  Log:
  Merge kern_descrip.c:1.322, user.h:1.74, procstat_files.c:1.5:
  
    Add support for displaying a process' current working directory, root
    directory, and jail directory within procstat.  While this functionality
    is available already in fstat, encapsulating it in the kern.proc.filedesc
    sysctl makes it accessible without using kvm and thus without needing
    elevated permissions.
  
    The new procstat output looks like:
  
      PID COMM               FD T V FLAGS    REF  OFFSET PRO NAME
      76792 tcsh            cwd v d --------   -       - -   /usr/src
      76792 tcsh           root v d --------   -       - -   /
      76792 tcsh             15 v c rw------  16    9130 -   -
      76792 tcsh             16 v c rw------  16    9130 -   -
      76792 tcsh             17 v c rw------  16    9130 -   -
      76792 tcsh             18 v c rw------  16    9130 -   -
      76792 tcsh             19 v c rw------  16    9130 -   -
  
    I am also bumping __FreeBSD_version for this as this new feature will be
    used in at least one port.

  Note that in the MFC, __FreeBSD_version is not bumped as we will bump it
  once (shortly) for all procstat(1) MFC changes together.
