Since pytest now requires Python>=3.7, we can use the stdlib attrs
clone, dataclasses, instead of the OG package.
attrs is still somewhat nicer than dataclasses and has some extra
functionality, but for pytest usage there's not really a justification
IMO to impose the extra dependency on users when a standard alternative
exists.
The dummy modules we introduce in `insert_missing_modules` (due to #7856 and #7859)
would cause problems if the dummy modules actually end up replacing modules
which could be imported normally because they are available in `PYTHONPATH`.
Now we attempt to first import the module via normal mechanisms, and only
introduce the dummy modules if the intermediary modules don't actually exist.

On Windows, os.path.samefile returns false for paths mounted in UNC paths which
point to the same location.
I couldn't reproduce the actual case reported, but looking at the code it seems
this commit should fix the issue.
Fix#7678Fix#8076
When pytest was run on a directory containing a recursive symlink it failed
with ELOOP as the library was not able to determine the type of the
direntry:
src/_pytest/main.py:685: in collect
if not direntry.is_file():
E OSError: [Errno 40] Too many levels of symbolic links: '/home/florian/proj/pytest/tests/recursive'
This is fixed by handling ELOOP and other errors in the visit function in
pathlib.py, so the entries whose is_file() call raises an OSError with the
pre-defined list of error numbers will be exluded from the result.
The _ignore_errors function was copied from Lib/pathlib.py of cpython 3.9.
