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.
