This is a useful addition to the existing `listchain`. While `listchain`
returns top-to-bottom, `iterparents` is bottom-to-top and doesn't require
an internal full iteration + `reverse`.

--- Problem
Each fixture definition has a "visibility", the `FixtureDef.baseid`
attribute. This is nodeid-like string. When a certain `node` requests a
certain fixture name, we match node's nodeid against the fixture
definitions with this name.
The matching currently happens on the *textual* representation of the
nodeid - we split `node.nodeid` to its "parent nodeids" and then check
if the fixture's `baseid` is in there.
While this has worked so far, we really should try to avoid textual
manipulation of nodeids as much as possible. It has also caused problem
in an odd case of a `Package` in the root directory: the `Package` gets
nodeid `.`, while a `Module` in it gets nodeid `test_module.py`. And
textually, `.` is not a parent of `test_module.py`.
--- Solution
Avoid this entirely by just checking the node hierarchy itself. This is
made possible by the fact that we now have proper `Directory` nodes
(`Dir` or `Package`) for the entire hierarchy.
Also do the same for `_getautousenames` which is a similar deal.
The `iterparentnodeids` function is no longer used and is removed.
I think it's helpful to separate the node classes from the other
objects, as they have their own unique usage.
I've chosen not to alphabetize the order, but to use a logical order
instead.
Also slightly improve the docstrings.
TracebackEntry needs the excinfo for the `__tracebackhide__ = callback`
functionality, where `callback` accepts the excinfo.
Currently it achieves this by storing a weakref to the excinfo which
created it. I think this is not great, mixing layers and bloating the
objects.
Instead, have `ishidden` (and transitively, `Traceback.filter()`) take
the excinfo as a parameter.
By "empty traceback" I mean a traceback all of whose entries have been
filtered/cut/pruned out.
Currently, if an empty traceback needs to be repr'ed, the last entry
before the filtering is used instead (added in
accd962c9f).
Showing a hidden frame is not so good IMO. This commit does the
following instead:
1. Shows details of the exception.
2. Shows a message about how the full trace can be seen.
Example:
```
_____________ test _____________
E ZeroDivisionError: division by zero
All traceback entries are hidden. Pass `--full-trace` to see hidden and internal frames.
```
Also handles `--tb=native`, though there the `--full-trace` bit is not
shown.
This commit contains some pieces from
431ec6d34e (which has been reverted).
Helps towards fixing issue # 1904.

New versions of sphinx starting showing `__init__` parameters even when
we don't want them to show because they are private (have `_ispytest`
argument).
The only working solution I found was to switch to
`autodoc_typehints_description_target = "documented"` and explicitly
document parameters for which we want to show the types. It's a little
tedious and repetitive in some simple cases, but overall it results in
nicer API docs.

This is unfortunately a dependency on `py.path` which cannot be moved to
an external plugins or eased in any way, so has to be deprecated in
order for pytest to be able to eventually remove the dependency on `py`.
`reportinfo()` is the last remaining py.path-only code path in pytest,
i.e. the last piece holding back py.path deprecation. The problem with
it is that plugins/users use it from both sides -- implementing it
(returning the value) and using it (using the return value). Dealing
with implementers is easy enough -- allow to return `os.PathLike[str]`.
But for callers who expect strictly `py.path` this will break and
there's not really a good way to provide backward compat for this.
From analyzing a corpus of 680 pytest plugins, the vast majority of
`reportinfo` appearances are implementations, and the few callers don't
actually access the path part of the return tuple.
As for test suites that might access `reportinfo` (e.g. using
`request.node.reportinfo()` or other ways), that is much harder to
survey, but from the ones I searched, I only found case
(`pytest_teamcity`, but even then it uses `str(fspath)` so is unlikely
to be affected in practice). They are better served with using
`node.location` or `node.path` directly.
Therefore, just break it and change the return type to
`str|os.PathLike[str]`.
Refs #7259.
It is not clear yet how we should proceed with this deprecation
because `pytest.Item.reportinfo` is public API and returns a `py.path` object,
and is not clear how plugins and our examples should handle that.
Reverting just the deprecation aspect of #8251 so we can get a 7.0.0 release out.
We will reintroduce the deprecation later once we have a clear path moving forward with replacing `reportinfo`.

This type is most prominent in `pytest.raises` and we should allow to
refer to it by a public name.
The type is not in a perfectly "exposable" state. In particular:
- The `traceback` property with type `Traceback` which is derived from
the `py.code` API and exposes a bunch more types transitively. This
stuff is *not* exported and probably won't be.
- The `getrepr` method which probably should be private.
But they're already used in the wild so no point in just hiding them
now.
The __init__ API is hidden -- the public API for this are the `from_*`
classmethods.
