Renumber cluase 4 to 3, per what everybody else did when BSD granted
them permission to remove clause 3. My insistance on keeping the same
numbering for legal reasons is too pedantic, so give up on that point.

This is also implemented in at least GNU coreutils cp.
While here also improve the '-l' handling to not open(2) the source file as
it does not actually need the descriptor.

In an attempt to improve performance, cp reordered directories first
(although the comment says directories last). This is not effective with new
UFS layout policies.
The sorting reorders multiple arguments passed to cp, which may be
undesirable.
Additionally, the comparison function does not induce a total order. Per
POSIX, this causes undefined behaviour in qsort().
NetBSD removed the sorting in 2009.
On filesystems that return directory entries in hash/btree order, sorting by
d_fileno before statting improves performance on large directories. However,
this can only be implemented in fts(3).

This includes adding support for ACLs into cp(1) and mv(1) userspace
utilities.
For mv(1), if _PC_ACL_EXTENDED is in effect for the source AND destination
operands, the destination file's ACLs shall reflect the source.
For cp(1), if _PC_ACL_EXTENDED is in effect for both source and destination
operands, and -p has been specified, the ACLs from the source shall be
preserved on the destination.

hack, thereby allowing future extensions to the structure (e.g., for extended
attributes) without rebreaking the ABI. FTSENT now contains a pointer to the
parent stream, which fts_compar() can then take advantage of, avoiding the
undefined behavior previously warned about. As a consequence of this change,
the prototype of the comparison function passed to fts_open() has changed
to reflect the required amount of constness for its use. All callers in the
tree are updated to use the correct prototype.
Comparison functions can now make use of the new parent pointer to access
the new stream-specific private data pointer, which is intended to assist
creation of reentrant library routines which use fts(3) internally.

the !(pflag && setfile()) case for regular files unless the copy is
owned by the same user and group. These bits have already been lost
(or never gained) in the correct way. The code didn't actually lose
the bits; it depended on them being lost already (apparently in all
cases) and attempted to gain them as necessary, but it often gained
them (and sometimes collateral bits) when wrong:
- pflag && setfile() == 0 case (i.e., for a successful cp -p):
setfile() copies all the attributes as correctly as possible (as
specified by POSIX), and we sometimes messed up the up the mode by
setting it again. Also, if the file is immutable, then setting the
mode again gave spurious errors (PR 20646).
- !pflag case. If the target is created, POSIX requires it to not
have the set[ug]id bits, but we sometimes copied them from the source.
If the target already exists, POSIX requires its mode to be unchanged,
but we sometimes copied the whole mode from the source.
