However there is much code out there (e.g. qtdeclarative) which relies
on QUrl::fromLocalFile("fileName.txt") to be treated as relative, so
for now, we still allow this (in Qt 5.6.x). For Qt 5.8, this commit will

We can't forward a VerticalSortHint or HorizontalSortHint hint, because we might
be filtering extra items.
The documentation of QAbstractItemModel::LayoutChangeHint states:
Note that VerticalSortHint and HorizontalSortHint carry the meaning that
items are being moved within the same parent, not moved to a different
parent in the model, and not filtered out or in.
And some of the views rely on this assumption (QQmlDelegateModel for example)
What happens in the test is the following:
- 'model' emit the dataChanged signal when its data is changed.
- 'proxi1' QSortFilterProxyModelPrivate::_q_sourceDataChanged does not forward
the dataChanged signal imediatly, it will instead first re-sort the model and
call layoutAboutToBeChanged / layouChanged with the VerticalSortHint
- 'proxy2' would forward the layoutAboutToBeChanged with the hint, but in
QSortFilterProxyModelPrivate::_q_sourceLayoutChanged, it will redo the mapping
which will cause the changed data to be filtered.
So proxy2 can't forward the VerticalSortHint as it removed rows in the process.

This change adds back a cut off. This is only needed in the

There was a race condition between QObject::disconnect() and
QMetaObject::activate() which can occur if there are multiple
BlockingQueued connections to one signal from different threads and
they connect/disconnect their connections often.
What can happen in this case is:
T1 is in activate() method and T2 is in disconnect() method
T1 T2
locks sender mutex
selects next connection
unlocks sender mutex
locks sender mutex
sets isSlotObject to false
creates QMetaCallEvent derefs connection
posts event
Two things can happen here:
1. Connection can still be valid, but it will have isSlotObject==false
and callFunction will be used instead of slotObj
2. Connection can already be invalid
To fix it mutex unlock should be moved after QMetaCallEvent creation.
Also there is another case, when we don't disconnect but delete the
receiver object. In this case it can already be invalid during
postEvent, so we need to move mutex unlock after postEvent.
