Christian Heimes a37d4c693a Removed PyInt_GetMax and sys.maxint
I replaced sys.maxint with sys.maxsize in Lib/*.py. Does anybody see a problem with the change on Win 64bit platforms? Win 64's long is just 32bit but the sys.maxsize is now 2**63-1 on every 64bit platform.
Also added docs for sys.maxsize.

Guido van Rossum 98297ee781 Merging the py3k-pep3137 branch back into the py3k branch.
No detailed change log; just check out the change log for the py3k-pep3137
branch.  The most obvious changes:

  - str8 renamed to bytes (PyString at the C level);
  - bytes renamed to buffer (PyBytes at the C level);
  - PyString and PyUnicode are no longer compatible.

I.e. we now have an immutable bytes type and a mutable bytes type.

The behavior of PyString was modified quite a bit, to make it more
bytes-like.  Some changes are still on the to-do list.

other code generating print statements in strings is the minor category.

  [Apply length-checking.diff from bug #1599254]

  Add length checking to single-file mailbox formats: before doing a
  flush() on a mailbox, seek to the end and verify its length is
  unchanged, raising ExternalClashError if the file's length has
  changed.

  This fix avoids potential data loss if some other process appends to
  the mailbox file after the table of contents has been generated;
  instead of overwriting the modified file, you'll get the exception.

  I also noticed that the self._lookup() call in self.flush() wasn't
  necessary (everything that sets self._pending to True also calls
  self.lookup()), and replaced it by an assertion.

  2.5 backport candidate.
