DISPATCH-1788: fixes and testcases for HTTP/1.0 support
This closes #859
> HTTP1.x adaptor fails to honor HTTP/1.0 connection semantics
> ------------------------------------------------------------
>
> Key: DISPATCH-1788
> URL: https://issues.apache.org/jira/browse/DISPATCH-1788
> Project: Qpid Dispatch
> Issue Type: Bug
> Components: Protocol Adaptors
> Affects Versions: 1.15.0
> Reporter: Ken Giusti
> Assignee: Ken Giusti
> Priority: Major
> Labels: HTTP/1.x
> Fix For: Backlog
>
>
> The HTTP/1.x codec does not handle HTTP/1.0 connection lifecycle correctly.
> There is a race when the HTTP/1.0 server sends a response with a valid
> content-length to a router that has queued multiple outstanding request
> messages. The adaptor does not wait for the connection to close after the
> response is received and begins to send the next pending request as the
> server is closing the connection.
>
> From RFC7230, Persistence:
>
> {quote}A recipient determines whether a connection is persistent or not based
> on the most recently received message’s protocol version and Connection
> header field (if any):
> o If the "close" connection option is present, the connection will not
> persist after the current response; else,
> o If the received protocol is HTTP/1.1 (or later), the connection will
> persist after the current response; else,
> o If the received protocol is HTTP/1.0, the "keep-alive" connection option is
> present, the recipient is not a proxy, and the recipient wishes to honor the
> HTTP/1.0 "keep-alive" mechanism, the connection will persist after the
> current response; otherwise,
> o The connection will close after the current response. A client MAY send
> additional requests on a persistent connection until it sends or receives a
> "close" connection option or receives an HTTP/1.0 response without a
> "keep-alive" connection option.
> {quote}
