* codegen/defs-parse.pl (get_sighandler): gen the helper class. arg
passing and return value handling need beefing up still.
* glib/SignalArgs.cs : New arg passing/ return value handling class.
* glib/SignalCallback.cs (dtor): kill, this will be gen'd in the
subclasses. (ctor): prune down to two params.
svn path=/trunk/gtk-sharp/; revision=1438
* codegen/defs-parse.pl : mkdir the glib/generated dir.
(gen_signal): Call new get_sighandler sub. Doesn't use the returned
value yet. s/event/ev3nt on arg names.
(get_sighandler): new sub to lookup or gen a signal helper/delegate.
Only generates the delegate so far.
* codegen/hardcoded.defs : Added a stub for Gdk.Event.
* gdk/Event.cs : Killed, now a generated struct.
* gdk/SimpleEvent.cs (SimpleEventCallback): Use Marshal.PtrToStructure
to create the Event, not a ctor(IntPtr).
* glib/SignalCallback.cs : New abstract base class for signal helpers.
