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

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

Setting .nofinger will not hide you from root.

If stat() on the terminal specified in utmp fails due to ENOENT, don't
print a warning, and set the idletime variable for the entry to -1;
then pick up the -1 later in sprint() and lprint() and ignore those
idle times by printing just whitespace. When third party applications,
such as kdm, insert utmp entries, they sometimes use strings like ":0",
which can't be stat()'d and currently result in warnings that are
not helpful to the user.

ANSIify function definitions.
Add some constness to avoid some warnings.
Remove use register keyword.
Deal with missing/unneeded extern/prototypes.
Some minor type changes/casts to avoid warnings.

Clean up malloc(3)'s argument. Remove casts which do nothing when we're
using sizeof() anyway. Use slightly more consistent (per-file) error
reporting for malloc(3) returning NULL. If "malloc failed" was being printed,
don't use err(3). If a NULL format is being used, use err(3). In one case
errx(3) was being used with strerror(3), so just use err(3).

remove __P

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().

Replace the condemned access(2) by stat(2),
as per the discussion in -audit.

Don't use ".nofinger" as a string constant from within the code
since there is the ``pathnames.h'' file; use _PATH_NOFINGER instead.

MAXPATHLEN is enough.

Also, snprinf is guaranteed by the new ansi standard to NUL terminate the
string, so we don't need to do that ourselves.

Spelling
Remove unused #includes

Check strdup() return values

If the utmp login time is greater than the tty atime, use it to calculate
the idle time instead of the atime.

This makes entries for people that have logged in but done nothing
else show up correctly.

Fix possible buffer overflow with finger and fingerd.

This patch is actually a combination of those two patches.

Install Luke's enhancements for finger.

By default, behave like the old ugly 4.4bsd finger and print office
information instead of remote login information.

It's an easy one line fix to make it behave like most other vendor's
fingers if we decide to change the default.
