"""Exit codes a test reports to runtests.py (autotools test convention).

Shared by runtests.py (the harness, which reads these from each test) and
pppfns.py (the helpers, which exit with them) so the 0/1/2/77/78 values are
named in exactly one place.  This module has no import-time side effects, so
runtests.py can import it without pulling in pppfns's environment checks.
