use QOpenGLShaderProgram instances on different threads. These instances

Observed infrequently in the QDBus tests, it would deadlock when
destroying QDBusServer at the same time as qDBusNewConnection was being
executed as they were locking the same locks, but in opposite order.
QDBusServer locks d->lock, then QDBusConnectionManager::instance()->mutex.
While qDBusNewConnection locks QDBusConnectionManager::instance()->mutex,
then serverConnection->lock (and serverConnection here
is QDBusServer's d-pointer).
QOrderedMutexLocker cannot be used in this situation because it
operates on QMutex*, which d->lock (QReadWriteLock) is not.
Change the code to lock QDBusConnectionManager's mutex before d->lock
and then unlock the QMutexLocker where it would previously destruct.
If QDBusConnectionManager has already been destroyed then we pass a
nullptr to the QMutexLocker which is fine and will not do anything.

upper limit of the for loop. If the stack does not contain any
redos, then it would be == undoStack.size() and we would assert.
If there were redos, then we would delete the item at undoState
multiple times (actually undoState times).
In addition, when the loop exited, we first removed the dangling
pointers using remove() and then there was a weird resize() to
the new size minus the old undoState.
This would either assert because we tried to resize to a negative
number, or it would arbitrarily remove items from the stack.

this, we add a separate hash of menu IDs to allow mapping between
Java and C++. For easier book-keeping, we add the hashes to the
menu bar and menu classes, so that we can easily recycle old menu
IDs when they are no longer in use.
Note that overriding the tag on the menus by calling setTag() will
not work, since Qt Widgets will later override it again by setting
it back to the menu's pointer.

Also sanitize the initial WebAssembly hack. Both eglfs and wasm lack the concept
of true raster windows. A QWindow with RasterSurface is rendered with OpenGL
no matter what. The two platforms took two different approaches to work around
the rest of the machinery:
- wasm disabled the QOpenGLContext warning for non-OpenGL QWindows,
- eglfs forced the QWindow surfaceType to OpenGLSurface whenever it was
originally set to RasterSurface.
Now, the latter breaks since c4e9eabc30, leaving
all raster window applications failing on eglfs, because flush in the backingstore
is now checking the surface type and disallows OpenGLSurface windows. (just like
how QOpenGLContext disallows RasterSurface windows)
To solve all this correctly, introduce a new platform capability,
OpenGLOnRasterSurface, and remove the special handling in the platform plugins.

missing was a corresponding acquire fence on load, without which there
is no happens-before relationship between the writes performed by the
QMutex ctor and the reads performed by a subsequent mutex.lock(), say,
on the same data.
Fix by adding acquire fences to all loads. That includes the dtor,
since mutexes may have been created in different threads, and never
been imported into this_thread before the dtor is running.
