Change QOpenGLTextureBlitter to be a public API, as it was originally intended.
There are now significant external uses outside qtbase (C++ compositor examples
in QtWayland), and the API is considered proven enough.
[ChangeLog][QtGui] QOpenGLTextureBlitter, a utility class to draw textured quads,
has been made public.

From Qt 5.7 -> tools & applications are lisenced under GPL v3 with some
exceptions, see
http://blog.qt.io/blog/2016/01/13/new-agreement-with-the-kde-free-qt-foundation/
Updated license headers to use new GPL-EXCEPT header instead of LGPL21 one
(in those files which will be under GPL 3 with exceptions)

Assuming that the target is always GL_TEXTURE_2D is not going to be sufficient
when working with EGLStreams for example where GL_TEXTURE_EXTERNAL_OES is a
must. The blitter is now changed to support multiple programs so other targets
can easily be added as well in the future, if necessary.

Qt copyrights are now in The Qt Company, so we could update the source
code headers accordingly. In the same go we should also fix the links to
point to qt.io.
Outdated header.LGPL removed (use header.LGPL21 instead)
Old header.LGPL3 renamed to header.LGPL3-COMM to match actual licensing
combination. New header.LGPL-COMM taken in the use file which were
using old header.LGPL3 (src/plugins/platforms/android/extract.cpp)
Added new header.LGPL3 containing Commercial + LGPLv3 + GPLv2 license
combination

This fixes the issue that the blitter required sometimes the
texture wrapping to be repeat

The Origin for Target rect was deemed a confusing concept. The current
implementation would translate the target rect to the coordinate system
specified. However, the order and "direction" of the vertices would
always be the same. So drawing a texture in for one target rect defined in
one coordinate system would paint the texture the same way as it would
when a texture was drawn for a target rect drawn in the "opposite"
coordinate system. The point with this was that if you wanted to "flip"
the texture you would specify that with the source coordinate system.
However, this approach breaks on different levels, such as QRect has functions
which expects a top left coordinate system (ie. top() and bottom()).
In the end Qt uses a top left coordinate system, hence QWindow specifies
a top left coordinate system, and hence the api becomes easier if it is
not possible to define the coordinate system of the target viewport.

private api, but useful for 2d gui code that suddenly finds itself
needing to get a set of textures onto some fbo
I didn't want to include ARB_copy_image since it looks like its from
texture/renderbuffer -> texture/renderbuffer while this class implies
texture -> write fbo. We could wrap ARB_copy_image in QOpenGLTexture or
some other class or we can add it later.
I have not added any QOpenGLTexture functions since this class opperates
on the GLuint identifier. We can add overloads later.
