kernel memory management revisited (phase 2): map physical memory according to zones

  • ia32: register reserved and ACPI zones
  • pareas are now used only for mapping of present physical memory (hw_area() is gone)
  • firmware zones and physical addresses outside any zones are allowed to be mapped generally
  • fix nasty antient bug in zones_insert_zone()
  • Property mode set to 100644
