If adding a QLineEdit to a QGraphicsScene as a QGraphicsProxyWidget, the popup
completion of that QLineEdit is drawn in the wrong location. When the completer
getting the rect of screen, it gets the rect of the QGraphicsScene where
QLineEdit is located rather than the rect of the screen, resulting in an error
in the following calculation.
Note that as long as the completer popup is a toplevel widget not parented
to the target widget, it will not be automatically embedded into the graphics
view via QGraphicsProxyWidget. So with multiple views for a scene, or in views
that use transformations, the geometry will still be off.

While 'pure' in GCC is weaker than Stepanov's Regular Procedure from
Elements of Programming (equal result for equal inputs), it does not
allow accesses to volatile memory:
> functions declared with the pure attribute can safely read any
> non-volatile objects
The globalSeed() function reads from an atomic variable that can be
changed at any time from another thread.
Atomics, while not volatile objects in the sense of the keyword, must
fall under the pure attribute doc's exclusion criterion:
The difference between a volatile and an atomic access, while
important for the implementation of the function, is indistinguishable
to the caller of the function: both volatile and atomic objects can
change value without the current thread of execution changing them,
with no way for the caller of the function to distinguish which one
occurred.
Therefore, globalSeed() should not be pure.
5.15 is not affected, as qGlobalQHashSeed() is not marked as pure.

The registry is designed to be thread-safe, as is openUrl(), and
handlers are required to be thread-safe, too: "the handler will
always be called from within the same thread that calls
QDesktopServices::openUrl()".
The handlerDestroyed() slot was invoked using AutoConnection
semantics, which, if the registry and the handler happen to not be on
the same thread, is QueuedConnection, which means there's a window in
which the handler is destroyed, but it's still listed in the registry,
and a call to openUrl() may make a call to the (deleted) handler.
Worse, if a handler is deleted and new one registered they may end up
on the same address (ABA, or rather, AA problem), and then the delayed
call to handlerDestroyed() may remove the entries to the new handler,
as well as those to the old.
Fix by using Qt::DirectConnection. This fixes the ABA problem, but
doesn't completely fix the partially-destroyed problem, since
QObject::destroyed() is simply too late. We need to require explicit
unsetUrlHandler() calls, which should happen before destruction of the
handler object starts.

The handlerDestroyed() function is connected to the handler QObject's
destroyed() signal and removes all entries from the registry for which
the destroyed object was listed as the handler.
While handlerDestroyed() is always executed in the context of the
thread owning QOpenUrlHandlerRegistry-as-a-QObject, the documentation
explicitly states that "the handler will always be called from within
the same thread that calls QDesktopServices::openUrl()", implying that
calling openUrl() from a non-GUI thread is supported. The presence of
the mutex also indicates that this should work.
But then the unprotected access to the handlers variable in
handlerDestroyed() is a data race, because nothing prevents a handler
object from being destroyed concurrent to an openUrl() call.
Fix by locking the mutex.
