Update aiohttp to 3.8.1

[pyup-bot]

This PR updates aiohttp from 2.2.0 to 3.8.1.

Changelog

3.8.0

==================

Features
--------

- Added a ``GunicornWebWorker`` feature for extending the aiohttp server configuration by allowing the 'wsgi' coroutine to return ``web.AppRunner`` object.
`2988 <https://github.com/aio-libs/aiohttp/issues/2988>`_
- Switch from ``http-parser`` to ``llhttp``
`3561 <https://github.com/aio-libs/aiohttp/issues/3561>`_
- Use Brotli instead of brotlipy
`3803 <https://github.com/aio-libs/aiohttp/issues/3803>`_
- Disable implicit switch-back to pure python mode. The build fails loudly if aiohttp
cannot be compiled with C Accelerators.  Use AIOHTTP_NO_EXTENSIONS=1 to explicitly
disable C Extensions complication and switch to Pure-Python mode.  Note that Pure-Python
mode is significantly slower than compiled one.
`3828 <https://github.com/aio-libs/aiohttp/issues/3828>`_
- Make access log use local time with timezone
`3853 <https://github.com/aio-libs/aiohttp/issues/3853>`_
- Implemented ``readuntil`` in ``StreamResponse``
`4054 <https://github.com/aio-libs/aiohttp/issues/4054>`_
- FileResponse now supports ETag.
`4594 <https://github.com/aio-libs/aiohttp/issues/4594>`_
- Add a request handler type alias ``aiohttp.typedefs.Handler``.
`4686 <https://github.com/aio-libs/aiohttp/issues/4686>`_
- ``AioHTTPTestCase`` is more async friendly now.

For people who use unittest and are used to use :py:exc:`~unittest.TestCase`
it will be easier to write new test cases like the sync version of the :py:exc:`~unittest.TestCase` class,
without using the decorator `unittest_run_loop`, just `async def test_*`.
The only difference is that for the people using python3.7 and below a new dependency is needed, it is ``asynctestcase``.
`4700 <https://github.com/aio-libs/aiohttp/issues/4700>`_
- Add validation of HTTP header keys and values to prevent header injection.
`4818 <https://github.com/aio-libs/aiohttp/issues/4818>`_
- Add predicate to ``AbstractCookieJar.clear``.
Add ``AbstractCookieJar.clear_domain`` to clean all domain and subdomains cookies only.
`4942 <https://github.com/aio-libs/aiohttp/issues/4942>`_
- Add keepalive_timeout parameter to web.run_app.
`5094 <https://github.com/aio-libs/aiohttp/issues/5094>`_
- Tracing for client sent headers
`5105 <https://github.com/aio-libs/aiohttp/issues/5105>`_
- Make type hints for http parser stricter
`5267 <https://github.com/aio-libs/aiohttp/issues/5267>`_
- Add final declarations for constants.
`5275 <https://github.com/aio-libs/aiohttp/issues/5275>`_
- Switch to external frozenlist and aiosignal libraries.
`5293 <https://github.com/aio-libs/aiohttp/issues/5293>`_
- Don't send secure cookies by insecure transports.

By default, the transport is secure if https or wss scheme is used.
Use `CookieJar(treat_as_secure_origin="http://127.0.0.1")` to override the default security checker.
`5571 <https://github.com/aio-libs/aiohttp/issues/5571>`_
- Always create a new event loop in ``aiohttp.web.run_app()``.
This adds better compatibility with ``asyncio.run()`` or if trying to run multiple apps in sequence.
`5572 <https://github.com/aio-libs/aiohttp/issues/5572>`_
- Add ``aiohttp.pytest_plugin.AiohttpClient`` for static typing of pytest plugin.
`5585 <https://github.com/aio-libs/aiohttp/issues/5585>`_
- Added a ``socket_factory`` argument to ``BaseTestServer``.
`5844 <https://github.com/aio-libs/aiohttp/issues/5844>`_
- Add compression strategy parameter to enable_compression method.
`5909 <https://github.com/aio-libs/aiohttp/issues/5909>`_

- Added optional auto_decompress argument for HttpRequestParser
`5957 <https://github.com/aio-libs/aiohttp/issues/5957>`_
- Added support for HTTPS proxies to the extent CPython's
:py:mod:`asyncio` supports it -- by :user:`bmbouter`,
:user:`jborean93` and :user:`webknjaz`.
`5992 <https://github.com/aio-libs/aiohttp/issues/5992>`_
- Added ``base_url`` parameter to the initializer of :class:`~aiohttp.ClientSession`.
`6013 <https://github.com/aio-libs/aiohttp/issues/6013>`_
- Add Trove classifier and create binary wheels for 3.10. -- :user:`hugovk`.
`6079 <https://github.com/aio-libs/aiohttp/issues/6079>`_

`5877 <https://github.com/aio-libs/aiohttp/issues/5877>`_
- Fix the error in handling the return value of `getaddrinfo`.
`getaddrinfo` will return an `(int, bytes)` tuple, if CPython could not handle the address family.

3.7.4

==================

Bugfixes
--------

- **(SECURITY BUG)** Started preventing open redirects in the
``aiohttp.web.normalize_path_middleware`` middleware. For
more details, see
https://github.com/aio-libs/aiohttp/security/advisories/GHSA-v6wp-4m6f-gcjg.

Thanks to `Beast Glatisant <https://github.com/g147>`__ for
finding the first instance of this issue and `Jelmer Vernooij
<https://jelmer.uk/>`__ for reporting and tracking it down
in aiohttp.
`5497 <https://github.com/aio-libs/aiohttp/issues/5497>`_
- Fix interpretation difference of the pure-Python and the Cython-based
HTTP parsers construct a ``yarl.URL`` object for HTTP request-target.

Before this fix, the Python parser would turn the URI's absolute-path
for ``//some-path`` into ``/`` while the Cython code preserved it as
``//some-path``. Now, both do the latter.

Reuse a protocol based on keepalive in headers is unreliable.
For example, uWSGI will not support keepalive even it serves a
HTTP 1.1 request, except explicitly configure uWSGI with a
``--http-keepalive`` option.

Servers designed like uWSGI could cause aiohttp intermittently
raise a ConnectionResetException when the protocol poll runs
out and some protocol is reused.

3.1.0

==================

Welcome to aiohttp 3.1 release.

This is an *incremental* release, fully backward compatible with *aiohttp 3.0*.

But we have added several new features.

The most visible one is ``app.add_routes()`` (an alias for existing
``app.router.add_routes()``. The addition is very important because
all *aiohttp* docs now uses ``app.add_routes()`` call in code
snippets. All your existing code still do register routes / resource
without any warning but you've got the idea for a favorite way: noisy
``app.router.add_get()`` is replaced by ``app.add_routes()``.

The library does not make a preference between decorators::

routes = web.RouteTableDef()

routes.get('/')
async def hello(request):
    return web.Response(text="Hello, world")

app.add_routes(routes)

and route tables as a list::

async def hello(request):
    return web.Response(text="Hello, world")

app.add_routes([web.get('/', hello)])

Both ways are equal, user may decide basing on own code taste.

Also we have a lot of minor features, bug fixes and documentation
updates, see below.

Features
--------

- Relax JSON content-type checking in the ``ClientResponse.json()`` to allow
"application/xxx+json" instead of strict "application/json". (`2206 <https://github.com/aio-libs/aiohttp/pull/2206>`_)
- Bump C HTTP parser to version 2.8 (`2730 <https://github.com/aio-libs/aiohttp/pull/2730>`_)

worker. (`2739 <https://github.com/aio-libs/aiohttp/pull/2739>`_)
- Implement application cleanup context (``app.cleanup_ctx`` property). (`2747 <https://github.com/aio-libs/aiohttp/pull/2747>`_)
- Make ``writer.write_headers`` a coroutine. (`2762 <https://github.com/aio-libs/aiohttp/pull/2762>`_)

change affects aiohttp test utils but backward compatibility is not broken
for 99.99% of use cases. (`2804 <https://github.com/aio-libs/aiohttp/pull/2804>`_)
- Refactor ``ClientResponse`` constructor: make logically required constructor
arguments mandatory, drop ``_post_init()`` method. (`2820 <https://github.com/aio-libs/aiohttp/pull/2820>`_)
- Use ``app.add_routes()`` in server docs everywhere (`2830 <https://github.com/aio-libs/aiohttp/pull/2830>`_)
