New directory structure:

- simulator source now in 'src' subdirectory
- imported files from 'ext' repository
- support building in arbitrary places, including
outside of the source tree.  See comment at top
of SConstruct file for more details.
Regression tests are temporarily disabled; that
syetem needs more extensive revisions.

SConstruct:
    Update for new directory structure.
    Modify to support build trees that are not subdirectories
    of the source tree.  See comment at top of file for
    more details.
    Regression tests are temporarily disabled.
src/arch/SConscript:
src/arch/isa_parser.py:
src/python/SConscript:
    Update for new directory structure.
