Remove the advertising clause from UCB copyrighted files in usr.bin. This

Also add $FreeBSD$ to a few files to keep svn happy.

Migrate finger(1) towards utmpx.

It was already ported to use libulog, which makes it simpler now. Be
sure to catch the error returned by setutxdb(). Otherwise it may perform
a lookup on the utx.active database.

Migrate finger(1) away from <utmp.h>.

Unfortunately it also uses lastlog, which means we must resort to local
extensions of the utmpx-interface. Because the user name and TTY name
are now nul-terminated, there is no need to copy around strings as
often.

Revert most part of 200420 as requested, as more review and polish is
needed.

Remove unneeded header includes from usr.bin/ except contributed code.

Tested with: make universe

Remove T/TCP support, and the -T option which was needed to disable it.

Remove spurious semicolons. Outside of functions they are actually errors but
GCC doesn't warn about them without -pedantic.

Style improvements recommended by Bruce as a follow up to some
of the recent WARNS commits. The idea is:

1) FreeBSD id tags should follow vendor tags.
2) Vendor tags should not be compiled (though copyrights probably should).
3) There should be no blank line between including cdefs and __FBSDIF.

WARNS=2 fix, remove 'register' and use __FBSDID().

Include missing header files which define functions for which gcc has
builtins (e.g., exit, strcmp).

Spelling
Remove unused #includes

-Wall cleanup.

Don't assume ai0->ai_canonname will always be filled in. Print the
user-supplied host name if we can't get a canonical name.

Implement IPv6 support. Also restructure the way multi-homed hosts
are treated, regardless of protocol.

Impliment elements of TCP Wrappers's `safe_finger'.
* if run by root (or root process) drop privs
* ensure output size is not infinate (net finger only)

* do not allow finger client to run longer than 3 minutes (net finger only)

Don't assume that hp->h_lenght == 4. Be conservative in its use.
Submitted by: J. Assange a long time ago.

So somebody actually found language in the FINGER RFC which requires
implementations to leave the client side open until the server closes.
While this is totally idiotic, it seems as if some servers actually require
it (e.g., the one at mit.mit.edu). So, we bow to the weight of the bogus
standard and disable the initial close. Hopefully now fetch(1) can serve
the role of T/TCP demonstration application.

Add rcsid, usage(). Silent -Wall. Use warn(3).

Merge from Lite2

Allow the user to disable the use of T/TCP by setting the -T option.
This option becomes useless when all TCP stacks are fixed out there.

Print 8bit chars from the net if current locale allows them

Implement client-side transaction TCP. This has little effect
if the server doesn't support it. (This is intended mostly as
an example.)

Remove trailing whitespace.

Remove extra newline introduced in Net/2
