Check_untyped_defs in mypy with clean output for acme (#5874)

* check_untyped_defs in mypy with clean output for acme

* test entire acme module

* Add typing as a dependency because it's only in the stdlib for 3.5+

* Add str_utils, modified for python2.7 compatibility

* make mypy happy in acme

* typing is needed in prod

* we actually only need typing in acme so far

* add tests and more docs for str_utils

* pragma no cover

* add magic_typing

* s/from typing/from magic_typing/g

* move typing to dev_extras

* correctly set up imports

* remove str_utils

* only type: ignore for OpenSSL.SSL, not crypto

* Since we only run mypy with python3 anyway and we're fine importing it when it's not actually there, there's no actual need for typing to be present as a dependency

* comment magic_typing.py

* disable wildcard-import im magic_typing

* disable pylint errors

* add magic_typing_test

* make magic_typing tests work alongside other tests

* make sure temp_typing is set

* add typing as a dev dependency for python3.4

* run mypy with python3.4 on travis to get a little more testing with different environments

* don't stick typing into sys.modules

* reorder imports
