Simple program runs with sendAtomic!

Ignoring returned latency for now.
Refactored loadSections in ObjectFile hierarchy.

base/loader/aout_object.cc:
base/loader/aout_object.hh:
base/loader/ecoff_object.cc:
base/loader/ecoff_object.hh:
base/loader/elf_object.cc:
base/loader/elf_object.hh:
base/loader/object_file.hh:
    Have each section record a pointer to image data.
    This allows us to move common loadSections code into ObjectFile.
base/loader/object_file.cc:
    Have each section record a pointer to image data.
    This allows us to move common loadSections code into ObjectFile.
    Also explicitly load BSS now since we need to allocate the
    translations for it in syscall emulation.
cpu/base.hh:
    Don't need memPort (just pass port in to ExecContext constructor).
cpu/exec_context.cc:
cpu/exec_context.hh:
mem/port.cc:
mem/translating_port.cc:
mem/translating_port.hh:
    Pass syscall emulation Port into constructor instead of
    getting it from BaseCPU.
cpu/simple/cpu.cc:
    Explicitly choose one of three timing models.
    Statically allocate request and packet objects when possible.
    Several more minor bug fixes.
    Works for simple program with SIMPLE_CPU_MEM_IMMEDIATE model now.
    Probably have memory leaks with SIMPLE_CPU_MEM_TIMING (if it works at all).
    Pass syscall emulation Port into constructor instead of
    getting it from BaseCPU.
cpu/simple/cpu.hh:

    Pass syscall emulation Port into constructor instead of

mem/physical.cc:
    Set packet result field.
