Davide De Rosa e6dd4de472 Move control data parsing 2018-09-19 22:04:52 +02:00
Davide De Rosa 19ce7de819 Encapsulate control state into ControlChannel
First step: variables + mutating funcs.

Davide De Rosa d80c0b5460 Move in/out states to a generic struct 2018-09-19 22:04:52 +02:00
Davide De Rosa 2bd9484a43 Move ControlPacket serialization to Obj-C
Additionally, make sessionId non-optional in control packets. They
must have it, therefore treat a missing sessionId as a programming
error instead.

Reuse routines for acks to make PacketMacros the only point of
packets serialization.
