Send status information to UDP server

Browse Source 
To  facilitate interaction  with other  applications WSJT-X  now sends
status  updates  to  a  predefined   UDP  server  or  multicast  group
address. The  status updates include the  information currently posted
to  the  decodes.txt and  wsjtx_status.txt  files.   An optional  back
communications  channel is  also implemented  allowing the  UDP server
application to control some basic actions in WSJT-X.

A reference implementaion of a typical UDP server written in C++ using
Qt is  provided to demonstrate  these facilities. This  application is
not intended  as a user  tool but  only as an  example of how  a third
party application may interact with WSJT-X.

The  UDP messages  Use QDataStream  based serialization.  Messages are
documented in  NetworkMessage.hpp along with some  helper classes that
simplify the building and decoding of messages.

Two  message  handling  classes   are  introduced,  MessageClient  and
MessageServer.  WSJT-X uses the MessageClient class to manage outgoing
and  incoming  UDP  messages   that  allow  communication  with  other
applications.   The MessageServer  class implements  the kind  of code
that a  potential cooperating  application might use.   Although these
classes  use  Qt serialization  facilities,  the  message formats  are
easily  read and  written  by  applications that  do  not  use the  Qt
framework.

MessageAggregator   is   a   demonstration   application   that   uses
MessageServer and  presents a GUI  that displays messages from  one or
more  WSJT-X instances  and  allows sending  back a  CQ  or QRZ  reply
invocation  by double  clicking  a decode.   This  application is  not
intended as  a user facing tool  but rather as a  demonstration of the
WSJT-X UDP messaging facility. It  also demonstrates being a multicast
UDP server by allowing multiple instances to run concurrently. This is
enabled by using an appropriate  multicast group address as the server
address.  Cooperating   applications  need  not   implement  multicast
techniques but  it is recomended  otherwise only a  single appliaction
can act as a broadcast message (from WSJT-X) recipient.

//
// MessageAggregator - an example application that utilizes the WSJT-X
// messaging facility
//
// This application is only provided as a simple GUI application
// example to demonstrate the WSJT-X messaging facility. It allows the
// user to set the server details either as a unicast UDP server or,
// if a multicast group address is provided, as a multicast server.
// The benefit of the multicast server is that multiple servers can be
// active at once each receiving all WSJT-X broadcast messages and
// each able to respond to individual WSJT_X clients. To utilize the
// multicast group features each WSJT-X client must set the same
// multicast group address as the UDP server address for example
// 239.255.0.0 for a site local multicast group.
//
// The UI is a small panel to input the service port number and
// optionally the multicast group address. Below that a table
// representing the log entries where any QSO logged messages
// broadcast from WSJT-X clients are displayed. The bottom of the
// application main window is a dock area where a dock window will
// appear for each WSJT-X client, this window contains a table of the
// current decode messages broadcast from that WSJT-X client and a
// status line showing the status update messages broadcast from the
// WSJT_X client. The dock windows may be arranged in a tab bar, side
// by side, below each other or, completely detached from the dock
// area as floating windows. Double clicking the dock window title bar
// or dragging and dropping with the mouse allows these different
// arrangements.
//
// The application also provides a simple menu bar including a view
// menu that allows each dock window to be hidden or revealed.
