Fold mkpasswd applet into cryptpw.
mkpasswd is in Debian, OTOH cryptpw was added to busybox earlier.
Trying to make both camps happy by making those two applets just aliases.
They are command-line compatible. We can decide whether we want to drop one

Example: rather than quit when an initial lease isn't found,
you could use "--background" so that udhcpc keeps running and
continually attempts to get an ip.  That way, when you plug in
