Added two new attributes rootpath <_pytest.config.Config.rootpath>
and inipath <_pytest.config.Config.inipath>
to Config <_pytest.config.Config>
. These attributes are pathlib.Path
versions of the existing rootdir <_pytest.config.Config.rootdir>
and inifile <_pytest.config.Config.inifile>
attributes, and should be preferred over them when possible.
