python36: updated to 3.6.6

Version 3.6.6:

Core and Builtins
* Fix asynchronous generators to handle GeneratorExit in athrow() correctly
* Fixed reset of the SIGINT handler to SIG_DFL on interpreter shutdown even when \ 
there was a custom handler set previously.
* Fixed a leak when the garbage collector fails to add an object with the \ 
__del__ method or referenced by it into the gc.garbage list. PyGC_Collect() can \ 
now be called when an exception is set and preserves it.
* Fix signed/unsigned comparison warning in pyhash.c.
* Fix a leak in set_symmetric_difference().
* Fix unaligned accesses in siphash24().
* Fix potential memory leak in normalizestring().
* Improved error messages in ‘async with’ when __aenter__() or __aexit__() \ 
return non-awaitable object.
* Fix ma_version_tag in dict implementation is uninitialized when copying from \ 
key-sharing dict.
* Fixed jumping when the function contains an async for loop.
* Fix an unnecessary ifdef in the include of VersionHelpers.h in socketmodule on \ 
Windows.
* Fix a crash in ctypes.cast() in case the type argument is a ctypes structured \ 
data type.

Library
* Prevent site.main() exception if PYTHONSTARTUP is set.
* Datetime instance d with non-None tzinfo, but with d.tzinfo.utcoffset(d) \ 
returning None is now treated as naive by the astimezone() method.
* Avoid race condition with debug logging
* The concatenation (+) and repetition (*) sequence operations now raise \ 
TypeError instead of SystemError when performed on mmap.mmap objects.
* Fix gather to propagate cancellation of itself even with return_exceptions.
* Fix a race condition in SSLProtocol.connection_made() of asyncio.sslproto: \ 
start immediately the handshake instead of using call_soon(). Previously, \ 
data_received() could be called before the handshake started, causing the \ 
handshake to hang or fail.
* Fixed bug where calling write_eof() on a _SelectorSocketTransport after it’s \ 
already closed raises AttributeError.
* Fix Task.__repr__ crash with Cython’s bogus coroutines
* Fix RuntimeError after closing loop that used run_in_executor
* Use a better regex when breaking usage into wrappable parts. Avoids bogus \ 
assertion errors from custom metavar strings.
* Fixed a bug in the Python implementation of the JSON decoder that prevented \ 
the cache of parsed strings from clearing after finishing the decoding. Based on \ 
patch by c-fos.
* tempfile._candidate_tempdir_list should consider common TEMP locations
* Prevent uuid.get_node from using a DUID instead of a MAC on Windows.
* Fix race condition with ReadTransport.resume_reading in Windows proactor event \ 
loop.
* Minor fixes in typing module: add annotations to NamedTuple.__new__, pass \ 
*args and **kwds in Generic.__new__.
* Updated alias mapping with glibc 2.27 supported locales.
* Fix trailing quotation marks getting deleted when looking up byte/string \ 
literals on pydoc.
* Update error message when constructing invalid inspect.Parameters
* Fixed crash in the get() method of the dbm.ndbm database object when it is \ 
called with a single argument.
* Fix multiprocessing regression on newer glibcs
* Fix quoting of the Comment attribute of http.cookies.SimpleCookie.
* Upgrade bundled version of pip to 10.0.1.
* Fixed a crash in the parser module when converting an ST object to a tree of \ 
tuples or lists with line_info=False and col_info=True.
* Fix FD leak in _SelectorSocketTransport
* Fix display of <module> call in the html produced by cgitb.html().
* random.Random.choice() now raises IndexError for empty sequences consistently \ 
even when called from subclasses without a getrandbits() implementation.
* Update difflib.mdiff() for PEP 479. Convert an uncaught StopIteration in a \ 
generator into a return-statement.
* End framing at the end of C implementation of pickle.Pickler.dump().
* The urllib.robotparser’s __str__ representation now includes wildcard \ 
entries and the “Crawl-delay” and “Request-rate” fields.
* Allow ttk.Treeview.insert to insert iid that has a false boolean value. Note \ 
iid=0 and iid=False would be same.
* The ssl module now compiles with LibreSSL 2.7.1.
* Release the GIL during fstat() calls, avoiding hang of all threads when \ 
calling mmap.mmap(), os.urandom(), and random.seed().
* Fix a regression in ipaddress that result of hosts() is empty when the network \ 
is constructed by a tuple containing an integer mask and only 1 bit left for \ 
addresses.
* Fix wrong redirection of a low descriptor (0 or 1) to stderr in subprocess if \ 
another low descriptor is closed.
* Fix output of cover files for trace module command-line tool. Previously \ 
emitted cover files only when --missing option was used.
* If nested log adapters are used, the inner process() methods are no longer omitted.
* Support arrays >=2GiB in ctypes.
* pydoc: the stop() method of the private ServerThread class now waits until \ 
DocServer.serve_until_quit() completes and then explicitly sets its docserver \ 
attribute to None to break a reference cycle.
