Introduce six new options from NetBSD:

 * -M <metalog>   Log metadata in mtree format.
 * -D <destdir>   Log paths relative to <destdir>.
 * -h <hash>      Log digest of type <hash>.
 * -T <tags>      Specify which mtree tags to log.
 * -l <linkflag>  Create hard or symbolic links (allows logging).
 * -U             Install without root privileges (owner, group, mode,
                  and flags can be logged via -M

NOTE: In the interest of compatibility with NetBSD and because it is the
obvious letter, the nearly useless -M option (disable mmap) has been
repurposed.

+	The install(1) option -M has changed meaning and now takes an
