Log Message:
Update to OpenPAM Figwort (20050616):
- BUGFIX: Correct several small signedness and initialization bugs
  discovered during review by the NetBSD team.

- BUGFIX: Modify gendoc.pl to sort cross-references in dictionary
  order within each section.

- ENHANCE: if a policy specifies a relative module path,
  prepend the
  module directory so we never call dlopen(3) with a relative
  path.

- ENHANCE: add a pam.conf(5) manual page.
