Proposed patch to sync tz from upstream

[Paul Eggert <eggert at cs dot ucla dot edu>]

I noticed that the timezone files contained some non-UTF-8 text and 
thought I'd fix that the simplest way I could think of, namely by 
upgrading to the current version of the upstream code and data (which 
has standardized on UTF-8).  The patch is fairly large (mostly just 
mindless copying from tz) so I've compressed it in the 2nd attachment to 
this email.  The 1st attachment contains the interesting bits, i.e., the 
parts not simply copied from the tz code and data, or simply deleted.
