At a Xen Summit design session for the golang bindings (see [1]), we
agreed that it would be beneficial to expand the libxl IDL with function
support. In addition to benefiting libxl itself, this would allow other
language bindings to easily generate function wrappers.

These RFC patches outline a potential strategy for accomplishing this
goal. The first patch adds the Function and CtxFunction classes to
libxl/idl.py, introducing the idea of functions to the IDL. The second
patch adds a DeviceFunction class and adds some sample definitions to
libxl/libxl_types.idl for example purposes.
