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.
