Joachim Wiberg e88a9b14ff Fix #101: remove built-in inetd from finit 
This patch removes the built-in inetd support from Finit.  We recommend
using an external inetd instead, e.g. xinetd.

If you liked the feature set our inetd provided; filtering per interface
and port redirection, then please let us know or use the code in this
patch (MIT licensed) to recreate it.  We are open to reintroducing it,
but then as a stand-alone daemon like the bundled watchdogd and getty.

So long for now, old friend.
