QOpenGLBuffer::map() and related helpers are becoming useless in
OpenGL ES 3.0 and up: instead of the old GL_OES_map_buffer,
glMapBufferRange, but not glMapBuffer, is now part of the standard.
On desktop GL_ARB_map_buffer_range is present by default in OpenGL 3.0
and newer.
[ChangeLog][QtGui] Added QOpenGLBuffer::mapBufferRange().

Add defaultFormat() and setDefaultFormat() statics to QSurfaceFormat.
These define the default values for the requestedFormat members of
QOpenGLContext, QWindow and QOpenGLWidget (and implicitly QOpenGLWindow,
QQuickWindow, etc.)
This replaces QQuickWindow::setDefaultFormat() which can now be removed.
The main inspiration here is not the convenience (avoiding setFormat() calls
for all windows/widgets), but robustness: by setting the format once at the start
of the application, all windows and contexts, including the internal share context
used by QOpenGLWidget and QQuickWidget, will use the same format, eliminating
the possibility of failing due to trying to share between incompatible contexts.
Furthermore, since such a functionality is anyway mandatory for QQuickWindow
(due to the possibility of creating windows from QML code), extending it to
QSurfaceFormat and QOpenGLContext/QWindow is the next logical step.

This is trickier than the GLX and EGL implementations due to the
way pixel formats, windows and contexts work. Apart from some
restrictions, it should be fully functional nonetheless.

Currently QOpenGLTextureCache::bindTexture always convert any uploaded
image to RGBA8888 before uploading. This is quite inefficient when
OpenGL natively supports uploading formats in the original format.
This patch adds support for uploading a few native QImage formats. This
also get the performance of QOpenGLTextureCache::bindTexture on par with
QGLContext::bindTexture.
The texture brush used by QOpenGLPaintEngine is also converted to QImage,
since bindTexture will convert it to QImage anyway, and going over QPixmap
may cause an unnecessary conversion.
[ChangeLog][QtGui][QOpenGLTextureCache] Support uploading common QImage
formats directly to OpenGL when supported.

There is no guarantee that the OES extension is present and the standard
functions are not required to be dynamically resolvable on ES.
By performing the ARB-style lookup for the suffixless function names we
can also support ES3 compatible contexts on desktop GL.
This also fixes the problem of picking up the APPLE extension functions
instead of ARB when both are available. vaoFuncsType was set to ARB correctly
but the helper has to take the preference of ARB into account too.

When a GL context group is destroyed, all multi-group shared
resources associated with the group should be cleaned up.
Otherwise we could get a double deletion in the resource's
destructor, because it still retained a pointer to the
deleted group.
The missing cleanup resulted in a crash when the global
static qt_gl_functions_resource was destroyed, first seen
in the tst_examples autotest in qtdeclarative. It possibly
didn't manifest before because it's event loop-dependent
(the contexts are deleted via deleteLater()).
