wollman@ has OK'd dropping his maintainership of zic(8)

Submitted by: linimon
Approved by: wollman (via linimon)

Set wollman as the MAINTAINER and mention the vendor contact. Ideally
this entire subtree would be in src/contrib, but if that isn't going
to happen at least this has a chance of warning off unsuspecting
committers.

$Id$ -> $FreeBSD$

Merge changes from vendor branch (tzcode1999a), plus the following additional
changes:

- Finish migrating zic to its own private.h.
- Fix zic.8 so that it really is written in -mdoc.
- Add four new flags to zic (&document):
-D don't create directories
-u change ownership of newly-created files to user
-g change ownership of newly-created files to group
-m change mode of newly-created files to modespec
These, once proven, can be used to clean up the installation.

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.

FreeBSD port of timezone code.
