Subject: Add the following ACL editing functions:   acl_add_perm,
 acl_clear_perms, acl_copy_entry, acl_create_entry,   acl_delete_perm,
 acl_get_permset, acl_get_qualifier, acl_get_tag_type,   acl_set_permset,
 acl_set_qualifier, acl_set_tag_type

This brings us within 4 functions of a full ACL editing library.
