This introduces the ability to indirectly invoke all common GL1-GLES2
functions via QOpenGLFunctions. The GL1 functions are not yet resolved,
since this would not work anyway when linking to an OpenGL implementation
directly. However this may change later but that will be a completely
internal change without affecting any public APIs.
Also migrate some of the opengl examples to use QOpenGLFunctions for
everything. Once dynamic GL loading becomes available on some platforms,
these examples should continue to function without any changes since they
do not anymore invoke any OpenGL functions directly.

Remove the opengl proxy for now. Later it will either be moved into
a separate library or replaced by a QOpenGLFunctions-based approach.
This means that the -opengl dynamic configuration is not usable
for the time being. The rest of the enablers remain in place.
The convenience function QOpenGLFunctions::isES() is now moved to
QOpenGLContext and is changed to check the renderable type. This is
extremely useful since besides supporting dynamic GL it solves also
the problem of GL_ARB_ES2_compatibility (i.e. it triggers the real ES
path when creating an ES-compatible context with a desktop OpenGL
implementation).

Besides serving as an example for performing OpenGL rendering inside
a window container in a way that it works across all GL versions,
this is an extremely useful tool for developers and users alike
since it allows quick and easy checking of what sort of context a
particular driver returns for a particular QSurfaceFormat.
NB! Depending on the OpenGL driver, some surprises can be expected.
The handling of core/compatibility profiles, the fwdcompat bit,
the supported GLSL versions, etc. tend to be somewhat different
across the different OpenGL implementations.

The patch introduces a new build configuration on Windows which
can be requested by passing -opengl dynamic to configure.
Platforms other than Windows (including WinRT) are not affected.
The existing Angle and desktop configurations are not affected.
These continue to function as before and Angle remains the default.
In the future, when all modules have added support for the dynamic
path, as described below, the default configuration could be changed
to be the dynamic one. This would allow providing a single set of
binaries in the official builds instead of the current two.
When requesting dynamic GL, Angle is built but QT_OPENGL_ES[_2] are
never defined. Instead, the code path that has traditionally been
desktop GL only becomes the dynamic path that has to do runtime
checks. Qt modules and applications are not linked to opengl32.dll or
libegl/glesv2.dll in this case. Instead, QtGui exports all necessary
egl/egl/gl functions which will, under the hood, forward all requests
to a dynamically loaded EGL/WGL/GL implementation.
Porting guide (better said, changes needed to prepare your code to
work with dynamic GL builds when the fallback to Angle is utilized):
1. In !QT_OPENGL_ES[_2] code branches use QOpenGLFunctions::isES() to
differentiate between desktop and ES where needed. Keep in mind that
it is the desktop GL header (plus qopenglext.h) that is included,
not the GLES one.
QtGui's proxy will handle some differences, for example calling
glClearDepth will route to glClearDepthf when needed. The built-in
eglGetProcAddress is able to retrieve pointers for standard GLES2
functions too so code resolving OpenGL 2 functions will function
in any case.
2. QT_CONFIG will contain "opengl" and "dynamicgl" in dynamic builds,
but never "angle" or "opengles2".
3. The preprocessor define QT_OPENGL_DYNAMIC is also available in
dynamic builds. The usage of this is strongly discouraged and should
not be needed anywhere except for QtGui and the platform plugin.
4. Code in need of the library handle can use
QOpenGLFunctions::platformGLHandle().
The decision on which library to load is currently based on a simple
test that creates a dummy window/context and tries to resolve an
OpenGL 2 function. If this fails, it goes for Angle. This seems to work
well on Win7 PCs for example that do not have proper graphics drivers
providing OpenGL installed but are D3D9 capable using the default drivers.
Setting QT_OPENGL to desktop or angle skips the test and forces
usage of the given GL. There are also two new application attributes
that could be used for the same purpose.
If Angle is requested but the libraries are not present, desktop is
tried. If desktop is requested, or if angle is requested but nothing
works, the EGL/WGL functions will still be callable but will return 0.
This conveniently means that eglInitialize() and such will report a failure.
Debug messages can be enabled by setting QT_OPENGLPROXY_DEBUG. This will
tell which implementation is chosen.
The textures example application is ported to OpenGL 2, the GL 1
code path is removed.
[ChangeLog][QtGui] Qt builds on Windows can now be configured for
dynamic loading of the OpenGL implementation. This can be requested
by passing -opengl dynamic to configure. In this mode no modules will
link to opengl32.dll or Angle's libegl/libglesv2. Instead, QtGui will
dynamically choose between desktop and Angle during the first GL/EGL/WGL
call. This allows deploying applications with a single set of Qt libraries
with the ability of transparently falling back to Angle in case the
opengl32.dll is not suitable, due to missing graphics drivers for example.
