        - speedups in printer queue enumeration  - still room for
          improvement.  The construct_dev_mode() still creates and destroys
          a printer info_2 structure every time it is called.
        - fixed job->devmode memory leak
        - converted printer job notification routines to use tallocated
          memory rather than a fixed 2K buffer.   This reduces the memory
          requirements of a 4500 job queue enumeration from 90MB to about
          16MB.
