Sergio Benitez 4c6562cd29 Drop 'Data' after sending a response, not before.
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.
