Implements a pam module for automatically loading zfs encryption keys
for home datasets. The pam module:
- loads a zfs key and mounts the dataset when a session opens.
- unmounts the dataset and unloads the key when the session closes.
- when the user is logged on and changes the password, the module
changes the encryption key.
