GtkSharp/glib/Variant.cs
Mike Kestner 8459ac5560 Initial support for GVariant
* 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.
