e8ace88e89 create base/fenv.c to standerdize fenv across platforms. It's a c file and not a cpp file because c99
(which defines fenv) doesn't necessarily extend to c++ and it is a problem with solaris. If really
desired this could wrap the ieeefp interface found in bsd* as well, but I see no need at the moment.

a575fbd4aa Completely re-work how the scons framework incorporates swig
and python code into m5 to allow swig an python code to
easily added by any SConscript instead of just the one in
src/python.  This provides SwigSource and PySource for
adding new files to m5 (similar to Source for C++).  Also
provides SimObject for including files that contain SimObject
information and build the m5.objects __init__.py file.

eefbda7f7c Don't allow Source to accept multiple arguments, lists,
or automatically do Split().  It isn't used anywhere, and
isn't very consistent with the python features that are
about to be added.  Do accept SCons.Node.FS.File arguments
though.

e04208f046 Fix NextEthernetAddr.
unproxy() needs to return a new object otherwise all
instances will use the same value.  This fix is more
or less unique to NextEthernetAddr because its use of
the proxy stuff is a bit different than everything else.
