Inspired by SF patch #408597 (Walter Dörwald): quopri, soft line
breaks and CRLF.  (I changed (" ", "\t", "\r") into " \t\r".)

This is SF patch # #409044, by Internet Discovery: "Update tcl/tk/tix
versions".

# 409287, ssl fix when using _socketobject, by Robin Dunn.

I took the opportunity to improve the way it deals with reload(socket)
for the socket function as well.

cmd.py uses raw_input(); eats SIGCLD:

  I discovered a rather nasty side effect of the standard cmd.py
  library today. If it's sitting inside raw_input(), any SIGCLDs that
  get sent to your application get silently eaten and ignored. I'm
  assuming that this is something that readline is thoughtfully doing
  for me.

  This patch adds an instance attr that allows the user to select to
  not use raw_input(), but instead use sys.stdin.readline()

[Changed slightly to catch EOFError only for raw_input().]

must now initialize the extra field used by the weak-ref machinery to
NULL themselves, to avoid having to require PyObject_INIT() to check
if the type supports weak references and do it there.  This causes less
work to be done for all objects (the type object does not need to be
consulted to check for the Py_TPFLAGS_HAVE_WEAKREFS bit).

tracked as soon as it is clear; this can decrease the number of roots for
the cycle detector sooner rather than later in applications which hold on
to weak references beyond the time of the invalidation.

the new.instance() function.

If a module has a future statement enabling nested scopes, they are
also enable for the exec statement and the functions compile() and
execfile() if they occur in the module.

If Python is run with the -i option, which enters interactive mode
after executing a script, and the script it runs enables nested
scopes, they are also enabled in interactive mode.

XXX The use of -i with -c "from __future__ import nested_scopes" is
not supported.  What's the point?

To support these changes, many function variants have been added to
pythonrun.c.  All the variants names end with Flags and they take an
extra PyCompilerFlags * argument.  It is possible that this complexity
will be eliminated in a future version of the interpreter in which
nested scopes are not optional.

Add PyEval_GetNestedScopes() which returns a non-zero value if the
code for the current interpreter frame has CO_NESTED defined.
