[Xen-devel] [PATCH v3 04/22] golang/xenlight: define KeyValueList as empty struct

From: Nick Rosbrook <rosbrookn@xxxxxxxxxxxx>

Define KeyValueList as empty struct as there is currently no reason for
this type to be available in the Go package.

Implement fromC and toC functions as no-ops.

Signed-off-by: Nick Rosbrook <rosbrookn@xxxxxxxxxxxx>
Reviewed-by: George Dunlap <george.dunlap@xxxxxxxxxx>
Changes in v2:
- Re-define KeyValueList as empty struct, as it was decided this type
  probably shouldn't be exposed in the Go package.
