[Xen-devel] [PATCH]: xl: cleanups for IDL code

[Gianni Tedesco <gianni.tedesco@xxxxxxxxxx>]

Introduce a libxltypes.Number class to be inherited by all numeric types
regardless of whether they are fixed width or int/long. Also maintain a
rawname attribute for types so that we can find the name without the
namespace prefix. This is in preparation for using the IDL code to
auto-generate (a lot of) boilerplate for language bindings.
