Module message 

Control message types with encode/decode. Draft-11 control message encoding and decoding.

Key changes from draft-09/10:

• Setup IDs: 0x40/0x41 -> 0x20/0x21
• subscribe_id -> request_id throughout
• MaxSubscribeId -> MaxRequestId, SubscribesBlocked -> RequestsBlocked
• Subscribe gains track_alias and forward fields; group_order/forward/filter_type as VarInt
• SubscribeOk: no track_alias; group_order/content_exists as VarInt
• SubscribeError gains trailing track_alias
• SubscribeDone gains stream_count
• SubscribeUpdate uses start_group/start_object (not Location); forward as VarInt
• Announce gains request_id; AnnounceOk/AnnounceError use request_id
• AnnounceCancel: namespace + error_code + reason_phrase
• SubscribeAnnounces gains request_id
• TrackStatusRequest gains request_id and parameters
• TrackStatus restructured: request_id + status_code + largest_location + parameters
• Fetch restructured: 3 fetch types (Standalone, RelativeJoining, AbsoluteJoining)
• FetchOk: group_order + end_of_track + end_location (no track_alias)
• Uses even/odd KVP encoding (not d07 format)
• Framing: type_id(vi) + payload_length(16) + payload
