[Development] Disconnect Signal 0

[David Narvaez]

Hi all,

I was taking a look at bug 29498[0] and the explanation is pretty
clear on what's happening: disconnect admits char * signal = 0 as a
parameter (which means all signals) but then forwards that parameter
to other calls that apparently do not commit to support 0 as a
possible value.

I can take care of this bug but the question is how do we prefer to
fix it: should we multiplex at QObject::disconnect level or start
looking around to support signal = 0 in all other places?
