* Add flags to pass on --warn-unused-ignores and --no-implicit-optional to mypy
* Make implicit Optional explicit in arg types (2and3 part)
* Convert {stdlib,third_party}/2 to explicit Optional
Both mypy and pytype only use the major and minor version in type checking. Using
checks like "sys.version_info >= (3, 4, 4)" won't actually work properly for
people type checking their code using version 3.4, because (3, 4) >= (3, 4, 4) will
always be false (at least in mypy's approach; not sure if pytype is different).
* Stub: asyncore.pyi
I can't really test this stub since I don't use this module. I believe it's not far from the real thing.
It's based on the source code and not on the documentation.

* Option ->Optional
* add hint to count, remove addr
* make read/write explicit functions
* add synchat.pyi, move to 2and3
* change sys.version_info test
* try reversing the syntax
