From Qt 5.7 -> LGPL v2.1 isn't an option anymore, see
http://blog.qt.io/blog/2016/01/13/new-agreement-with-the-kde-free-qt-foundation/
Updated license headers to use new LGPL header instead of LGPL21 one
(in those files which will be under LGPL v3)

Running an example like hellogles3 with eglfs and the mouse cursor visible
breaks due to the cursor implementation not being aware of vertex array
objects. The cursor drawing code uses client side pointers and having a
VAO bound breaks this. Instead, the VAO should be reset to 0.
In addition, the same applies to all touched state: naive applications
doing custom OpenGL rendering expect the state to be unchanged between
frames and this is not unreasonable. So introduce saving and restoring
for all touched state, with the exception of Quick where there is no
need to waste time with this.

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.

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.

Allow widget apps with popups and multiple top-level widgets to
function on the eglfs platform. GL and Quick2 apps are not affected.
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.

Mostly straightforward, the a11y changes might look a bit drastic, but the
base class QAccessibleTextWidget was already disabled in this case, so we
have to obviously take out its sub-classes as well.

The current cursor implementation can be a bit hard to read
without hints about which methods are overriden.

The cursor is rendered on a dispmanx layer and moved
around. This approach saves us from having to update the
underlying window each time the cursor moves.
Dispmanx layers cannot be moved to negative coords. As
a result, currently it is not possible to move to a
location less than the hostpot. A future commit will
fix this problem.

The upcoming hardware cursor support for pi requires the cursor
code to render with it's own context. This is because the cursor
rendering happens in the input event (gui) thread which may be
different from the the scenegraph thread.
Currently, Qt can be informed about the current opengl context by
using QOpenGLContext::makeCurrent(). All of Qt's helper OpenGL
classes complain if that function has not been called. Usage of
makeCurrent API requires a QSurface. A big rewrite of EGLFS is
needed to make such a QSurface (QEglFSWindow) available to the
cursor code. There is no other way around this since Qt
has no other API to inform it that an opengl context is active.
The solution is not use Qt's OpenGL helper classes and use GL API
directly.
