* generator/GenBase.cs: new method AppendCustom, moved from ObjectGen. * generator/BoxedGen.cs, ObjectGen.cs, StructGen.cs: Call AppendCustom in Generate (); * generator/Method.cs, Parameters.cs: Add support for "out" parameters. Additionally, output an accessor instead of a regular method if it is an accessor-style function (ie GetStartIter). * generator/Property.cs: Add additional cast to Boxed, if necessary. * glue/textiter.c: New constructor for GtkTextIter. * glue/Makefile.am: Add textiter.c, build with Gtk+ cflags. * configure.in: Check for Gtk+ cflags. * parser/Metadata.pm, Gtk.metadata: Added. * parser/gapi2xml.pl: Call Metadata::fixup on the document. Also work around gtk's screwy boxed type name registration (GtkFoo -> GtkTypeFoo). * gtk/TextIter.custom: Added. svn path=/trunk/gtk-sharp/; revision=5205
