Missing stubs in Python 3.6 standard library

[JelleZijlstra]

The following modules in the Python 3.6 standard library do not have stubs:

• _bootlocale
• _collections_abc
• _compat_pickle
• _osx_support
• _pydecimal
• _pyio
• _sitebuiltins
• _strptime
• _sysconfigdata_m_darwin_darwin
• _threading_local
• _weakrefset
• aifc
• bdb
• binhex
• cgitb
• chunk
• cmd
• codeop
• compileall
• copyreg
• crypt
• dummy_threading
• formatter
• genericpath
• imaplib
• imghdr
• lzma
• macpath
• macurl2path
• mailbox
• mailcap
• modulefinder
• netrc
• nntplib
• ntpath
• nturl2path
• optparse
• pickletools
• poplib
• pty
• pydoc
• quopri
• reprlib
• sched
• smtpd
• sndhdr
• sre_compile
• sre_constants
• sre_parse
• statistics
• stringprep
• sunau
• symbol
• symtable
• tabnanny
• telnetlib
• this
• timeit
• trace
• tracemalloc
• tty
• uu
• wave
• xdrlib
• zipapp

Found this with https://github.com/JelleZijlstra/stubcheck. Some of these are private or aren't intended to be imported.

Added statistics in #1021.

These modules seem to be internal to CPython and thus not a priority:

• Modules starting with _.
• genericpath (used through os.path)
• sre_compile
• sre_constants
• sre_parse

[JelleZijlstra]

Just realized this is missing modules implemented in C.

Also https://docs.python.org/3/library/internet.html is missing,
in particular xmlrpc

This list is a good idea. I'm going to do something similar for Python 2
