Introduce ACL man pages en masse for library calls, and general introduction.
Also, fix acl_valid.c non-portable calls to include _np in their names,
making them standard-happy as well as consistent with acl.h
- clean up unneeded AFS ID type
- Add Coda, NTFS, NWFS ACL types
- Add acl_dup() prototype
- Remove acl_calc_mask, which belongs in the editing library
- Introduce posix1e.3, a man page introducing POSIX.1e library calls
(more man pages to follow)
