VISA VPP-4.3 constants (VPP-4.3.2 spec, section 3).
Makes all "completion and error codes", "attribute values", "event type
values", and "values and ranges" defined in the VISA specification VPP-4.3.2,
section 3, available as variable values.
The module exports the values under the original, all-uppercase names.
