Extend UDP status message - added Rx/Tx DF, call and grid information

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.
