* generator/CallbackGen.cs: Generate wrappers to map
from managed delegates to native ones.
* generator/Ctor.cs: Call parms.Initialize for the static case.
* generator/Parameters.cs: Add "CType" property. Append []
to CSType if necessary. Add "HideData" property if a container
wishes to hide the user_data (used in callbacks).
(Initialize): Add case for callback.
* generator/SymbolTable.cs: Add size_t.
* glue/program.c: string[] marshalling is no longer broken,
remove hack.
* sources/Gtk.metadata: Disable
GtkColorSelection.SetChangePaletteHook and
GtkTreeView.GetSearchEqualFunc for now, they return delegates and
we don't support native->managed delegate mapping yet.
