I hope I'm doing this right.

This is an initial version of bootparamd for FreeBSD based on a public
domain rpc.bootparamd implementation by a gentleman named Klas Heggemann.
This program has apparently been around for a while. The README explicitly
lists the code as public domain, so I guess it's safe to use.

This program is needed for booting diskless SunOS and Solaris machines.
rarpd is also required, but that's in the works too.

I have made two changes to this code:

- Implemented NIS lookups. If /etc/bootparams contains a '+' then the
  bootparams map is consulted.

- Allow 0.0.0.0 as a user-specified router address. The SunOS rpc.bootparamd
  returns this value in many cases.
