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.

-# M5 Python Configuration Utility
-#
-# The basic idea is to write simple Python programs that build Python
-# objects corresponding to M5 SimObjects for the deisred simulation
-# configuration.  For now, the Python emits a .ini file that can be
-# parsed by M5.  In the future, some tighter integration between M5
-# and the Python interpreter may allow bypassing the .ini file.
-#
-# Each SimObject class in M5 is represented by a Python class with the
-# same name.  The Python inheritance tree mirrors the M5 C++ tree
-# (e.g., SimpleCPU derives from BaseCPU in both cases, and all
-# SimObjects inherit from a single SimObject base class).  To specify
-# an instance of an M5 SimObject in a configuration, the user simply
-# instantiates the corresponding Python object.  The parameters for
-# that SimObject are given by assigning to attributes of the Python
-# object, either using keyword assignment in the constructor or in
-# separate assignment statements.  For example:
-#
-# cache = BaseCache('my_cache', root, size=64*K)
-# cache.hit_latency = 3
-# cache.assoc = 8
-#
-# (The first two constructor arguments specify the name of the created
-# cache and its parent node in the hierarchy.)
-#
-# The magic lies in the mapping of the Python attributes for SimObject
-# classes to the actual SimObject parameter specifications.  This
-# allows parameter validity checking in the Python code.  Continuing
-# the example above, the statements "cache.blurfl=3" or
-# "cache.assoc='hello'" would both result in runtime errors in Python,
-# since the BaseCache object has no 'blurfl' parameter and the 'assoc'
-# parameter requires an integer, respectively.  This magic is done
-# primarily by overriding the special __setattr__ method that controls
-# assignment to object attributes.
-#
-# The Python module provides another class, ConfigNode, which is a
-# superclass of SimObject.  ConfigNode implements the parent/child
-# relationship for building the configuration hierarchy tree.
-# Concrete instances of ConfigNode can be used to group objects in the
-# hierarchy, but do not correspond to SimObjects themselves (like a
-# .ini section with "children=" but no "type=".
-#
-# Once a set of Python objects have been instantiated in a hierarchy,
-# calling 'instantiate(obj)' (where obj is the root of the hierarchy)
-# will generate a .ini file.  See simple-4cpu.py for an example
-# (corresponding to m5-test/simple-4cpu.ini).
-#
-#####################################################################

-#####################################################################
-#
-# ConfigNode/SimObject classes
-#
-# The Python class hierarchy rooted by ConfigNode (which is the base
-# class of SimObject, which in turn is the base class of all other M5
-# SimObject classes) has special attribute behavior.  In general, an
-# object in this hierarchy has three categories of attribute-like
-# things:
-#
-# 1. Regular Python methods and variables.  These must start with an
-# underscore to be treated normally.
-#
-# 2. SimObject parameters.  These values are stored as normal Python
-# attributes, but all assignments to these attributes are checked
-# against the pre-defined set of parameters stored in the class's
-# _param_dict dictionary.  Assignments to attributes that do not
-# correspond to predefined parameters, or that are not of the correct
-# type, incur runtime errors.
-#
-# 3. Hierarchy children.  The child nodes of a ConfigNode are stored
-# in the node's _children dictionary, but can be accessed using the
-# Python attribute dot-notation (just as they are printed out by the
-# simulator).  Children cannot be created using attribute assigment;
-# they must be added by specifying the parent node in the child's
-# constructor or using the '+=' operator.
-
-# The SimObject parameters are the most complex, for a few reasons.
-# First, both parameter descriptions and parameter values are
-# inherited.  Thus parameter description lookup must go up the
-# inheritance chain like normal attribute lookup, but this behavior
-# must be explicitly coded since the lookup occurs in each class's
-# _param_dict attribute.  Second, because parameter values can be set
-# on SimObject classes (to implement default values), the parameter
-# checking behavior must be enforced on class attribute assignments as
-# well as instance attribute assignments.  Finally, because we allow
-# class specialization via inheritance (e.g., see the L1Cache class in
-# the simple-4cpu.py example), we must do parameter checking even on
-# class instantiation.  To provide all these features, we use a
-# metaclass to define most of the SimObject parameter behavior for
-# this class hierarchy.
-#
-#####################################################################
-
-# The metaclass for ConfigNode (and thus for everything that derives
-# from ConfigNode, including SimObject).  This class controls how new
-# classes that derive from ConfigNode are instantiated, and provides
-# inherited class behavior (just like a class controls how instances
-# of that class are instantiated, and provides inherited instance
-# behavior).

-    # in the body of the class definition get loaded into the class's

-    # __new__ (starting with underscore).

-        return super(MetaConfigNode, cls).__new__(cls, name, bases, priv_dict)
-
-    # initialization: start out with an empty param dict (makes life
-    # simpler if we can assume _param_dict is always valid).  Also
