Expose libresapi for distant chat

Added macro to deprecate symbols usage in a crossplatform way.
Deprecated Request::mMethod and related stuff that make implementation
 more complex without advantage.
Added /chat/{initiate_distant_chat, distant_chat_status,
 close_distant_chat} to libresapi.
Solved subtle bug in ChatId::ChatId(std::string str) that caused zeroed
 DistantChatPeerId being created.
