SQLClient exists as a wrapper around SQL IPC to provide a bit friendlier interface for clients to deal with. Though right now, it mostly forwards values as-is from IPC to the clients. This makes it a bit verbose to add values to IPC responses, as we then have to add it to the callbacks used by all clients. It's also a bit confusing seeing a sea of "auto" as the parameter types for these callbacks. This patch moves these response values to named structures instead. This will allow adding values without needing to simultaneously update all clients. We can then separately handle the new values in interested clients only.
