Fix VERBOSE reporting on results when removing _PATH_LOCALTIME for UTC option.

PR: bin/164976
Submitted by: dteske

Grammar: tzsetup now has more than one option.

It's not an error if unlink(2) fails because the pathname doesn't exist.

Clean up reinstall option and remove duplicate code

- Move the reinstall logic to be before menus are initialised
(menus are not needed when reinstalling a zonefile).

- Remove unnecessary re-initialization of path_db.

- Update variable name and error message because we now use the
zone name relative to /usr/share/zoneinfo, not the full path.

Use a reasonable-sized buffer when formatting error messages about

mdoc(7) police:

Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text.
Not only this slows down the mdoc(7) processing significantly, but it also
has an undesired (in this case) effect of disabling hyphenation within the
entire enclosed block.

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.

Remove -Wall. It breaks compiling with non-gcc compilers.

Revert $FreeBSD$ to $Id$

Ask about local or UTC here, like we used to.

At the end it was much simpler than I thought. 26 * 26 = 676 and not 576.
South Africa and a few other countries exists again. This fix pr 2595.
This should go into 2.2.

Make some of the less necessary user feedback #ifdef VERBOSE.

We could also make this stuff only come out when getpid() != 1
and thus avoid the install case (where it really is just too verbose,
and people have complained), but this seems less messy and no one
complained when tzsetup didn't print the final "things went fine!"
messages (which sort of contravene the UNIX spirit of only yelling
when you need to anyway).

Sort cross references.

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 two uninitialized and unused variables that used to cause a
segfault before.

Completely re-vamped `tzsetup':

- It no longer attempts to fiddle wall-vs-UTC-in-RTC. The results
were just confusing most of the time.

- The program no longer contains a pre-compiled list of timezones
(compiled by groveling through the tzdata source files for comments
starting with `ZONE-DESCR'). Now it uses the new `zone.tab' file
supplied with current versions of the timezone data files, to determine
the list at run time. (It also requires the ISO 3166 table I
committed some months ago.)

AS A RESULT, this program will NOT work until the new timezone data files
are committed (should happen sometime soon).

Removed unused `-I.'s from CFLAGS.

"." means the object directory, so it is just confusing to use it
when nothing is included from the object directory unless the object
directory is also the source directory. It is confusing for "."
not to mean the source directory anyway, so used `-I.'s should be
replaced by `-I${.OBJDIR}'.

sync copyright with /usr/share/examples/etc/bsd-style-copyright

add pathnames.h, -Wall cleanup

Only print the selected timezone in verification rather than the bogus time.

Copy /etc/localtime, unless it's already a symlink.

Another round of fixes:

. Replace my NIH-suffering code to detect the number of lines on
the terminal by the curses variable LINES.

. Fix the selection code for countries with more than one screenful
of locations. The very few people living in America/US/Pacific
now won't be charged for Indiana any longer... :)

. Removed the gross code that copied over the timezone file to
/etc/localtime, and create a symlink now instead.

All this was horribly broken. The menues were overflowing, the `diff'
calculation wrong, bogus `reboot now!' hints given, and the displayed
month off by one.

Fix all of this.
