QSignalBlocker: (new) RAII class for QObject::blockSignals()
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.
