Rework the command line paramters for python output and how

output files and the output directory are are handled.  Make
the output directory configuration via a command line parameter,
or an environment variable.

SConscript:
    Add new output file stuff
base/misc.cc:
dev/simconsole.cc:
    use new output file code
cpu/base_cpu.cc:
    use new output file code to generate output streams
dev/etherdump.cc:
    use the output file code to find the output directory
    use a real stream instead of a pointer
dev/etherdump.hh:
    use a real stream instead of a pointer
objects/Root.mpy:
    output_dir and config_output_file are not longer configured here.
sim/main.cc:
    - Completely rework the command line argument passing to deal with
    changes in python and output files.
    - Update help output to reflect changes.
    - Remove all direct support for .ini files.  They are strictly
    for intermediate representation.
    - Remove the --foo:bar=blah syntax for .ini files and add --foo.bar=blah
    syntax for python.  This will generate: foo.bar = 'blah' in the python
    script.
    - Add '-d' to set the output directory.
    - Use new output file code to access the output stream.
sim/serialize.cc:
    use the new code to find the output directory
sim/universe.cc:
    Get rid of makeOutputStream.  Use the new output file code.
    Remove output_dir and config_output_file as parameters.
