Attempt to complete the userspace integration of POSIX.1e extended ACLs.
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.

Fixed some style bugs in revs 1.1 and 1.4.

Fix warnings inspired by lint, a commercial lint and WARNS=4.

Modernization effort for bin/c*:

o __P has been reoved
o Old-style K&R declarations have been converted to new C89 style
o register has been removed
o prototype for main() has been removed (gcc3 makes it an error)
o int main(int argc, char *argv[]) is the preferred main definition.
o Attempt to not break style(9) conformance for declarations more than
they already are.

Approved by: arch@, new style(9)

Removed the broken code which claimed to lose the set[ug]id bits in
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.

Migrate from using MAXPATHLEN to MAX_PATH. Use strlcpy to copy the
strings.

$Id$ -> $FreeBSD$

Add a verbose mode to show what files are being copied.

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
