Update to 1.0.4:

Changes in 1.0.4 (Dec 21, 2008)
- Added support to use pbzip2 with tar (--use-compress-prog=pbzip2).
- Added support for all remaining bzip2 command line options so
  pbzip2 can be used as a drop-in replacement for bzip2.
- Fixed bug that would cause pbzip2 to crash if detection of the
  number of processors failed.
- Now prevents uclibc from being exposed to its lack of a
  getloadavg function.

Changes in 1.0.3 (Oct 31, 2008)
- Added support for compression using stdin and pipes!  Thanks
  to Ivan Voras for supplying the patch to enable this feature.
- Added support for decompression using stdin and pipes but
  currently limited to only a single thread
- Added support for testing bzip2 files using stdin and pipes
- Added support to directly decompress files without using
  threads when files are small or the system only has 1 CPU.
  This mode is also used if the .bz2 file contains only 1
  bzip2 stream.
- Added support to compress 0 byte files like bzip2
- Added support for pbzcat symlink to automatically specify
  decompression mode to stdout, just like bzcat
- Increased max supported path and filename from 255 to 2048
  characters
- Updated RPM spec to support SUSE Linux
- Updated help display to show how many CPUs autodetect has found
- Code cleanup
