Python3 complains if a dict key is changed during the
iteration.

Use list() to create a copy of it.

Traceback (most recent call last):
  File "./ovsdb/ovsdb-idlc.in", line 1581, in <module>
    func(*args[1:])
  File "./ovsdb/ovsdb-idlc.in", line 185, in printCIDLHeader
    replace_cplusplus_keyword(schema)
  File "./ovsdb/ovsdb-idlc.in", line 179, in replace_cplusplus_keyword
    for columnName in table.columns:
RuntimeError: dictionary keys changed during iteration
