5a1eb9049d Support for Serializable non-SimObject things like events.
Can now serialize & unserialize DmaRequestEvents and DmaTransferEvents.
Also support serialize/unserialize of pointers to SimObjects and
other Serializable objects.

    Put ExecContext in its own section so its _status fields doesn't conflict.

sim/eventq.hh:
    unserialize() now takes a Checkpoint* instead of an IniFile*.
    Events get serialized by the event queue only if they're marked
    as AutoSerialize... others are assumed to be serialized by something
    else (e.g. an owning SimObject) or to not matter.
sim/param.cc:
    Shift 'const' in case T is a ptr type.
sim/serialize.cc:
sim/serialize.hh:
    Define Checkpoint object to encapsulate everything you need to know
    about a checkpoint.  Use it to allow lookups of named Serializable
    objects (and SimObjects) during unserialization.
    unserialize() now takes a Checkpoint* instead of an IniFile*.

1511370d09 More progress on checkpointing... we can now write out a checkpoint and read it back in,

91cb532f9f Make FullCPU schedule its TickEvent when one of its contexts becomes active.
This fixes detailed-mpboot, which was broken as of my last change.
Also clean up some of the ExecContext status initialization.

cpu/base_cpu.hh:
    CPU::execCtxStatusChg() now takes thread_num as an arg so the CPU knows
    which execContext had the status change.
    BaseCPU::registerExecContexts() no longer needs to be virtual.
cpu/exec_context.cc:
    Initialize _status directly... don't use setStatus() as this will notify the CPU
    of the change before it is ready.
    CPU::execCtxStatusChg() now takes thread_num as an arg so the CPU knows
    which execContext had the status change.
cpu/exec_context.hh:
    Don't need initStatus() any more.
cpu/simple_cpu/simple_cpu.cc:
    Move execCtxStatusChg() from header to .cc file.
    No longer need specialized version of registerExecContexts to schedule TickEvent.
cpu/simple_cpu/simple_cpu.hh:
    Move execCtxStatusChg() from header to .cc file.
    CPU::execCtxStatusChg() now takes thread_num as arg (must be 0 for SimpleCPU).
    No longer need specialized version of registerExecContexts to schedule TickEvent.
kern/tru64/tru64_system.cc:
    Don't need initRegs; the PC etc. get initialized in the CPU constructor.
    ExecContexts start out as Unallocated, so no need to set them to Unallocated here.
kern/tru64/tru64_system.hh:
    Don't need initRegs; the PC etc. get initialized in the CPU constructor.
sim/prog.cc:
    ExecContexts start out as Unallocated, so no need to set them to Unallocated here.

f5da73b688 Initial support for CPU switching. New SamplingCPU object encompasses a set
of CPUs that get switched round-robin (though currently we're only shooting for
two CPUs and one switch event, and even that doesn't quite work yet).  Registration
of ExecContexts with System/Process object factored out so we can create two CPUs
but only register one of them at a time.  Also worked at making behavior and naming
in System and Process objects more consistent.

arch/alpha/ev5.cc:
    Rename ipr_init to initIPRs and get rid of unused mem arg.
arch/alpha/fake_syscall.cc:
    Process:numCpus is now a function (not a data member).

cpu/simple_cpu/simple_cpu.cc:
    Support for ExecContext switching.
    Renamed contexts array to execContexts to be consistent with Process.
    CPU ID now auto-assigned by system object.
    Cleaned up MP full-system initialization a bit.

    Renamed xcvec array to execContexts to be consistent with Process.
