This commit does not belong to any branch on this repository, and may belong to a fork outside of the repository.
Factor out some common functions used by multiple test programs. Use a common argument format for importing names (p:princname, h:hostbasedname, or u:username) and adjust the Python tests to match it. Use more consistent conventions in test programs and fix some coding style issues. Normalize how the test programs are built.
