See also #2331 and #2090

Kick-off pathlib autofix. The others could mostly be implemented in the same logic, but perhaps good to test with only this small subset to see what occurs in the wild.

PTH201-205:

  • Simplify path constructor Path(".") to Path()
  • Replace os.path.getsize with Path.stat()
  • Using PTH2XX rather than FURBXXX (rules originate from refurb) to keep all pathlib logic together

Autofix for:

  • PTH201: Path(".") to Path()
  • PTH109: os.path.getcwd(x) to Path(x).cwd()

Nested calls are unwrapped:

  • Path(os.path.getcwd(x)) => Path(x).cwd()

Promote get_member_import_name_alias from pylint to ast.helpers

We should finally be able to support this once #3787 lands.

@sbrugman just to remind you that #3787 was merged and I think you can get the ball rolling again on this PR.

Anyone interested, feel free to pick up where this PR left off (@aqeelat perhaps?). I'd like to work on it, but do not expect it to fit soon.

I honestly have 0 rust experience and I'm not comfortable taking over.

@sbrugman - Should we close this out given that it's being ported over in chunks to new PRs?
