* generator/*.cs: add DefaultValue prop for obtaining a
sane value when we need to return a value but something bad has
happened such that we can't get a real value. Needed for iface
signal marshaling, among other places we're partially working
around it now.
svn path=/trunk/gtk-sharp/; revision=86157
* generator/Makefile.am : add new file.
* generator/SimpleBase.cs : new class for non-generated type mappers.
* generator/*Gen.cs : first refactoring of "Simple" generatable types.
Derive them all from SimpleBase. More to come.
svn path=/trunk/gtk-sharp/; revision=38097
* generator/*Gen.cs : add ToNativeReturnType to deal with
the g_free string nonsense in the virtual method case.
