This option checks even functions which are not annotated. It's a good
step to ensure that existing type annotation are correct.
In a Pareto fashion, the last few holdouts are always the ugliest,
beware.
_pytest.timing is an indirection to 'time' functions, which pytest production
code should use instead of 'time' directly.
'mock_timing' is a new fixture which then mocks those functions, allowing us
to write time-reliable tests which run instantly and are not flaky.
This was triggered by recent flaky junitxml tests on Windows related to timing
issues.
When using `(i)var` in the class docstring it would link `duration` to
`_pytest.runner.TestReport.duration`.
This moves the docstrings to the attributes properly.
ExitCode is used in several internal modules and hooks and so with type
annotations added, needs to be imported a lot.
_pytest.main, being the entry point, generally sits at the top of the
import tree.
So, it's not great to have ExitCode defined in _pytest.main, because it
will cause a lot of import cycles once type annotations are added (in
fact there is already one, which this change removes).
Move it to _pytest.config instead.
_pytest.main still imports ExitCode, so importing from there still
works, although external users should really be importing from `pytest`.
Without restoring the cwd, successive tests might fail to parse the
config (via `_pytest.config._prepareconfig()`, for when `--lsof` is
used).
And it is good practice to restore the cwd in any case anyway.
This allows for e.g. Jedi to infer types (it checks the name).
It was only used to support Python 3.5.0/3.5.1, where this is is not
available in the `typing` module.

Uses `TYPE_CHECKING = False` in `_pytest.outcomes` to avoid having to
work around circular import.
This fixes some type: ignores due to typeshed update.
Newer mypy seem to ignore unannotated functions better, so add a few
minor annotations so that existing correct type:ignores make sense.
Sets `PY_COLORS=0` in the environment by default, which is used by pylib.
