  Log:
  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.
