GIT: unionfs2-2.6.27.y: Unionfs: support incremental versions

    Unionfs: support incremental versions
    
    Also: release Unionfs 2.1 (since code has gotten much more stable since 2.0)
    
    Unionfs will now report its precise version number and the kernel it was
    meant for, upon module loading.  This is useful for maintenance purposes:
    users can report the precise release number of Unionfs, and it also helps
    prevent running older versions when newer ones are intended, or mixing
    versions among supported kernels.
