Stop using MAXBSIZE to eliminate sys/param.h including (which injects a
ton of namespace intrusion). Create local sizes, and refactor some code
along the way.
ok millert

For open/openat, if the flags parameter does not contain O_CREAT, the
3rd (variadic) mode_t parameter is irrelevant. Many developers in the past
have passed mode_t (0, 044, 0644, or such), which might lead future people
to copy this broken idiom, and perhaps even believe this parameter has some
meaning or implication or application. Delete them all.
This comes out of a conversation where tb@ noticed that a strange (but
intentional) pledge behaviour is to always knock-out high-bits from
mode_t on a number of system calls as a safety factor, and his bewilderment
that this appeared to be happening against valid modes (at least visually),
but no sorry, they are all irrelevant junk. They could all be 0xdeafbeef.
ok millert

When system calls indicate an error they return -1, not some arbitrary
value < 0. errno is only updated in this case. Change all (most?)
callers of syscalls to follow this better, and let's see if this strictness
helps us in the future.

Implement cp -a ("archive" mode)

Not standard, but supported at least by GNU cp, IllumOS, NetBSD,
FreeBSD, DragonflyBSD. No need to be gratuitously different. This
should also allow us to drop patches in ~10 ports.

if we ever activate that, this may need fixing

set set*id bits only if the target did not exist and -p was not used;
from netbsd, prompted by Jesus Sanchez. ok miller@

rcsid[] and sccsid[] and copyright[] are essentially unmaintained (and
unmaintainable). these days, people use source. these id's do not provide
any benefit, and do hurt the small install media
(the 33,000 line diff is essentially mechanical)
ok with the idea millert, ok dms

warn should return an error message for chmod, not for chown

ok millert@

"source" and "target" can be either files or directories;
cp(1) and ln(1) must have a synopsis consistent with mkdir(1),
mv(1), rmdir(1) and others

ok jmc@, millert@, otto@

when copying regular files, look for blocks of zeroes. when we see them,
just lseek ahead to create a sparse file. saves disk and time.
note this behavior in the man page.
ok? deraadt millert

sort options + sync usage();

madvise mmapped memory (not used code)

Remove some double semicolons (hmm, do two semis equal a maxi?).
I've skipped the GNU stuff for now. From Patrick Latifi.

spacing

Remove the advertising clause in the UCB license which Berkeley
rescinded 22 July 1999. Proofed by myself and Theo.

Undo a misguided attempt to fix speling errors from long ago. UCB
copyrights say "acknowledgement", not "acknowledgment". You cannot
just go changing the text of a license willy-nilly.

explicit braces to avoid ambiguous else

Explicit mapping type to mmap. (not used yet)

"cp -f" should unlink the destination before copying. Similar to
a patch from FreeBSD (but this is simpler). Closes PR #821

for -p preserve sticky bit

use MAP_FAILED

readlink(path, buf, sizeof buf-1). Never forget that -1.

spelling

i am bored enough to fix terminal space/tab uglies

improve error message (yes I know mmap(2) isn't used yet.)

bad usage line; oster@cs.usask.ca

Patch from BSDI (via Keith Bostic, via NetBSD):

Better fix for -p and links.

Only update owner (via lchown) when dealing with symbolic links.
Fixes core dump problem with ``-p'' and symbolic links. Noted by
Carsten Hammer <chammer@post.uni-bielefeld.de>.

support for lchown(2) if "-p" is used

update rcsid
