Changes from SLuRP 0.9a -> SLiRP 0.9b (XX/XX/95)

- Changed the name from SLuRP to SLiRP (slurp allready exists)
- Added telnetd to the source tree, which, if compiled, will be used so that
  arbitrary commands can be executed by SLiRP (eg: by default, if you telnet
  to 192.0.2.1, you'll automatically get a shell instead of a login prompt)
- Completely removed the old way of "address encoding" to dynamically
  configure SLiRP, now you telnet to 192.0.2.0 and you get a "command-line"
  interface to configure SLiRP on-the-fly, as well as many other commands.
- Added the ability to execute a program on connection to a certain
  address/port.
- Changed if_input and if_start to be much smarter.  It's quite clever now :)
  No single session can hog the link, and if one interactive session gets
  greedy, it gets "downgraded" to the same priority as bulk data.
- Ported to SunOS, SCO, AIX.
- Way, way too many small changes to list... (I've forgotten them anyway)
