Re [Cygwin PATCH */9] tzcode resync -- for discussion only

[Mark Geisert]

I'm not absolutely sure yet but I think this patch set isn't complete. 
What's been posted is OK for discussion (on cygwin-developers?) but would 
need to be augmented if you're going to apply as-is.

I had a git commit/revert mishap and these are recovered file versions.  I 
belatedly discovered there's no record in the patches of my creating 
directory winsup/cygwin/tzcode or of my deleting localtime.cc and 
tz_posixrules.h from winsup/cygwin in my local repository.

When it becomes time to submit the final patch versions, I'll do so from a 
brand new repository.  Sorry for any confusion.
