switching from tp_getattr to tp_getattro.

This now uses the new gotofileline() method defined in FileList.py.

rather than the idle.py script.  This has advantages and
disadvantages; the biggest advantage being that we can more easily
have an alternative main program.

Add gotofileline(), a convenience method which I intend to use in a
variant.

Rename test() to _test().

Allow module getattr and setattr to exploit string interning, via the
previously null module object tp_getattro and tp_setattro slots.   Yields
a very nice speedup for things like random.random and os.path etc.

When getting a string buffer for a string we just created, use
PyString_AS_STRING() instead of PyString_AsString() to avoid the
call overhead and extra type check.

This closes bug #417418.

Finish the last set of changes to these files so the conversion does not
break.

For rich comparisons, use instance_getattr2() when possible to avoid
the expense of setting an AttributeError.  Also intern the name_op[]
table and use the interned strings rather than creating a new string
and interning it each time through.

Remove unused import of "sys".

If the file TESTFN exists before we start, try to remove it.

Add spaces around the = in some assignments.

should be used for classes which only exist to act as containers rather
than as factories for instances.

doesn't know how to do LE, LT, GE, GT.  dict_richcompare can't do the
latter any faster than dict_compare can.  More importantly, for
cmp(dict1, dict2), Python *first* tries rich compares with EQ, LT, and
GT one at a time, even if the tp_compare slot is defined, and
dict_richcompare called dict_compare for the latter two because
it couldn't do them itself.  The result was a lot of wasted calls to
dict_compare.  Now dict_richcompare gives up at once the times Python
calls it with LT and GT from try_rich_to_3way_compare(), and dict_compare
is called only once (when Python gets around to trying the tp_compare
slot).
Continued mystery:  despite that this cut the number of calls to
dict_compare approximately in half in test_mutants.py, the latter still
runs amazingly slowly.  Running under the debugger doesn't show excessive
activity in the dict comparison code anymore, so I'm guessing the culprit
is somewhere else -- but where?  Perhaps in the element (key/value)
comparison code?  We clearly spend a lot of time figuring out how to
compare things.

A Mystery:  test_mutants ran amazingly slowly even before dictobject.c
"got fixed".  I don't have a clue as to why.  dict comparison was and
remains linear-time in the size of the dicts, and test_mutants only tries
100 dict pairs, of size averaging just 50.  So "it should" run in less than
an eyeblink; but it takes at least a second on this 800MHz box.

and wrap the body in try/finally to ensure TESTFN gets cleaned up no
matter what.
