MFV of tzcode2009e:

Upgrade of the tzcode from 2004a to 2009e.

Changes are numerous, but include...

- New format of the output of zic, which supports both 32 and 64
bit time_t formats.

- zdump on 64 bit platforms will actually produce some output instead
of doing nothing for a looooooooong time.

- linux_base-fX, with X >= at least 8, will work without problems related
to the local time again.

The original patch, based on the 2008e, has been running for a long
time on both my laptop and desktop machine and have been tested by
other people.

After the installation of this code and the running of zic(8), you
need to run tzsetup(8) again to install the new datafile.

Back out WARNS cleanup: this is apparently vendor code, even though
most of the files aren't on the vendor branch.

-Wall cleaning

$Id$ -> $FreeBSD$

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.

Second part of the timezone code import for version 96h. This includes
a number of bug fixes to the compiler (which bugs would previously
have caused undesirable behavior during transition times).

The latest and greatest timezone code from Arthur David Olson, part 1.
This import comprises the `zic' and `zdump' programs.
