* Streaming request by async for.

* 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.

* 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.

* 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.

* 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.

* Ignore writing headers when in ASGI mode for streaming responses
* Move asgi set on streaming until after response type check
* Adds multidict==5.0.0 to pass tests
* Bump version to 20.9.1
* Socket binding implemented properly for IPv6 and UNIX sockets.
- app.run("::1") for IPv6
- app.run("unix:/tmp/server.sock") for UNIX sockets
- app.run("localhost") retains old functionality (randomly either IPv4 or IPv6)
Do note that IPv6 and UNIX sockets are not fully supported by other Sanic facilities.
In particular, request.server_name and request.server_port are currently unreliable.
* Fix Windows compatibility by not referring to socket.AF_UNIX unless needed.
* Compatibility fix.
* Fix test of existing unix socket.
* Cleaner unix socket removal.
* Remove unix socket on exit also with workers=1.
* More pedantic UNIX socket implementation.
* Refactor app to take unix= argument instead of unix:-prefixed host. Goin' fast @ unix-socket fixed.
* Linter
* Proxy properties cleanup. Slight changes of semantics. SERVER_NAME now overrides everything.
* Have server fill in connection info instead of request asking the socket.
- Would be a good idea to remove request.transport entirely but I didn't dare to touch it yet.
* Linter 💣🌟✊💀
* Fix typing issues. request.server_name returns empty string if host header is missing.
* Fix tests
* Tests were failing, fix connection info.
* Linter nazi says you need that empty line.
* Rename a to addr, leave client empty for unix sockets.
* Add --unix support when sanic is run as module.
* Remove remove_route, deprecated in 19.6.
* Improved unix socket binding.
* More robust creating and unlinking of sockets. Show proper and not temporary name in conn_info.
* Add comprehensive tests for unix socket mode.
* Hide some imports inside functions to avoid Windows failure.
* Mention unix socket mode in deployment docs.
* Fix merge commit.
* Make test_unix_connection_multiple_workers pickleable for spawn mode multiprocessing.

* Fixes ability to trigger "after_server_start", "before_server_stop", "after_server_stop" server events when using app.create_server to start your own asyncio_server
See example file run_async_advanced for a full example
* Fix a missing method on AsyncServer that some tests need
Add a tiny bit more documentation in-code
Change name of AsyncServerCoro to AsyncioServer
* This commit adds handlers for the asyncio/uvloop protocol callbacks for pause_writing and resume_writing.
These are needed for the correct functioning of built-in tcp flow-control provided by uvloop and asyncio.
This is somewhat of a breaking change, because the `write` function in user streaming callbacks now must be `await`ed.
This is necessary because it is possible now that the http protocol may be paused, and any calls to write may need to wait on an async event to be called to become unpaused.
Updated examples and tests to reflect this change.
This change does not apply to websocket connections. A change to websocket connections may be required to match this change.
* Fix a couple of PEP8 errors caused by previous rebase.
* update docs
add await syntax to response.write in response-streaming docs.
* remove commented out code from a test file
