Changes for version 2.01
- cleaned up for 64bit, HPUX PA-RISC 2.0W and itanium
- fleshed out the Compress::Zlib compatibility, added a couple of tests for it.
- added bzip2, bunzip2 and bzcat, which act like the bzip commands.
- added some compatibility for windows, can't test it out really
- added the bzlib library underneath
- changed the test suite so that it does not rely on bzip2 being installed.
- added a test to the Makefile.PL to determine whether or not the internal Bzlib is necessary.
- Compress::Bzip2 - Interface to Bzip2 compression library
