Closes: #556025 seg fault when doing list(xrange(1e9))
A MemoryError is now raised when the list cannot be created.
There is a test, but as the comment says, it really only
works for 32 bit systems. I don't know how to improve
the test for other systems (ie, 64 bit or systems
where the data size != addressable size,
e.g. 64 bit data, but 48 bit addressable memory)

Jim Fulton reported a segfault in dir(). A heavily proxied object
returned a proxy for __class__ whose __bases__ was also a proxy. The
merge_class_dict() helper for dir() assumed incorrectly that __bases__
would always be a tuple and used the in-line tuple API on the proxy.

backport tim_one's patch:
Repair widespread misuse of _PyString_Resize. Since it's clear people
don't understand how this function works, also beefed up the docs. The
most common usage error is of this form (often spread out across gotos):
if (_PyString_Resize(&s, n) < 0) {
Py_DECREF(s);
s = NULL;
goto outtahere;
}
The error is that if _PyString_Resize runs out of memory, it automatically
decrefs the input string object s (which also deallocates it, since its
refcount must be 1 upon entry), and sets s to NULL. So if the "if"
branch ever triggers, it's an error to call Py_DECREF(s): s is already
NULL! A correct way to write the above is the simpler (and intended)
if (_PyString_Resize(&s, n) < 0)

Provisional fix for writefile() [SF bug # 541730].
The problem was that an exception can occur in the text.get() call or
in the write() call, when the text buffer contains non-ASCII
characters. This causes the previous contents of the file to be lost.
The provisional fix is to call str(self.text.get(...)) *before*
opening the file, so that if the exception occurs, we never open the
file.
Two orthogonal better solutions have to wait for policy decisions:
1. We could try to encode the data as Latin-1 or as UTF-8; but that
would require IDLE to grow a notion of file encoding which requires
more thought.
2. We could make backups before overwriting a file. This requires
more thought because it needs to be fast and cross-platform and
configurable.
