Applied patch 1124861.3.patch to solve bug #1124861: Automatically create pipes on Windows, if GetStdHandle fails. Backport from rev 53646.

the master should close the slave fd.

Added a test to test_pty.py that reads from the master_fd after doing
a pty.fork(); without the fix it hangs forever instead of raising an
exception.  (<crossing fingers for the buildbots>)

  Fix for #1643874: When calling SysAllocString, create a PyCObject
  which will eventually call SysFreeString to free the BSTR resource.

segfault the interpreter during weakref clean up.  Now any new weakrefs created
after __del__ is run are removed silently.

Fixes bug #1377858 and the weakref_in_del crasher for new-style classes.
Classic classes are still affected.

frame's thread state. Fixes #1579370.

SF patch #1630975: Fix crash when replacing sys.stdout in sitecustomize

When running the interpreter in an environment that would cause it to set
stdout/stderr/stdin's encoding, having a sitecustomize that would replace
them with something other than PyFile objects would crash the interpreter.
Fix it by simply ignoring the encoding-setting for non-files.

This could do with a test, but I can think of no maintainable and portable
way to test this bug, short of adding a sitecustomize.py to the buildsystem
and have it always run with it (hmmm....)
