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.
