Previously, the expressions given to the `-m` and `-k` options were
evaluated with `eval`. This causes a few issues:
- Python keywords cannot be used.
- Constants like numbers, None, True, False are not handled correctly.
- Various syntax like numeric operators and `X if Y else Z` is supported
unintentionally.
- `eval()` is somewhat dangerous for arbitrary input.
- Can fail in many ways so requires `except Exception`.
The format we want to support is quite simple, so change to a custom
parser. This fixes the issues above, and gives us full control of the
format, so can be documented comprehensively and even be extended in the
future if we wish.
* tests: fix TypeError with test_mark_closest
It fails when trying to run it actually:
> TypeError: test_has_inherited() takes 0 positional arguments but 1 was given
* Fix testing/test_collection.py::TestCollector::test_getparent
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`.
It is a little too obscure IMO, but the reason I want to drop it is that
type checking has no hope of understanding such dynamic constructs.
The warning argument wasn't used.

Related to #5275
It doesn't seem to add much value (why would one execute tests
based on that marker?), plus using the docstring for that
encourages one to write a more descriptive message about the test
This was documented before, but never enforced. Passing non-strings could
have strange side-effects and enforcing a string simplifies other
implementation.
To keep existing tests which emit RemovedInPytest4Warnings running, decided
to go with a command line option because:
* Is harder to integrate an ini option with tests which already use an ini file
* It also marks tests which need to be removed/updated in 4.1, when
RemovedInPytest4Warning and related functionality are removed.
Fix#3737
