Build now creates and installs a UDP library that contains the server side of the UDP messaging facility. This library is used by the udp_daemon and message_aggregator reference examples. The new library is currently a static archive but can also be built as a shared library. The library allows third party Qt applications to easily access UDP messages from WSJT-X. Refactored the message_aggregator reference example to split out classes into separate translation units. Added new functionality to exercise the new UDP status fields, highlight own call, CQ/QRZ messages and decodes near Rx DF. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@6691 ab8295b8-cf94-4d9e-aec4-7959e3be5d79
