constructors. There is no backward compatibility. Not everything has
been tested.
* aiff.{py,doc}: deleted in favor of aifc.py (which contains its docs as
comments)
Added runcall(func, *args) interfaces to profile.py, bdb.py, pdb.py, wdb.py
Added new module bisect.py and used it in sched.py.
Mostly cosmetic changes to profile.py (changed output format).
