#544265, Remove warnings for passing const to free()

1.39:
Fix SF bug 610610 (reported by Martijn Pieters, diagnosed by Neal Norwitz).

The switch in Exception__str__ didn't clear the error if
PySequence_Size() raised an exception.  Added a case -1 which clears
the error and falls through to the default case.

1.40:
Two more cases of switch(PySequence_Size()) without checking for case -1.
(Same problem as last checkin for SF bug 610610)
Need to clear the error and proceed.

unicodeobject.c 2.169
stringobject.c 2.189

Fix warnings on 64-bit platforms about casts from pointers to ints.
Two of these were real bugs.

Insert an overflow check when the sequence repetition count is outside
the range of ints.  The old code would pass random truncated bits to
sq_repeat() on a 64-bit machine.

1.51:
Bug #556025: list(xrange(1e9)) --> seg fault

Close the bug report again -- this time for Cygwin due to a newlib bug.
See the following for the details:

	http://sources.redhat.com/ml/newlib/2002/msg00369.html

Note that this commit is only a documentation (i.e., comment) change.

1.54:
The list(xrange(sys.maxint / 4)) test blew up on 64-bit platforms.
Because ob_size is a 32-bit int but sys.maxint is LONG_MAX which is a
64-bit value, there's no way to make this test succeed on a 64-bit
platform.  So just skip it when sys.maxint isn't 0x7fffffff.

(Most of) SF patch 601369 (Christos Georgiou): obmalloc,structmodule:
64bit, big endian (issue 2 only).

This adds a bunch of memcpy calls via a temporary variable to avoid
alignment errors.  That's needed for some platforms.

1.56:
Apply diff3.txt from SF patch http://www.python.org/sf/536241

If a str or unicode method returns the original object,
make sure that for str and unicode subclasses the original
will not be returned.

This should prevent SF bug http://www.python.org/sf/460020
from reappearing.

1.68:
Fix SF bug 599128, submitted by Inyeol Lee: .replace() would do the
wrong thing for a unicode subclass when there were zero string
replacements.  The example given in the SF bug report was only one way
to trigger this; replacing a string of length >= 2 that's not found is
another.  The code would actually write outside allocated memory if
replacement string was longer than the search string.

Add a bunch of sys.stdout.flush() calls that will hopefully improve
the usability of the output of the Xenofarm builds.

SF bug 594996:  OverflowError in random.randrange
Loosened the acceptable 'start' and 'stop' arguments so that any
Python (bounded) ints can be used.  So, e.g., randrange(-sys.maxint-1,
sys.maxint) no longer blows up.

random.gauss() uses a piece of hidden state used by nothing else,
and the .seed() and .whseed() methods failed to reset it.  In other
words, setting the seed didn't completely determine the sequence of
results produced by random.gauss().  It does now.  Programs repeatedly
mixing calls to a seed method with calls to gauss() may see different
results now.

Bugfix candidate (random.gauss() has always been broken in this way),
despite that it may change results.

The test for re.engine was misfiring because re.engine is no longer
defined and the default was "pre" instead of "sre".  Give up on 1.5.2
compatibility, hardcode the sre solution.  However, this XXX comment
still applies, AFAIK:
        # XXX This code depends on internals of the regular expression
        # engine!  There's no standard API to do a substitution when you
        # have already found the match.  One should be added.

Convert characters from the locale's encoding on output.
Reject characters outside the locale's encoding on input.

Address SF bug #577530: del __builtins__ breaks out of rexec

Using the suggestion there: add_module() forces __builtin__ back; this
fixes r_exec, r_eval, r_execfile.

This does not mean that rexec is now considered safe!  But for those
willing to take the risk, it's safer than before.  (Note that a safety
analysis of the code module would be wise if you plan to use the
interactive console for real -- I've only ever used it to play with
restricted mode.)

Raise ValueError if user passes a size to mmap which is larger

Also need Tim's fix in test_mmap.py, 1.22 which flushes the file
before mmap'ing it.
