Streaming Server (#1876) 
* Streaming request by async for.

* Make all requests streaming and preload body for non-streaming handlers.

* Cleanup of code and avoid mixing streaming responses.

* Async http protocol loop.

* Change of test: don't require early bad request error but only after CRLF-CRLF.

* Add back streaming requests.

* Rewritten request body parser.

* Misc. cleanup, down to 4 failing tests.

* All tests OK.

* Entirely remove request body queue.

* Let black f*ckup the layout

* Better testing error messages on protocol errors.

* Remove StreamBuffer tests because the type is about to be removed.

* Remove tests using the deprecated get_headers function that can no longer be supported. Chunked mode is now autodetected, so do not put content-length header if chunked mode is preferred.

* Major refactoring of HTTP protocol handling (new module http.py added), all requests made streaming. A few compatibility issues and a lot of cleanup to be done remain, 16 tests failing.

* Terminate check_timeouts once connection_task finishes.

* Code cleanup, 14 tests failing.

* Much cleanup, 12 failing...

* Even more cleanup and error checking, 8 failing tests.

* Remove keep-alive header from responses. First of all, it should say timeout=<value> which wasn't the case with existing implementation, and secondly none of the other web servers I tried include this header.

* Everything but CustomServer OK.

* Linter

* Disable custom protocol test

* Remove unnecessary variables, optimise performance.

* A test was missing that body_init/body_push/body_finish are never called. Rewritten using receive_body and case switching to make it fail if bypassed.

* Minor fixes.

* Remove unused code.

* Py 3.8 check for deprecated loop argument.

* Fix a middleware cancellation handling test with py38.

* Linter 'n fixes

* Typing

* Stricter handling of request header size

* More specific error messages on Payload Too Large.

* Init http.response = None

* Messages further tuned.

* Always try to consume request body, plus minor cleanup.

* Add a missing check in case of close_if_idle on a dead connection.

* Avoid error messages on PayloadTooLarge.

* Add test for new API.

* json takes str, not bytes

* Default to no maximum request size for streaming handlers.

* Fix chunked mode crash.

* Header values should be strictly ASCII but both UTF-8 and Latin-1 exist. Use UTF-8B to
cope with all.

* Refactoring and cleanup.

* Unify response header processing of ASGI and asyncio modes.

* Avoid special handling of StreamingHTTPResponse.

* 35 % speedup in HTTP/1.1 response formatting (not so much overall effect).

* Duplicate set-cookie headers were being produced.

* Cleanup processed_headers some more.

* Linting

* Import ordering

* Response middleware ran by async request.respond().

* Need to check if transport is closing to avoid getting stuck in sending loops after peer has disconnected.

* Middleware and error handling refactoring.

* Linter

* Fix tracking of HTTP stage when writing to transport fails.

* Add clarifying comment

* Add a check for request body functions and a test for NotImplementedError.

* Linter and typing

* These must be tuples + hack mypy warnings away.

* New streaming test and minor fixes.

* Constant receive buffer size.

* 256 KiB send and receive buffers.

* Revert "256 KiB send and receive buffers."

This reverts commit abc1e3edb2.

* app.handle_exception already sends the response.

* Improved handling of errors during request.

* An odd hack to avoid an httpx limitation that causes test failures.

* Limit request header size to 8 KiB at most.

* Remove unnecessary use of format string.

* Cleanup tests

* Remove artifact

* Fix type checking

* Mark test for skipping

* Cleanup some edge cases

* Add ignore_body flag to safe methods

* Add unit tests for timeout logic

* Add unit tests for timeout logic

* Fix Mock usage in timeout test

* Change logging test to only logger in handler

* Windows py3.8 logging issue with current testing client

* Add test_header_size_exceeded

* Resolve merge conflicts

* Add request middleware to hard exception handling

* Add request middleware to hard exception handling

* Request middleware on exception handlers

* Linting

* Cleanup deprecations
