This allows responses to be sent to the client even when data is only partially read, significantly improving the experience for the client from one with a "connection closed" error to one with a proper response. The consequence is a lifetime in 'Data'. Though other non-lifetime-introducing solutions exist, the introduction of a lifetime to 'Data' is a longstanding desire as it prevents smuggling 'Data' into a longer-lived context. Use of 'Data' in that context was unspecified with various runtime consequences. The addition of a lifetime bound by the request prevents this error statically. In summary, the changes are: * Clients receive responses even when data isn't fully read. * 'Data' becomes 'Data<'r>'. 'FromData' changes accordingly. * Route 'Outcome's are strictly tied to the request lifetime. Tangentially, the invalid length form field validation error message has improved to format length in byte units if it exceeds 1024.
