python36: updated to 3.6.5

Python 3.6.5:

Security
* Minimal fix to prevent buffer overrun in os.symlink on Windows
* Regexes in difflib and poplib were vulnerable to catastrophic backtracking. \ 
These regexes formed potential DOS vectors (REDOS). They have been refactored. \ 
This resolves CVE-2018-1060 and CVE-2018-1061.

Core and Builtins
* Fixed jumping out of “with” block by setting f_lineno.
* Prevent jumps from ‘return’ and ‘exception’ trace events.
* Update Valgrind suppression list to account for the rename of \ 
Py_ADDRESS_IN_RANG to address_in_range.
* Pdb and other debuggers dependent on bdb.py will correctly step over (next \ 
command) native coroutines.
* Improve suggestion when the Python 2 form of print statement is either present \ 
on the same line as the header of a compound statement or else terminated by a \ 
semi-colon instead of a newline.
* Fix possible crashing in builtin Unicode decoders caused by write out-of- \ 
bound errors when using customized decode error handlers.
* Improved frozenset() hash to create more distinct hash values when faced with \ 
datasets containing many similar values.
* The __debug__ constant is now optimized out at compile time. This fixes also \ 
bpo-22091.
* sys.flags.hash_randomization is now properly set to 0 when hash randomization \ 
is turned off by PYTHONHASHSEED=0.
* The optimizer is now protected from spending much time doing complex \ 
calculations and consuming much memory for creating large constants in constant \ 
folding.
* repr() on a dict containing its own values() or items() no longer raises \ 
RecursionError; OrderedDict similarly. Instead, use ..., as for other recursive \ 
structures.
* Leading whitespace is now correctly ignored when generating suggestions for \ 
converting Py2 print statements to Py3 builtin print function calls.
* The repr of deeply nested dict now raises a RecursionError instead of crashing \ 
due to a stack overflow.

Library
* lib2to3 now properly supports trailing commas after *args and **kwargs in \ 
function signatures.
* Avoid failing in multiprocessing.Process if the standard streams are closed or \ 
None at exit.
* Skip sending/receiving data after SSL transport closing.
* Fix ctypes pass-by-value for structs on 64-bit Cygwin/MinGW.
* Fix inspect.signature() for single-parameter partialmethods.
* Expose several missing constants in zlib and fix corresponding documentation.
* Fixed tarfile.itn handling of out-of-bounds float values.
* The ssl module now detects missing NPN support in LibreSSL.
* dbm.open() now encodes filename with the filesystem encoding rather than \ 
default encoding.
* In os.dup2, don’t check every call whether the dup3 syscall exists or not.
* Rewrite confusing message from setup.py upload from “No dist file created in \ 
earlier command” to the more helpful “Must create and upload files in one \ 
command”.
* In tkinter, after_cancel(None) now raises a ValueError instead of canceling \ 
the first scheduled function.
* Make sure sys.argv remains as a list when running trace.
* Fixed asyncio.Condition issue which silently ignored cancellation after \ 
notifying and cancelling a conditional lock.
* Fixed refleaks of __init__() methods in various modules. (Contributed by Oren \ 
Milman)
* Fixed guessing quote and delimiter in csv.Sniffer.sniff() when only the last \ 
field is quoted.
* socket: Remove TCP_FASTOPEN, TCP_KEEPCNT flags on older version Windows during \ 
run-time.
* Fix a rare but potential pre-exec child process deadlock in subprocess on \ 
POSIX systems when marking file descriptors inheritable on exec in the child \ 
process. This bug appears to have been introduced in 3.4.
* The ctypes module used to depend on indirect linking for dlopen. The shared \ 
extension is now explicitly linked against libdl on platforms with dl.
* Fixed asyncio.Lock() safety issue which allowed acquiring and locking the same \ 
lock multiple times, without it being free.
* Do not include name field in SMTP envelope from address.
* Fix email address header parsing error when the username is an empty quoted string.
* distutils’ upload command no longer corrupts tar files ending with a CR \ 
byte, and no longer tries to convert CR to CRLF in any of the upload text \ 
fields.
* uuid.uuid1 no longer raises an exception if a 64-bit hardware address is \ 
encountered.
* Fix the error handling in Aifc_read.initfp() when the SSND chunk is not found.
* On FreeBSD and Solaris, os.strerror() now always decode the byte string from \ 
the current locale encoding, rather than using ASCII/surrogateescape in some \ 
cases.
* The nis module is now compatible with new libnsl and headers location.
* Improve ABCMeta._dump_registry() output readability
* glibc has removed Sun RPC. Use replacement libtirpc headers and library in nis \ 
module.
* Ensure that truncate() preserves the file position (as reported by tell()) \ 
after writes longer than the buffer size.
* Don’t unsubscribe signals in asyncio UNIX event loop on interpreter shutdown.
* The SSL module no longer sends IP addresses in SNI TLS extension on platforms \ 
with OpenSSL 1.0.2+ or inet_pton.
* urllib.parse.urlsplit() does not convert zone-id (scope) to lower case for \ 
scoped IPv6 addresses in hostnames now.
* Fix bdist_wininst of distutils for CRT v142: it binary compatible with CRT v140.
* A single empty field is now always quoted when written into a CSV file. This \ 
allows to distinguish an empty row from a row consisting of a single empty \ 
field.
* Raise NotImplementedError instead of SystemError on platforms where chmod(..., \ 
follow_symlinks=False) is not supported.
* The getnode() ip getter now uses ‘ip link’ instead of ‘ip link list’.
* Ensure TCP_NODELAY is set on Linux. Tests by Victor Stinner.
* The locale.localeconv() function now sets temporarily the LC_CTYPE locale to \ 
the LC_NUMERIC locale to decode decimal_point and thousands_sep byte strings if \ 
they are non-ASCII or longer than 1 byte, and the LC_NUMERIC locale is different \ 
than the LC_CTYPE locale. This temporary change affects other threads.
Same change for the str.format() method when formatting a number (int, float, \ 
float and subclasses) with the n type (ex: '{:n}'.format(1234)).
* Importing native path module (posixpath, ntpath) now works even if the os \ 
module still is not imported.
