with the existing device-specific hooks.
QEglFSHooks is now just a dummy subclass for QEGLDeviceIntegration to
support the legacy, compiled-in, device-specific hooks. When -device
is not used with configure and so there is no hook active, the new
plugin-based approach kicks in.
The environment variable QT_QPA_EGLFS_INTEGRATION can be set to
indicate the preferred integration name (e.g. eglfs_x11, eglfs_kms).
It can also be set to "none", indicating that no plugins should be
considered and the default, non-specialized integration is to be used.
(this is for devices, like Beagleboard|bone, that do not need any special
code to set up EGL)
Device makespecs can set EGLFS_DEVICE_INTEGRATION. The value is then used
as the default, preferred plugin name when QT_QPA_EGLFS_INTEGRATION is not
set. In the future device makespecs are expected to set a plugin name instead
of relying on the traditional EGLFS_PLATFORM_HOOKS_*.
When neither the QT_QPA_EGLFS_INTEGRATION nor EGLFS_DEVICE_INTEGRATION are
set, all plugins will be tried in an unspecified order. The first one that
succeeds to load is used. If all fails or there are no plugins, the built-in,
non-specialized integration is used.
To debug what integration is being used, enable the logging category
qt.qpa.egldeviceintegration.
There is some built-in logic for desktop/Mesa based systems: Under X,
eglfs_x11 is preferred, otherwise eglfs_kms is prioritized. This, assuming
sufficient permissions to video and input devices, allows simply launching
apps with -platform eglfs. No more editing of eglfs.pri.
[ChangeLog][QtGui] Added support for device-specific backend plugins in eglfs.

The cursor implementation is generic GL(ES) code that should be shared
by all the present and future egl-based embedded platform
plugins. Follow the pattern of QEGLPlatformContext and move this class
into eglconvenience as QEGLPlatformCursor.
Similarly, the common bits from the context implementation context are
moved back to EGLPlatformContext.
eglconvenience has now base classes for integration, screen, window,
etc. too. By using these, eglfs becomes much smaller and cleaner. This
also paves the way for creating new, separate EGL-based platform
plugins for Android, embedded Linux, etc.
Also added some documentation to each of the base classes.
devicediscovery is now fixed to be usable on any platform. The
implementation in this case is naturally a dummy one. This finally
allows using it from anywhere without myriads of ugly ifdefs.

Currently the mouse cursor is shown by default and it can be
turned off by setting QT_QPA_EGLFS_HIDECURSOR to a non-zero
value. This is now enhanced with an automatic detection step
via QDeviceDiscovery (the helper the input code use anyway).
From now on if QT_QPA_EGLFS_HIDECURSOR is not set, the cursor
is shown only if a mouse device is present in the system.
This could later be enhanced further by showing and hiding the cursor
dynamically during runtime although that will not be of much use for
embedded platforms without libudev.

Allow widget apps with popups and multiple top-level widgets to

Instead of trying to create a native window and EGL surface for each
window, do it only for the window that is created first. This first
window is forced to fullscreen as usual. Later windows however are
treated differently: These will not have a native window, surface or
context, and keep their normal size. All the textures belonging to the
raster windows are then rendered in one step, using a stacking order
maintained based on visibility changes and window activation.
Note that this will only help apps that create a main window first and
have everything else inside that window or on top of it as menus,
dialogs, popups, etc.

There are two problems with the current design:
1. if (hooks) hooks->foo() doesn't work in debug mode when no platform hook
is defined. The problem doesn't arise in release mode because the compiler
optimizes away the if (hooks) into a no-op since hooks is NULL when no
platform hook is defined.
2. Adding a new hook requires changing every platform's hook implementation.
New approach:
1. Define QEglFSHooks as a class with virtual functions. A stub file provides
the default implementation.
2. Platform hooks derive from above class and reimplement whatever is needed.
The filenames and variables have been changed to be more in line with the
Qt style.
