pcp v2

New features:

• Improved directory walk implementation. The intial file and directory scan now runs in parallel, massively increasing performance.
• Single large files are now split into chunks and copied and checksummed in parallel. This gives us better load balancing between processes, and increases performance.
• "cp -u" update copy functionality. You can now tell pcp to only copy files that have changed since the last copy.
