23/* Initialise response headers, or msg/response pairs.
Eliot Blennerhassett14652e62011-02-10 17:26:01 +130024Note that it is valid to just init a response e.g. when a lower level is
25preparing a response to a message.
26However, when sending a message, a matching response buffer must always be
27prepared.
