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
