Remove warning about system extended attributes that cannot be copied, since
it will always be displayed when an unprivilegied user moves files across
filesystems (mv(1) uses cp -p in that case). After all, there is no warning
that we loose a setuid bit during a move or copy, so this makes sense.

Fixes bin/45259

Make cp -p and mv preverve extended attributes, and complain if they cannot.

Also introduce library functions for copying extended attributes from one
file to another:
- extattr_copy_file, extattr_copy_fd, extattr_copy_link, with FreeBSD style,
where a namespace is to be supplied
- cpxattr, fcpxattr, lcpxattr, with Linux style, where all namespaces
accessible to the caller are copied, and the others are silently ignored.

Fix the "dne" handling and chmod behaviour properly: values of dne
need to be on a stack instead of being a single variable since
directories are processed depth-first. Otherwise dne randomly
depends on the previously processed entry.

This fixes both chmod of non-created directories (they used to be
chmod'd even when not created if their last child element did not
exist in the target subtree) and a "foo exists" bug exposed by my
last commit which removed directory sorting.

all regression tests passed

Remove fts sorting. It was originally put there to copy files
before directories since files (usually) are in the same cylinder
group and subdirectories aren't. However, this mostly changed with
the new ffs dirpref algorithm in 2001.

No sorting has two effects:
1) copy appears to be somewhat faster (e.g. on my laptop cp'ing build
objdir to tmpfs is 7% faster after the change)
2) source file parameters no longer get randomly shuffled due to
fts doing an unstable sort of them. this means that
"cp 1 2 3 4 dest/" will copy the files in that order instead
of e.g. 3 4 1 2.

Remove the \n and tabs from the __COPYRIGHT() strings.

Distinguish "this file failed" from "any file failed", to make cp -v
output behave itself. PR bin/37018 from Dieter Roelants.

(I used a slightly different patch to make sure "any file failed"
didn't get lost in the shuffle, and renamed the variables in the name
of greater clarity.)

Suggested by David Holland on "source-changes-d" mailing list.

Disable mmap path. With the current vnode locking scheme it has
a very annoying property: if the source media is slow (like a slow
network), the target file will be locked for the duration of the
entire max 8MB write and cause processes attempting to e.g. stat()
it to "tstile" (for several minutes in the worst case). Revisit
this if/when vnode locking gets a little smarter.

chs ok (although he would rather see vnode locking improvements,
but that's a slightly larger project)

Add -N to usage.

Touching up the permissions to preserve set-ID bits is appropriate
only in the case where the destination did not previously exist, and

Don't remove the destination file if there is a write error. This is
