See discussion ably/realtime#522 Since we now keep the old transport active until it becomes idle, if a message hangs on the old transport resulting in it failing, when that happens it'll still be the active protocol, so deactivateTransport will requeue that message and clear the message from that protocol (allowing it to become idle and the upgrade transport to take over).
Four main changes: - Treat channelstate operations (attach/detach) and sync separately. This solves the bug where a sync ending would incorrectly remove the lock of a pending detach (#285). - Only set the lock once have actually sent an attaching or detaching message. The purpose of the mechanism is for connectionManager to decide when it's safe to upgrade. Before, channel might be inProgress and in the attaching state without any pending operations, eg if attached while the connection state is connecting. Since the upgrade transport now waits for nopending before activating, this caused a deadlock if an attach request timed out: checkPendingState is waiting for transport.active, which is waiting for nopending. Now, setting inProgress is only done once the a message has been sent. - Additionally we now start the statetimer when the message is sent (if it's not already running) - before, if an attach was queued due to not being connected, the timer would never be set, even on connected. - Checkpendingstate now happens a tick after transport.active, to give connectionManager finish activating the transport and setting the connection state (before, if not on upgrade, it would trigger while connection state was still 'connecting')
