John Snow Sept. 22, 2020, 9 p.m. UTC 
Fix two very minor issues, and then establish a mypy type-checking
baseline.

Like pylint, this should be run from the folder above:

 > mypy --config-file=qapi/mypy.ini qapi/

Like with pylint, let's at least document the version of mypy used.
For example, with 0.740, this fails.  With 0.782, it passes.

- Cleber.
