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
Ref: https://github.com/pytest-dev/pytest/issues/4321#issuecomment-436951894
Hardens some of the not many tests affected by this:
1. `testing/test_session.py::test_rootdir_option_arg` displayed:
> root/test_rootdir_option_arg2/test_rootdir_option_arg.py
2. `test_cmdline_python_namespace_package` displayed "hello/" prefix for:
> hello/test_hello.py::test_hello
> hello/test_hello.py::test_other
`_collect_report_last_write` might be None, when `pytest_collection` was
not called before. Not sure if this indicates another problem, but it
can be reproduced with `testing/test_collection.py::TestCollector::()::test_getcustomfile_roundtrip`.

This is relevant when using runpytest in-process.
Fixes:

This removes the hack added in https://github.com/pytest-dev/pytest/pull/3802.
Adjusts test:
- it appears to not have been changed to 7 intentionally.
- removes XXX comment, likely not relevant anymore since 6dac7743.
Also renames `_path2confmods` to `_dirpath2confmods` for clarity (it is
expected to be a dirpath in `_importconftest`).
Uses an explicit maxsize, since it appears to be only relevant for a
short period [1].
Removes the lru_cache on _getconftest_pathlist, which makes no
difference when caching _getconftestmodules, at least with the
performance test of 100x10 files (#4237).
