Adding some definitons for read/write blob/string.  I need to locate te code stever wrote to break up address ranges into blk/page size chunks.

cpu/simple/cpu.cc:
cpu/simple/cpu.hh:
    Add read/write blob definitions, still need to break it up into blk size chunks (where was the code stever wrote for that?)
mem/physical.hh:
    Remove un-needed function (I think)
mem/port.hh:
    Default these virtual functions to panic unimplented
mem/translating_port.cc:
    Again handling read/write string properly.

    Need the stever code to break things into page size chunks yet
mem/translating_port.hh:
    Having trouble with the const declerator.  I will need to read how it works, for now it compiles if I remove it.
