tarlz: 0.26 -> 0.27.1

[ehmry]

Changes in version 0.27:

• tarlz now prints seconds since epoch if a file date is out of range.

• tarlz now uses at least 4 digits to print years.

• 'tarlz -tv' now prints the value of typeflag after the member name for
  unknown file types.

• tarlz now prints a diagnostic when it finds a corrupt tar header (or
  random data where a tar header is expected).

• tarlz now diagnoses CRC mismatches in extended records separately.

• Multi-threaded decoding now prints diagnostics about CRC mismatches and
  unknown keywords in extended records in the correct order.

• Many small fixes and improvements have been made to the code and the
  manual.

• The chapter 'Creating backups safely' has been added to the manual.
  (Suggested by Aren Tyr).

• Lzip is now required to run the tests because I have not found any
  other portable and reliable way to tell compressed archives from non-compressed.

• Where possible, .tar archives for the testsuite are now decompressed
  from their .tar.lz versions instead of distributed.

• 'make check' no longer tests '--mtime' with extreme dates to avoid test
  failures caused by differences with the system tool 'touch'. (Reported by
  Aren Tyr).

• 5 new test files have been added to the testsuite.
