2189e0f2fc rhi: Make the new direct buffer update available for non-uniform buffers
The original restriction to UniformBuffer was due to the GL backend
where there is no GL buffer object for QRhiBuffers with usage
UniformBuffer. However, we can still implement this for cases when
there is a true GL buffer object underneath. With other backends it
should all work as-is already.

This becomes useful when one has buffers with usage Vertex that need
full updates every frame. (f.ex. instance data)

Unfortunately this involves renaming the function. But while at it, add
an autotest case as well.

in QPA and elsewhere.

89f7a2759c Deliver Quit event when calling QCoreApplication::quit()
Instead of QCoreApplication::quit() directly calling exit(0), which would
leave QGuiApplication and client code out of the loop, we now send the
Quit event, and let it pass through event delivery, before finally ending
up in QCoreApplication::event(), where we call exit(0).

This has the advantage that QGuiApplication can ensure all windows are
closed before quitting, and if any of those windows ignore the close
event the quit will be aborted. This aligns the behavior of synthetic
quits via QCoreApplication::quit() with spontaneous quits from the
platform via QGuiApplicationPrivate::processApplicationTermination.

Clients who wish to exit the application without any event delivery or
potential user interaction can call the lower level exit() function
directly.

[ChangeLog][QtGui] Application termination via qApp->quit() will now
deliver Quit events to the application, which in turn will result in
application windows being closed as part of the application quit,
with an option to cancel the application quit by ignoring the close
event. Clients who explicitly want to exit the application without
any user interaction should call QCoreApplication::exit() explicitly.

0f39cfae93 Change QWidget::enterEvent signature to take a QEnterEvent
This is a source incompatible change for widget implementors.
Leaving the old enterEvent as a virtual overload is problematic due to
shadowing. Best to make a clean cut, widget reimplementors will get a compile
time warning if they mark their override as such, or if they try to call the
parent class implementation.

Addresses ### Qt 6 comment.

[ChangeLog][QtWidgets][QWidget] The virtual enterEvent handler now receives
a QEnterEvent, which contains information about mouse position and button
states, rather than a plain QEvent.

4e400369c0 Refactor pointer event hierarchy
Some goals that have hopefully been achieved are:
- make QPointerEvent and QEventPoint resemble their Qt Quick
  counterparts to such an extent that we can remove those wrappers
  and go back to delivering the original events in Qt Quick
- make QEventPoint much smaller than QTouchEvent::TouchPoint, with no pimpl
- remove most public setters
- reduce the usage of complex constructors that take many arguments
- don't repeat ourselves: move accessors and storage upwards
  rather than having redundant ones in subclasses
- standardize the set of accessors in QPointerEvent
- maintain source compatibility as much as possible: do not require
  modifying event-handling code in any QWidget subclass

To avoid public setters we now introduce a few QMutable* subclasses.
This is a bit like the Builder pattern except that it doesn't involve
constructing a separate disposable object: the main event type can be
cast to the mutable type at any time to enable modifications, iff the
code is linked with gui-private. Therefore event classes can have
less-"complete" constructors, because internal Qt code can use setters
the same way it could use the ones in QTouchEvent before; and the event
classes don't need many friends. Even some read-accessors can be kept
private unless we are sure we want to expose them.

6ff79478a4 Introduce platform API abstraction for QOpenGLContext
The API is available by including qopenglcontext.h as usual,
but scoped in the QPlatformInterface namespace. The namespace
exposes platform specific type-safe interfaces that provide:

 a) Factory functions for adopting native contexts, e.g.

    QCocoaGLContext::fromNative(nsContext, shareContext);

 b) Access to underlying native handles, e.g.

    openGLContext->platformInterface<QCocoaGLContext>->nativeContext()

 c) Platform specific functionality, e.g.

    static QWGLContext::openGLModuleHandle()

    openGLContext->platformInterface<QEGLContext>->doSomething();

The platform interfaces live close to the classes they extend,
removing the need for complex indirection and plumbing, and
avoids kitchen-sink modules and APIs such as the extras modules,
QPlatformFunctions, or QPlatformNativeInterface.

In the case of QOpenGLContext these platform APIs are backed
by the platform plugin, so dynamic_cast is used to ensure the
platform plugin supports the requested interface, but this is
and implementation detail. The interface APIs are agnostic
to where the implementation lives, while still being available
to the user as part of the APIs they extend/augment.

The documentation will be restored when the dust settles.
