* generator/SymbolTable.cs : add GVariant type mapping. * glib/Variant.cs: initial implementation of an opaque class to expose the GVariant type from glib. We won't make any attempt to combine managed references since there is no "toggle" ref capability. We'll do a one-to-one ref_sink/unref pair on construction/dispose.
