Assume an unrelated class that declares an enum and uses Q_ENUMS. Consider
then a class that uses UnrelatedClass::Enum as a Q_PROPERTY. We used to
include UnrelatedClass in the primary class's related meta objects, in order
to support use-cases like
obj->setProperty("enumProperty", "ValueOfEnumAsString");
If however moc happens to see Q_DECLARE_METATYPE(UnrelatedClass::Enum), then it
would exclude it from the related meta objects, which would silently break the
string based enum value conversion. This was meant as an optimization, but it
isn't apparent to the developer why sometimes the string conversion would
work and sometimes not (depending on whether somebody declares that macro).
This also becomes visible in QML, which relies on the same embedded type
information for enum assignments.
This patch removes that check in moc's code generator and cleans up the code a
little. However always including the prefix of Q_PROPERTY(SomePrefix::Enum ...)
is not correct either, because it may be that SomePrefix is a namespace, which
would cause compilation issues. Therefore we limit the inclusion of related
meta objects only to Q_OBJECT decorated classes the moc has seen, and for these
we save the fully qualified name in the related meta objects array (for QTBUG-2151).
While this patch makes the previous workaround for namespace issues by using a
Q_DECLARE_METATYPE not workable anymore, by saving the fully qualified name we
are making a hopefully sufficient effort to not require a workaround in the
first place. There's always the new workaround of fully qualifying the type in
Q_PROPERTY.
One side-effect of this change is that in the autoPropertyMetaTypeRegistration
test of tst_moc, the CustomQObject for Q_PROPERTY(CustomQObject::Number
enumValue ...) is now a related meta object, and therefore when querying for
the type of this property via QMetaProperty::userType(), we are now aware of
this being an enum and try to resolve CustomQObject::Number via
QMetaType::type(qualfiedName). As there is no guarantee for this to succeed, we
must now also do what is done in the non-enum code path in ::userType(), which
is to call the moc generated type registration function.

Instead of enforcing the check, we'll simply trust developers to do the

check is mostly superfluous.

QHash::key() is O(n) and we're calling it n times. That can make repeated

Fortunately this is easy to fix, as the value in the hash map is also the
index, so we can simply iterate over the hash once. With the exception of
the class name, which we have to treat specially to ensure that it is always
the first entry in the string table.

As the last line in the QObject destructor, we call setParentHelper(0) to

re-introduce the check there, but I think it's cleaner to not bother calling
the callback on a dead object in the first place.

Qml has a bunch of hooks in QObject, that are callbacks as function pointers
when things happen in QObject. QtDeclarative (Qml1) only needs one callback,
for object destruction. In preparation for allowing both run-times to co-exist,
this patch forks the callback, keeping the "default" variant for QtQml and
having a *_qml1 variant for QtDeclarative. QtQml continues to set the callback
variable for the default and QtDeclarative will set the _qml1 variant.
It is however a limitation that a QObject instance can only be exposed to _one_
engine at a time, and it is not possible to make a transfer. Double exposure
will result in crashes.
This patch alone is not sufficient to fix the bug, the
QQmlData/QDeclarativeData structures in Qml1 and Qml2 need to be extended to
allow distinction at run-time.

I don't think I ever worked on a project of non-trivial
size that didn't at some point add a QSignalBlocker.
This commit adds code, tests and documentation. Later
commits will convert naked blockSignals() calls to use
QSignalBlocker.
The implementation is purely inline to avoid the heavy
overhead of cross-dll function calls for this miniscule
task. This should not be a problem because QSignalBlocker
only uses public API and a pattern that we anyway need
to keep working until Qt 6, at least, so even changing
the implementation later will be no problem as the old
implementation lurking in non-recompiled code will be
acceptable, too.
This implementation is an evolution from KDTools'
KDSignalBlocker, with the following changes:
- Implements unblock() and reblock()
- Uses the return value of blockSignals() instead of a
separate signalsBlocked() call.
