    bug 2443: bin/cp: sync with FreeBSD (bug fixes + new options)
    
    * Fix FTS_NOCHDIR behavior on empty directory.
    * Add -a option (archive mode, equivalent to -RpP)
    * Add -l option (create hard links instead of copying)
    * Add -x option (FS mount points are not traversed)
    * Preserve file flags on symlinks on cp -Rp
    * Don't copy socket anyway after "xxx is a socket (not copied)"
    * Avoid division-by-zero situations
    * make -r synonym for -R but maintain -r behavior with -L
