[Xen-devel] [PATCH v3 09/22] golang/xenlight: define EvLink builtin as empty struct

[Nick Rosbrook <rosbrookn@xxxxxxxxx>]

From: Nick Rosbrook <rosbrookn@xxxxxxxxxxxx>

Define EvLink as empty struct as there is currently no reason the internal of
this type should be used in Go.

Implement fromC and toC functions as no-ops.
