* Extraction and listing of Unix symbolic links is now supported.
* Decompression code for the "old" PMarc archive algorithm (-pm1-) has
been added.
* Support has been added for Unix LHA level 0 header extended areas
(so level 0 archives with Unix metadata are now listed and extracted
correctly).
* The Unix permissions field in the list output for directory entries
has been fixed.
* The library header files have been fixed so that they can be included
in C++ code.
* The LHADecoder interface, for extracting raw compressed data, has been
added to the public header files.
* The Unix LHA test archives have been regenerated and improved.
* A "ghost testing" tool has been added for testing ghost compression
algorithms such as -pm1-.
* The list output tests have been fixed to be repeatable regardless of
the current date.
* Build of the fuzzer tool has been fixed.
