wollman 704d828247 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.
