Chris D. Faulhaber 4bf60dfaf8 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.
