Fixes a pytest-xdist regression after
762bb61562 (not yet released).
pytest-xdist patches sys.stderr with an object which doesn't have
`encoding`. Strictly speaking, this should be fixed there (or more
precisely, in execnet), but it will drop support for older versions
which don't want.
But in any case, the fix turns out to simplify the code, using FD
support added in Python 3.5, so it's good anyway!

* faulthandler: fix an EncodingWarning
* _py/path: tiny change to `ensure` to silence EncodingWarning
We're not supposed to diverge here, but make this change to fix an
unavoidable EncodingWarning that is otherwise raised in pytest's test
suite. The behavior should be exactly the same besides the warning,
hopefully that won't cause confusion.
It seems the code that would not install pytest's faulthandler support
if it was already enabled is not really needed at all, and even detrimental
when using `python -X dev -m pytest` to run Python in "dev" mode.
Also simplified the plugin by removing the hook class, now the hooks
will always be active so there's no need to delay the hook definitions anymore.
Fix#8258
The Twisted Logger will return an invalid file descriptor since it is
not backed by an FD. So, let's also forward this to the same code path
as with `pytest-xdist`.
Warnings are a central part of Python, so much that Python itself has
command-line and environtment variables to handle warnings.
By moving the concept of warning handling into Config, it becomes natural to
filter warnings issued as early as possible, even before the "_pytest.warnings"
plugin is given a chance to spring into action. This also avoids the weird
coupling between config and the warnings plugin that was required before.

pytest has several instances where plugins set their own attributes on
objects they receive in hooks, like nodes and config. Since plugins are
detached from these object's definition by design, this causes a problem
for type checking because these attributes are not defined and mypy
complains.
Fix this by giving these objects a "store" which can be used by plugins
in a type-safe manner.
Currently this mechanism is private. We can consider exposing it at a
later point.
Use suggestion in review and use a subplugin so hooks will only be active
if we enable faulthandler ourselves.

* Add pytest-faulthandler files unchanged
* Adapt imports and tests
* Add code to skip registration of the external `pytest_faulthandler`
to avoid conflicts
