I'll take care of this.  There's a lot of cruft in there that could
have been removed four years ago when the mythlogserver program was
removed.

I just spent time removing the old qjsonwrapper external qt4->qt5 json
bridge code.  Since that code was used as the connection from
logging.cpp to loggingserver.cpp, that got me looking at all the
unnecessary code in loggingserver.cpp.  (I.E. There's no need to
convert an object to json and back if all the code executes in the same
process, and there's no need for client->logger and logger->client maps
if there's only ever one client.)  I punted on cleaning up that code
four years ago, so now seems like a good time for me to finish the
removal of the mythlogserver program.
