Mainly focus on files that use BSD 3-Clause license.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
Special thanks to Wind River for providing access to "The Duke of
Highlander" tool: an older (2014) run over FreeBSD tree was useful as a
starting point.
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.

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.

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.

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.

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.
