Remove all of the Tru64 specific stuff from the base System object

into its own Tru64System object.  Also remove the System builder
stuff and create a Tru64System builder.  This makes it much
simpler to support more operating systems.

arch/alpha/ev5.cc:
    Each system provides its own mechanism for doing a breakpoint.
base/remote_gdb.hh:
    #include <map>
cpu/pc_event.cc:
cpu/pc_event.hh:
    Separate out System specific PCEvents
cpu/simple_cpu/simple_cpu.cc:
    each system provides its own init script
kern/tru64/dump_mbuf.cc:
kern/tru64/printf.cc:
    Stick this in a namespace
