p3ChatService support async distant chat via Gxs

Browse source 
To implement async distant chat p3ChatService use p3GxsMails in a similar
way that has been done with p3MsgService tought as p3ChatService was not
thinked for async comunication in the first place the result is quite
clumsy. A proper chat service should be rewritten from scratch in the near
future, with proper chat history and other desiderables features.
deprecated empty p3ChatService::locked_storeIncomingMsg(...)
