python: Move various utility classes into a new m5.util package so

they're all in the same place.  This also involves having just one
jobfile.py and moving it into the utils directory to avoid
duplication.  Lots of improvements to the utility as well.

--HG--
rename : src/python/m5/attrdict.py => src/python/m5/util/attrdict.py
rename : util/pbs/jobfile.py => src/python/m5/util/jobfile.py
rename : src/python/m5/util.py => src/python/m5/util/misc.py
rename : src/python/m5/multidict.py => src/python/m5/util/multidict.py
rename : util/stats/orderdict.py => src/python/m5/util/orderdict.py
