A precise style guide and a package-wide overhaul is forthcoming pending
further discussion and consensus. For now, merely avoid obvious errors
that cause Sphinx documentation build problems, using a style loosely
based on PEP 257 and Sphinx Autodoc. It is chosen for interoperability
with our existing Sphinx framework, and because it has loose recognition
in the Pycharm IDE.

As part of delinting and adding type hints to the QAPI generator, it's
helpful for the entrypoint to be part of the package, only leaving a
very tiny entrypoint shim outside of the package.

John Snow, Eduardo Habkost, Cleber Rosa
From: John Snow <jsnow@redhat.com>
All of the QAPI include statements are changed to be package-aware, as
explicit relative imports.
A quirk of Python packages is that the name of the package exists only
*outside* of the package. This means that to a module inside of the qapi
folder, there is inherently no such thing as the "qapi" package. The
reason these imports work is because the "qapi" package exists in the
context of the caller -- the execution shim, where sys.path includes a
directory that has a 'qapi' folder in it.
When we write "from qapi import sibling", we are NOT referencing the folder
'qapi', but rather "any package named qapi in sys.path". If you should
so happen to have a 'qapi' package in your path, it will use *that*
package.
When we write "from .sibling import foo", we always reference explicitly
our sibling module; guaranteeing consistency in *where* we are importing
these modules from.
This can be useful when working with virtual environments and packages
in development mode. In development mode, a package is installed as a
series of symlinks that forwards to your same source files. The problem
arises because code quality checkers will follow "import qapi.x" to the
"installed" version instead of the sibling file and -- even though they
are the same file -- they have different module paths, and this causes
cyclic import problems, false positive type mismatch errors, and more.
It can also be useful when dealing with hierarchical packages, e.g. if
we allow qemu.core.qmp, qemu.qapi.parser, etc.

Wildcard includes become hard to manage when refactoring and dealing
with circular dependencies with strictly typed mypy.
flake8 also flags each one as a warning, as it is not smart enough to
know which names exist in the imported file.
Remove them and include things explicitly by name instead.

From: John Snow <jsnow@redhat.com>
While we're mucking around with imports, we might as well formalize the
style we use. Let's use isort to do it for us.
lines_after_imports=2: Use two lines after imports, to match PEP8's
desire to have "two lines before and after" class definitions, which are
likely to start immediately after imports.
force_sort_within_sections: Intermingles "from x" and "import x" style
statements, such that sorting is always performed strictly on the module
name itself.
force_grid_wrap=4: Four or more imports from a single module will force
the one-per-line style that's more git-friendly. This will generally
happen for 'typing' imports.
multi_line_output=3: Uses the one-per-line indented style for long
imports.
include_trailing_comma: Adds a comma to the last import in a group,
which makes git conflicts nicer to deal with, generally.
line_length: 72 is chosen to match PEP8's "docstrings and comments" line
length limit. If you have a single line import that exceeds 72
characters, your names are too long!

Petty style guide fixes and line length enforcement. Not a big win, not
a big loss, but flake8 passes 100% on the qapi module, which gives us an
easy baseline to enforce hereafter.
A note on the flake8 exception: flake8 will warn on *any* bare except,
but pylint's is context-aware and will suppress the warning if you
re-raise the exception.

Using `pylint --generate-rcfile > pylintrc`, generate a skeleton
pylintrc file. Sections that are not presently relevant (by the end of
this series) are removed leaving just the empty section as a search
engine / documentation hint to future authors.
I am targeting pylint 2.6.0. In the future (and hopefully before 5.2 is
released), I aim to have gitlab CI running the specific targeted
versions of pylint, mypy, flake8, etc in a job.
2.5.x will work if you additionally pass --disable=bad-whitespace.
This warning was removed from 2.6.x, for lack of consistent support.
Right now, quite a few modules are ignored as they are known to fail as
of this commit. modules will be removed from the known-bad list
throughout this and following series as they are repaired.
Note: Normally, pylintrc would go in the folder above the module, but as
that folder is shared by many things, it is going inside the module
folder (for now). Due to a bug in pylint 2.5+, pylint does not
correctly recognize when it is being run from "inside" a package, and
must be run *outside* of the package.
Therefore, to run it, you must:
> pylint scripts/qapi/ --rcfile=scripts/qapi/pylintrc

Code style tools really dislike the use of global keywords, because it
generally involves re-binding the name at runtime which can have strange
effects depending on when and how that global name is referenced in
other modules.
Make a little indent level manager instead.

At this point, that just means using a consistent strategy for constant names.
constants get UPPER_CASE and names not used externally get a leading underscore.
As a preference, while renaming constants to be UPPERCASE, move them to
the head of the file. Generally, it's nice to be able to audit the code
that runs on import in one central place.

Annotations do not change runtime behavior.
This commit *only* adds annotations.
Note that build_params() cannot be fully annotated due to import
dependency issues. The commit after next will take care of it.

From: John Snow <jsnow@redhat.com>
As docstrings, they'll show up in documentation and IDE help.
The docstring style being targeted is the Sphinx documentation
style. Sphinx uses an extension of ReST with "domains". We use the
(implicit) Python domain, which supports a number of custom "info
fields". Those info fields are documented here:
https://www.sphinx-doc.org/en/master/usage/restructuredtext/domains.html#info-field-lists
Primarily, we use `:param X: descr`, `:return[s]: descr`, and `:raise[s]
Z: when`. Everything else is the Sphinx dialect of ReST.
(No, nothing checks or enforces this style that I am aware of. Sphinx
either chokes or succeeds, but does not enforce a standard of what is
otherwise inside the docstring. Pycharm does highlight when your param
fields are not aligned with the actual fields present. It does not
highlight missing return or exception statements. There is no existing
style guide I am aware of that covers a standard for a minimally
acceptable docstring. I am debating writing one.)

Including it in common.py creates a circular import dependency; schema
relies on common, but common.build_params requires a type annotation
from schema. To type this properly, it needs to be moved outside the
cycle.

Fix a minor typing issue, 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/
This is designed and tested for mypy 0.770 or greater.

Annotations do not change runtime behavior.
This commit *only* adds annotations.
A note on typing of __init__: mypy requires init functions with no
parameters to document a return type of None to be considered fully
typed. In the case when there are input parameters, None may be omitted.
Since __init__ may never return any value, it is preferred to omit the
return annotation whenever possible.

Make the file handling here just a tiny bit more idiomatic.
(I realize this is heavily subjective.)
Use exist_ok=True for os.makedirs and remove the exception,
use fdopen() to wrap the file descriptor in a File-like object,
and use a context manager for managing the file pointer.

'fp' and 'fd' are self-evident in context, add them to the list of OK
names.
_top and _bottom also need to stay standard methods because some users
override the method and need to use `self`. Tell pylint to shush.

The "GCC check-tcg (user)" is 6 min slower since this pull request,
making Travis-CI fails:
https://travis-ci.org/github/qemu/qemu/builds/734773760
https://travis-ci.org/github/qemu/qemu/builds/734983001
Any remote idea what could be the reason?

limited to whitespace.
