  Log Message:
  -----------
  Fix a possible memory leak in sxnet_v2i

When a subsequent call to SXNET_add_id_asc fails
e.g. because user is a string larger than 64 char
or the zone is a duplicate zone id,
or the zone is not an integer,
a memory leak may be the result.

  Fix a similar memory leak in SXNET_add_id_INTEGER

Even in the good case there was memory leak here.
Add a simple test case to have at least some test coverage.
