README: HTTP/1.1 in the intro, feature list, module list, browser-build
exclusions, dependencies and test list, plus a Components section
covering both classes, the standalone codec, what is and is not
implemented, the smuggling-shaped inputs that are rejected, and an
explicit note that this path is plaintext and belongs behind a TLS
terminator.
ClientHTTP1::timeout was hard-coded and invisible; make it a public
member alongside `limits`, mirroring the listener's timeouts.
Also pipelining coverage in ShouldSendRecieveHTTP1: two requests written
before either is answered, driven from a raw socket since ClientHTTP1
waits for each response.
