mm: oom analysis: add per-zone statistics to show_free_areas()

Browse source 
show_free_areas() displays only a limited amount of zone counters.  This
patch includes additional counters in the display to allow easier
debugging.  This may be especially useful if an OOM is due to running out
of DMA memory.
