Nathan Binkert 3ece6ab029 New and improved configuration mechanism. No more writing of
wierd ini files.  The ini files are still used as an intermediate step,
but a sophisticated python library exists to help build them more
easily.

SConscript:
    add the new embedded file stuff
    remove all of the old object description junk
base/inifile.cc:
base/inifile.hh:
    get rid of findDefault and findAppend since they were the source
    of much evil.
base/trace.cc:
    For now, if we don't have the dprintf_stream set up, dump
    to standard out.  We probably want a command line option
    for this.
dev/alpha_console.cc:
    PioDevice now takes a platform parameter.
    All PioDevices must have a pio_latency parameter.  We stick
    a dummy parameter in here for now until we get rid of the
    builder stuff.
dev/alpha_console.hh:
    don't need Platform anymore
dev/baddev.cc:
    PioDevice now takes a platform parameter.
    All PioDevices must have a pio_latency parameter.  We stick
    a dummy parameter in here for now until we get rid of the
    builder stuff. Same for the platform parameter, though we just
    pass the PioDevice a null parameter since it isn't used by
    this device and it's quicker.
dev/baddev.hh:
    fix #include guards
dev/etherlink.cc:
    rename parameters.
dev/ethertap.cc:
    rename parameters
dev/ide_ctrl.cc:
    All devices need an address even if it will get overwritten later.
dev/ide_disk.cc:
    use an enum for the drive ID stuff.
    rename disk_delay -> delay
    Actually, I think that we should implement "cable select" and
    have the controller tell the drive what it is.
dev/io_device.cc:
dev/io_device.hh:
    All IO devices take a Platform *
dev/ns_gige.cc:
    all devices need an io_bus.  rename header_bus to io_bus
    We don't need stuff for the interrupt controller since
    it's all in the platform now.
dev/ns_gige.hh:
    We don't need stuff for the interrupt controller now since
    it's all in the platform.
dev/pciconfigall.cc:
    Pass a dummy NULL to the PioDevice for the platform since
    we don't need one.
dev/pcidev.cc:
    Move a bunch of common functionality into the PciDev
dev/platform.hh:
    remove unneeded code
dev/tsunami.cc:
    remove unused param
dev/tsunami_cchip.cc:
    pass platform pointer
dev/tsunami_io.cc:
dev/tsunami_pchip.cc:
dev/uart.cc:
    pass platform variable
dev/uart.hh:
    don't need to keep a platform pointer.  it's in the base class
kern/linux/linux_system.cc:
kern/tru64/tru64_system.cc:
    rename some parameters
sim/builder.cc:
    clean up builder code. use more parameters from the
    config node.  all sections with a type= are now created,
    the old mechanisms no longer work
sim/builder.hh:
    remove some extra variables since they are found in the ConfigNode
sim/main.cc:
    add a quick hack command line argument -X to dump out the
    embedded files.  (probably should be fixed up a little.)
    accept .mpy files
    printing to the streams has to happen after the hierarchy
    is built since we're moving away from param contexts
sim/param.cc:
    add parsing support for ranges
sim/process.cc:
    isValid isn't very useful anymore.  interpret the names
    stdout, stderr, cout, cerr for the file descriptors
sim/pyconfig/SConscript:
    Add Action handlers for creating an embedded python file
    and for creating an embedded C file.

    use these action handlers to embed all objects found in the objects
    tree into the binary along with the importer and the m5config stuff
sim/pyconfig/m5config.py:
    Major changes to the original configuration file generator.  These
    changes largely involve implementing copy-on-write like semantics
    for all of the SimObjects.  Real documentation must be written.
sim/universe.cc:
    Universe becomes a SimObject since we don't really have the notion of
    param contexts in the python code.
