Might be worth handling (converting it to a list for example), but it
was documented to be a list to begin with when removing support for
strings (a7e401656).
Remove `_tmp_path_factory` and `_tmpdirhandler` from the config object.
- `_tmpdirhandler` has been deprecated since 2.8.0 (0f52856f9), when
`tmpdir_factory` has been added.
- `_tmp_path_factory` should have probably never been added there in the
first place, but maybe just used the same pattern (16e2737da).
This better reflects the inheritance / smartness with regard to raw or
encoded.

Mypy currently is unable to handle assigning attributes on function:
https://github.com/python/mypy/issues/2087.
pytest uses this for the outcome exceptions -- `pytest.fail.Exception`,
`pytest.exit.Exception` etc, and this is the canonical name by which they
are referred.
Initially we started working around this with type: ignores, and later
by switching e.g. `pytest.fail.Exception` with the direct exception
`Failed`. But this causes a lot of churn and is not as nice. And I also
found that some code relies on it, in skipping.py:
def pytest_configure(config):
if config.option.runxfail:
# yay a hack
import pytest
old = pytest.xfail
config._cleanup.append(lambda: setattr(pytest, "xfail", old))
def nop(*args, **kwargs):
pass
nop.Exception = xfail.Exception
setattr(pytest, "xfail", nop)
...
So it seems better to support it. Use a hack to make it work. The rest
of the commit rolls back all of the workarounds we added up to now.
`pytest.raises.Exception` also exists, but it's not used much so I kept
it as-is for now.
Hopefully in the future mypy supports this and this ugliness can be
removed.
Allows for filtering of PytestCacheWarning.
Using `_issue_warning_captured` is not necessary here, and was probably
only used because the cacheprovider misses warnings during
`pytest_sessionfinish`, which is also fixed here.
I think the usage of `_issue_warning_captured` can be removed/reduced
further, but also that this is good enough for now.

* Turn ReprTraceback into attrs class
* Use attr.asdict with serialize_repr_{crash,traceback}
* Turn ReprFileLocation into attrs class, convert py.path.local
