  * Update to 20161103 from the 2.7 branch.
    - Issue #21720: Improve exception message when the type of fromlist is
      unicode.  fromlist parameter of __import__() only accepts str in Python 2
      and this will help to identify the problem especially when the
      unicode_literals future import is used.
    - Issue #26906: Resolving special methods of uninitialized type now causes
      implicit initialization of the type instead of a fail.
    - Issue #18287: PyType_Ready() now checks that tp_name is not NULL.
    - Issue #24098: Fixed possible crash when AST is changed in process of
      compiling it.
    - Issue #28350: String constants with null character no longer interned.
    - Issue #27942: String constants now interned recursively in tuples and
      frozensets.
    - Issue #15578: Correctly incref the parent module while importing.
    - Issue #26307: The profile-opt build now applies PGO to the built-in
      modules.
    - Issue #26020: set literal evaluation order did not match documented
      behaviour.
    - Issue #28449: tarfile.open() with mode "r" or "r:" now tries to open a
      tar file with compression before trying to open it without compression.
      Otherwise it had 50% chance failed with ignore_zeros=True.
    - Issue #25464: Fixed HList.header_exists() in Tix module by adding
      a workaround to Tix library bug.
    - Issue #28488: shutil.make_archive() no longer adds entry "./" to ZIP
      archive.

      disabled.
    - Issue #26293: Fixed writing ZIP files that starts not from the start of
      the file.  Offsets in ZIP file now are relative to the start of the
      archive in conforming to the specification.
    - Fix possible integer overflows and crashes in the mmap module with
      unusual usage patterns.
    - Issue #27897: Fixed possible crash in
      sqlite3.Connection.create_collation() if pass invalid string-like object
      as a name.

    - Issue #28253: Fixed calendar functions for extreme months: 0001-01
      and 9999-12.
      Methods itermonthdays() and itermonthdays2() are reimplemented so
      that they don't call itermonthdates() which can cause datetime.date
      under/overflow.
    - Issue #27963: Fixed possible null pointer dereference in
      ctypes.set_conversion_mode().
    - Issue #28284: Strengthen resistance of ``_json.encode_basestring_ascii()``
      to integer overflow.
    - Issue #27611: Fixed support of default root window in the Tix module.
    - Issue #24363: When parsing HTTP header fields, if an invalid line is
      encountered, skip it and continue parsing.  Previously, no more header
      fields were parsed, which could lead to fields for HTTP framing like
      Content-Length and Transfer-Encoding being overlooked.
    - Issue #27599: Fixed buffer overrun in binascii.b2a_qp() and
      binascii.a2b_qp().

      pointers in the "ctypes" and "array" modules.

      default headers.  This makes the results of REST API requests more
      consistent and predictable especially when proxy servers are involved.
    - lib2to3.pgen3.driver.load_grammar() now creates a stable cache file
      between runs given the same Grammar.txt input regardless of the hash
      randomization setting.

      name fields in X.509 certs.

    - Issue #27983: Cause lack of llvm-profdata tool when using clang as
      required for PGO linking to be a configure time error rather than
      make time when --with-optimizations is enabled.  Also improve our
      ability to find the llvm-profdata tool on MacOS and some Linuxes.
