Guido van Rossum 59d1d2b434 Iterators phase 1. This comprises: 
new slot tp_iter in type object, plus new flag Py_TPFLAGS_HAVE_ITER
new C API PyObject_GetIter(), calls tp_iter
new builtin iter(), with two forms: iter(obj), and iter(function, sentinel)
new internal object types iterobject and calliterobject
new exception StopIteration
new opcodes for "for" loops, GET_ITER and FOR_ITER (also supported by dis.py)
new magic number for .pyc files
new special method for instances: __iter__() returns an iterator
iteration over dictionaries: "for x in dict" iterates over the keys
iteration over files: "for x in file" iterates over lines

TODO:

documentation
test suite
decide whether to use a different way to spell iter(function, sentinal)
decide whether "for key in dict" is a good idea
use iterators in map/filter/reduce, min/max, and elsewhere (in/not in?)
speed tuning (make next() a slot tp_next???)

Guido van Rossum 823649d544 Move the code implementing isinstance() and issubclass() to new C 
APIs, PyObject_IsInstance() and PyObject_IsSubclass() -- both
returning an int, or -1 for errors.

Marc-André Lemburg ad7c98e264 This patch adds a new builtin unistr() which behaves like str() 
except that it always returns Unicode objects.

A new C API PyObject_Unicode() is also provided.

This closes patch #101664.

Guido van Rossum c4a19e7fe9 Remobe beopen/cnri/cwi copyrights, according to CNRI instructions. 
This doesn't change the copyright status for these files -- just the
markings!  Doing it on the main branch for these three files for which
the HEAD revision was pushed back into 1.6.

Marc-André Lemburg cf5f358784 Restore PyXXX_Length() APIs for binary compatibility. 
New code will see the macros and therefore use the PyXXX_Size()
APIs instead.

Thomas Wouters 7e47402264 Spelling fixes supplied by Rob W. W. Hooft. All these are fixes in either 
comments, docstrings or error messages. I fixed two minor things in
test_winreg.py ("didn't" -> "Didn't" and "Didnt" -> "Didn't").

There is a minor style issue involved: Guido seems to have preferred English
grammar (behaviour, honour) in a couple places. This patch changes that to
American, which is the more prominent style in the source. I prefer English
myself, so if English is preferred, I'd be happy to supply a patch myself ;)
