[PATCH v4 00/13] qapi: static typing conversion, pt5b

[John Snow]

Hello darkness my old friend; This is part five (b), and focuses on
QAPIDoc in parser.py.

GitLab: https://gitlab.com/jsnow/qemu/-/commits/python-qapi-cleanup-pt5b
CI: https://gitlab.com/jsnow/qemu/-/pipelines/380464863
    Note: intentional trailing whitespace in a QAPI schema test causes
    a warning on the `check-patch` CI test. Ignore it.

Requirements:
- Python 3.6+
- mypy >= 0.770
- pylint >= 2.6.0 (2.7.0+ when using Python 3.9+)

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

V4:

005/13:[0006] [FC] 'qapi/parser: remove FIXME comment from _append_body_line'
006/13:[down] 'qapi/parser: clarify _end_section() logic'
007/13:[0004] [FC] 'qapi/parser: Introduce NullSection'
010/13:[down] 'qapi/parser: Add FIXME for consolidating JSON-related types'

- Dropped formerly-patch-05, for now.
- Added a new FIXME comment to keep myself honest for pt5c O:-)
- (05) Adjusted a commend and the parser error message
- (06) Changed commit title for 06 ("simplify" => "clarify")
- (07) Adjust comment.
