Ali Saidi e196d20d9d Make TranslatingPort be a type of Port rather than something special
arch/alpha/arguments.cc:
    rather than returning 0, put a panic in... it will actually make us fix
    this rather than scratching our respective heads
base/loader/object_file.cc:
base/loader/object_file.hh:
    Object loader now takes a port rather than a translating port
cpu/cpu_exec_context.cc:
cpu/cpu_exec_context.hh:
sim/process.cc:
    Make translating port a type of port rather than anything special
cpu/simple/cpu.cc:
    no need to grab a port from the cpu anymore
mem/physical.cc:
    add an additional type of port to physicalmemory called "functional"
    Only used for functional accesses (loading binaries/syscall emu)
mem/port.hh:
    make readBlok/writeBlob virtual so translating port can do the
    translation first
mem/translating_port.cc:
mem/translating_port.hh:
    Make TranslatingPort inherit from Port
sim/system.cc:
    header file that doesn't exit removed
