Summary: make file object an iterator

Initial Comment:
As per python-dev discussion july 17 2002 & earlier, I 
reworked Oren's patch to remove a reference loop 
between file object and xreadlines object (making the 
reference xreadl.->fileob non-addref'd when and only
when the xreadlines object is being internally held by
the fileob), make f.readline interop with f.next (the former
delegating to the latter iff f is holding an xreadl. obj), make
f.seek remove the xreadl.obj that f is holding (if any), and
removing the optimization of caching xreadlines function
pointers as static variables in functions of fileobject.c.

Also added tests for this functionality to test_file.py.

I'll close this as "duplicate". Oren has since submitted a
better patch that re-implements the needed buffering in the
file object without the need to reference xreadlines at all.
That sounds like a better solution.
