Previously the body reader would initialize to HTTP/1.0 mode when the upgrade request header is found. Now the reader is only converted to that mode when both the upgrade header and 101 is received.
Because pipelining support is not yet fully implemented, pingora should avoid trying to process any pipelined message read alongside the current request. The session's connection will be closed and marked un-reusable.
Creates a pipe subrequest state machine utility to be able to treat the subrequest as a "pipe" (sending request body and writing response tasks directly from the subrequest). Also adds a handler to be able to propagate the downstream / final proxy error that a subrequest server session encounters to the pipe state machine. The subrequest pipe is also allowed to receive a preset input body, which may also be created from a previously captured downstream session body. In this case the captured session body may be reused for multiple "chained" subrequests. Co-authored-by: Matthew Gumport <mbg@cloudflare.com>
UpgradedBody was incorrectly no longer invoked for upstream response body filters or for downstream modules. Additionally allow supporting the rare case where UpgradedBody may be cached.
