Add support for "tp" format.  tp was the standard system
archiver for Fourth Edition through Sixth Edition Unix; it was
replaced by tar in Seventh Edition.  (First Edition through
Third Edition used "tap.")

Unfortunately, tp was not so very standard; there were a
few different variants.  The code here attempts to support
what I believe were the most common variants.

tp support is not yet enabled by archive_read_support_format_all(),
as I'm not yet entirely comfortable with the detection
heuristics.  People interested in experimenting can
add archive_read_support_format_tp() just after any calls
to archive_read_support_format_all() in bsdtar to see how
well this works.

TODO: tp format is roughly similar in structure to dump/restore
   archive formats used by many systems.  It should be possible
   to generalize this code to handle many dump/restore variants.
   Format detection heuristics are going to be rough, though.

Thanks to: Warren Toomey, whose very basic tp extraction programs
   and documentation made this possible.
