Message:

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()
