7dc88b6890 Add support for OpenGL 3.2+ core profile contexts in QPainter
This change allows painting via QPainter onto a QOpenGLWindow, QOpenGLWidget
or QOpenGLFramebufferObject when an core profile context is in use. This is
important on macOS in particular, where compatibility profiles are not
available, and so the only way to use modern OpenGL is via a core profile
context.

Added core profile compatible shaders with moder GLSL keywords.

The paint engine binds a VAO and two VBOs from now on, whenever VAOs are
supported. Note that this changes behavior also for OpenGL 2.x context that
have VAO support via extensions.

The Lancelot test suite gains support for core profile contexts. This can
be triggered via -coreglbuffer in place of -glbuffer when manually inspecting
via 'lance', while tst_lancelot will automatically run core context-based tests
whenever supported.

cd1d114140 Unset qgl_current_fbo when the default FBO is bound
Previously when a new QOpenGLFramebufferObject was bound, the
QOpenGLContextPrivate::qgl_current_fbo member was also updated to point
to this new object.
But if a user called QOpenGLFramebufferObject::bindDefault(),
qgl_current_fbo was not unset, meaning that if the FBO object would be
deleted at some point, qgl_current_fbo would be a dangling pointer.

This patch makes sure to clear the value of qgl_current_fbo when
bindDefault() is called. It is cleared, and not set to point to another
object because the default platform OpenGL FBO is not backed by a
QOpenGLFramebufferObject.

5adbb9cc57 Support Alpha8 and Grayscale8 natively in the OpenGL paint engine
Adds special shaders for the Alpha8 and Grayscale8 formats so that
they do not need to rely on the support of GL_ALPHA and GL_LUMINANCE
that has been removed from core in recent OpenGL versions.

bb760d9514 Add support for glMapBufferRange in the wrappers and resolvers
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().

22e4391413 Add default format to QSurfaceFormat
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.
