Changes in version 0.9:

Multi-threaded '-t, --list' has been implemented. See chapter 'Limitations
of parallel tar decoding' in the manual for details.

The new option '-n, --threads', which sets the number of decompression
threads, has been added.

Tarlz now recognizes global pax headers, but for now ignores them.

Tarlz now decodes numerical fields in headers using length-safe parsers
instead of strtoul to prevent the parser from exceeding the end of the field
if it does not contain a terminating character.

The new chapter 'Limitations of parallel tar decoding' has been added to the
manual.
