Copy head to stable/9 as part of 9.0-RELEASE release cycle.

The previous commit message was wrong. It should have read:

"Fix bootparamd on 64 bit platforms - at least amd64 was broken due to the
code believing long == 32 bits and using it to store/compare IPv4 addresses."

Note the "== 32 bits" - the previous commit message stated 64 bits, which is
plain wrong.

Perform a major cleanup of the usr.sbin Makefiles.
These are not perfectly in agreement with each other style-wise, but they
are orders of orders of magnitude more consistent style-wise than before.

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.
