with the same name exists, delete that directory first, before performing
the copy. This ensures that mv(1) across devices follows the semantics
of rename(2), as required by POSIX.
This change could introduce the potential of data loss, even if the
copy fails, violating the atomicity properties of rename(2). This is
(mostly) mitigated by first renaming the destination and obliterating
it only after a succesfull copy.
The above logic also led to the introduction of code that will cleanup
the results of a partial copy, if a cross-device copy fails.

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.

instead.
Some of these (mv, find, apply, xargs) might benefit greatly from
being rewritten to use vfork() properly.
