Changes in version 0.5:

A simplified posix pax format has been implemented. Tarlz can now store,
list and extract:
  - files with unlimited name size
  - links to files with unlimited name size
  - files of unlimited size

A CRC32-C (Castagnoli) of the extended header data has been implemented.
This fixes a serious flaw in the posix pax format. A CRC was chosen
because a checksum is too weak for a potentially large list of variable
sized records. A checksum can't detect simple errors like the swapping
of two bytes.

The new option '--ignore-crc' has been added.

Missing #includes for major, minor and makedev have been added.

The new archive format has been documented in the manual.
