Sync code with tzcode2010m

asctime.c:
* Set errno to EINVAL and return "??? ??? ?? ??:??:?? ????\n" if
asctime_r is called with a NULL struct tm pointer. (Note that
asctime_r is called by ctime_r and asctime; asctime is called by
ctime.)

localtime.c:
* Set errno to EINVAL and return WRONG if time1 is called with a
NULL struct tm pointer; avoid dereference if a NULL struct tm
pointer is passed to timelocal, timegm, or timeoff. (Note that
time1 is called by mktime, timegm, and timeoff; mktime is called
by timelocal.)
* more core-avoidance work
* Change to set timezone and altzone based on time types with
greatest transition times (for the benefit of Asia/Seoul).

zic.8:
* Warning about case-sensitivity of names, but not of abbrevations

zic.c:
* Conditionally output extra types with most-recently-use offsets
last (for use by systems with pre-2011 versions of localtime.c,
helping to ensure that globals "altzone and "timezone" get set
correctly).

The code has been running for nearly four weeks on my laptop running
FreeBSD 8.1 without a problem.

Make mandoc/mdocml happy.

Copy usr.sbin/zic to contrib/tzcode/zic for the proper split of
contributed code and FreeBSD specific code.

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.

Finish a few more .Dl "quoted" arguments missed in revision 184984

Add missing quotes to .Dl arguments.

This is harmless for the mandoc output, but it makes syntax highlighting of
the .Dl argument string a bit prettier in Emacs.

Expand contractions.

Eliminate macro calls inside literal displays.

Mechanically kill hard sentence breaks.

Merge changes from the tzcode2004a import.

The .Nm utility

Prepare for mdoc(7)NG.

mdoc(7) police: use canonical form of .Dd macro.

mdoc(7) police: use the new features of the Nm macro.

Spelling. Add missing .El.

Fix a bunch of broken cross-references

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.

Replace use of obsolete .q groff macro with .Dq

Merge from vendor branch. We are now completely up-to-date with
respect to the ADO timezone code.
