* Replaced parameter name "self" with "cls" for a few class methods. Pyright emits a warning if a class method doesn't follow the PEP 8 standard where the first parameter is named "cls" for a class method. This change eliminates these warnings.
* Missed a file.

* PEP 484 says that type checkers should assume that all types used in a stub should use forward declarations even though they are not quoted. This stub is using the symbol "type" within the context of a class scope. The "type" symbol is declared within this scope, so pyright assumes that the forward declaration should be used. The solution is to define a symbol with a different name in the outer scope to avoid the name conflict.
* Fixed import sort order.

* Pyright detects and reports cases where a multi-part module name is accessed but is not explicitly imported. These are dangerous because they rely on import resolution ordering within a program, which can easily change. This change eliminates errors detected by pyright.
* Fixed regression caught by CI test.
* Fixed black formatting issues.

This makes mypy think that conditions like
parameter.kind is Parameter.POSITIONAL_OR_KEYWORD
are always false, which triggers `unreachable` warnings, among other
problems.
* Enable some branches for Python2 pathlib2
* Define an alias _PathLike, instead of using multiple branches
* Drop a Python 3.4 branch (the Python 2 branch is identical to
the 3.5+ branch)
* Move Path.__new__ to the top
Add support for the following syslog facilities:
- LOG_NTP
- LOG_SECURITY
- LOG_CONSOLE
- LOG_SOLCRON
In addition, reorder the entries to match the CPython implementation to
make it easier to read.
typing.Mapping is not a protocol, which has caused problems in the past.
(E.g. python/typeshed#3569, see also python/typeshed#3576.) This
introduces a few narrow protocols to _typeshed.pyi that can be used in
place of Mapping.
Not all uses of Mapping can be replaced. For example, cgi.FieldStorage
explictly checks whether the supplied headers argument is a Mapping
instance.
This doesn't cover everything but it means it a lot of common usages the type will be slightly more useful

According to the official docs, "user can be a system user name or a uid;
the same applies to group".

Fixes#4288.
- Default imports to THIRD_PARTY, so in effect we merge the FIRST_PARTY and THIRD_PARTY stubs. This means import order is no longer affected by whether typing_extensions is installed locally.
- Treat typing_extensions, _typeshed and some others as standard library modules.
Note that isort master is very different from the latest release; we'll have to do something
different if and when the next isort release comes out.
The following code produces an error in mypy:
import asyncio
from asyncio.subprocess import PIPE
async def main() -> None:
proc = await asyncio.create_subprocess_shell("ls -l", stdout=PIPE)
assert proc.stdout is not None
async for line in proc.stdout:
print(line.decode())
await proc.wait()
asyncio.run(main())
$ mypy --strict file.py
file.py:8: error: "StreamReader" has no attribute "__aiter__" (not async iterable)
This commits fixes this by adding __aiter__/__anext__ methods that are
needed for async iterator protocol.
