    kernel - Add uid, gid, and inum to stat data for pipes
    
    * fstat(pipefd) now populations additional fields. uid, gid,
      and inum.  In-line with other BSDs and Linux.  Not sure why
      any program would use the inum field but... now its populated.
    
    * Add an anonymous inode allocator to the pcpu structure.  No
      atomic ops required.  Basically just does:
    
      pipe->inum = gd->gd_anoninum++ * ncpus + gd->gd_cpuid + 2;
    
    * Facility can be used for other things as needed.
