share MessageEngine instance

Share MessageEngine instance among clients in the
same process using a common socket (same url).

- add MessageEngineFactory class;
- extend std::unordered_map<> to use QString as
key;
- use std::shared_ptr<MessageEngine> to share
ownership among MessageEngineFactory and the
engine clients;
- force MessagEngine parent object null to avoid
life cycle dependency on a parent;
- protect insertions & deletions in m_calls map;

Also, not directly related but as part of testing
these changes: cleanup on voice to remove
superflous model sorting (there's just one voice
model for alexa voice agent).
