initial commit
Initial checkin

Initial locker.py with basic AFS support
Initial checkin of working implementation

liblocker, libathdir, athdir, and attach in Python.
Requires new python-hesiod
Add help options

Since -h does not mean "help", we add our own help options
Always import hesiod

Conditional importing and fuse-python's thread support do
not play nice.  Also, a cleaner error when something goes
horribly wrong during lookup.
Add detach(1), quota(1), fsid(1)

Refactor attach and liblocker.
Add docstrings to athdir.py.
Add a notes file
Cleanup notes file
Add LOCLockers
Cleanup debug messages
Cleanup unmapping message
Support attach -e and -m, cleanup legacy attachtab
Add setup.py
