          [PATCH v2 00/38] qapi: static typing conversion, pt1

Hi, this series adds static type hints to the QAPI module.
This is part two!

Part 2: https://gitlab.com/jsnow/qemu/-/tree/python-qapi-cleanup-pt2
Everything: https://gitlab.com/jsnow/qemu/-/tree/python-qapi-cleanup-pt6

- Requires Python 3.6+
- Requires mypy 0.770 or newer (for type analysis only)
- Requires pylint 2.6.0 or newer (for lint checking only)

This part of the series focuses on just expr.py.

Type hints are added in patches that add *only* type hints and change no
other behavior. Any necessary changes to behavior to accommodate typing
are split out into their own tiny patches.

Every commit should pass with:
 - flake8 qapi/
 - pylint --rcfile=qapi/pylintrc qapi/
 - mypy --config-file=qapi/mypy.ini qapi/
