More -Wmissing-variable-declarations fixes.

In addition to adding missing `static' keywords:
- bin/dd: Pull in `extern.h' to guarantee consistency with source file.
- libexec/rpc.rusersd: Move shared globals into an extern.h.
- libexec/talkd: Move `debug' and `hostname' into extern.h.
- usr.bin/cksum: Put counters in extern.h, as they are used by ckdist/mtree.
- usr.bin/m4: Move `end_result' into extern.h.
- usr.sbin/services_mkdb: Move shared globals into an extern.h.

Port all apps in libexec/ from libulog to utmpx.

Make rpc.ruserd work with utmpx/libulog.

Because strings are now null-terminated, I've decided to just use an
array of utmpx structures, instead of the separated strings. This means
we just copy the entire utmpx structure and point to the strings within
the structures directly.

Perform cleanups to rpc.rusersd:

- Perform whitespace fixes. Use tabs instead of 8 spaces.
- Make it build at WARNS=6.

Include stdlib.h to get exit()'s prototype.

Spell void * as void * rather than caddr_t. This is complicated by the
fact that caddr_t is often misspelled as char *.

o __P removal
o use new style prototypes and function definitions
o signal handlers need an argument. Mark it unused.

$Id$ -> $FreeBSD$

Make these programs compile and work correctly now that /usr/include/rpcsvc
has been ANSI-fied.

Pointed out by: bde

Remove unused #includes and make it compile again with -DDEBUG. Use syslog()
instead of errx() when being a daemon.

Use err(3). -Wall cleaning. cosmetics in man page.

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.

Remove trailing whitespace.

Make two variables static so that the compiler warnings are
vanishing. As far as i know rpc.rusersd is single_threaded, so
this shouldn't be a problem.

__386BSD__ -> __FreeBSD__

I know that many of these entries are bogus and need to be revisited,
but let's get the tree working again for now and then do a pass through
looking at all the __FreeBSD__ entries, shall we?

This commit was generated by cvs2svn to compensate for changes in r2337,
which included commits to RCS files with non-trunk default branches.
