Make TQConnectionList sharedfeat/dedup-tqobject

This commit fixes crashes caused by modifications of TQobject
connections from the slots invoked by its signals. Up to recent time
those were hidden by implementation specificities in
TQObject::activate_signal(), so they would appear only under quite
peculiar circumstances, but after attempts to de-duplicate the code they
surfaced up.

Besides that the patch de-duplicates some code in
TQObject::disconnectInternal().
