Fix unused parameter warnings and handle them as build error

• Component: New Bugs
• Status: RESOLVED WONTFIX

[Csaba Osztrogonác]

I noticed zillion patches fix newly introduced unused parameter
warnings on GTK and EFL. Now they are handled as warnings, not error.
Mac port handles unused parameters as build error, except in WebKit,
WebKit2 and WebInspectorUI. ( WebInspectorUI is warning free now, but 
there are zillion warnings in WebKit and Webkit2. )

I think we should stop this dog-cat game, introducing new 
warnings, fixing them, new warnings, fixing them ...

I propose fixing all of them now and then handle them as errors
to avoid introducing these warnings again and again.

note: I haven't fixed WebKit1 and don't want to do it, because it 
is used by only Apple, warnings in it don't affect GTK and EFL.

It would be too big change, close as wontfix.
