    kernel - Adjust emergency pager, add D_NOEMERGPGR
    
    * Adjust emergency pager and pager thread tests a little.  Allow the
      emergency pager to also page to VCHR devices as long as D_NOEMERGPGR
      is not flagged.
    
    * Add the D_NOEMERGPGR flag and apply to "vn" and "mfs" block devices.
