Uvicorn (almost) always used chunked encoding (even with HTTP 1.0)

[mkiesel]

Because of https://github.com/encode/uvicorn/blob/5e33d430f13622c8363fe74d97963ab37f3df3c2/uvicorn/protocols/http/httptools_impl.py#L505 , Uvicorn uses chunked encoding by default. However, HTTP 1.0 doesn't support chunked encoding, and quite a few legacy devices (e.g., music streaming devices) don't either. It would be good if Uvicorn supported both HTTP 1.0 and legacy devices (the latter probably via some "don't use chunked encoding" flag).

Related to https://github.com/encode/uvicorn/pull/1360/files which also contains a workaround.

Maybe try with --http h11 which is more compliant. Make sure the client must be HTTP/1.0.
