Remove a useless cast.

Spotted out by: stefanf

Char is unsigned on arm, so is not suitable to store the return value of
getopt(). Use an int instead.

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

- Cast isdigit's argument to unsigned char.
- Remove the now unused variable i.

$Id$ -> $FreeBSD$

#include <arpa/inet.h> for inet_* definitions.

Use err(3). Add usage and prototypes. Remove Xref: Diskless(8) does not
exist. Use An/Aq macros for Author.

compare return value from getopt against -1 rather than EOF, per the final
posix standard on the topic.

Revert $FreeBSD$ to $Id$

Make the long-awaited change from $Id$ to $FreeBSD$

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.

main.c:
- use daemon() to daemonify ourselves
- the 'Usage' printf() was missing an argument
- remove declaration of rindex and #include <string.h> instead

bootparam.c:
- get rid of local declarations of YP functions and include headers
from /usr/include/rpcsvc instead.

Remove trailing whitespace.

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.
