Sync up with OpenBSD. Too many changes to note, but the major features

are:
* Implement cpio compatibility mode when pax is invoked as cpio
* Extend tar compatibility mode to cover many of the GNU tar single-letter
  options (bzip2 mode, aka -y/-j is not present in OpenBSD).  When
  invoked as tar, pax is now full-featured enough for use by the ports
  collection to extract distfiles and create packages.
* Many bug fixes to the operation of pax and the tar compatibility modes
* Code fixes for things like correct string buffer termination.

I tried to preserve existing FreeBSD fixes to this utility; please let me
know if I have inadvertently spammed something.
