crecord: null out the curses attribute with `None` on failure to import Pytype got really confused that this could be `Union[module, bool]`, and spewed about tons of attributes that are not available on `bool`. Differential Revision: https://phab.mercurial-scm.org/D10210

typing: disable import error warnings that are already handled I'm assuming that the cffi ones are handled somewhere, but the others definitely are. Differential Revision: https://phab.mercurial-scm.org/D10207

typing: disable a few errors when accessing Windows specific attributes This is already guarded with conditionals. The entire win32 module is conditionally loaded.

wsgicgi: switch the default PATH_INFO back to str It looks like everything here is meant to be str, and regressed in 687b865b95ad. Pytype didn't flag this, but is really confused about the range of possible types for the dictionary values, and flagged missing `lower()` on various types in this area.
