Use 4 different Costas arrays to prevent false syncs as received frames move
...
through the analysis window.
Add a random 77-bit vector to each message so that tone transitions occur
even if the message contains a long string of 0 or 1 (like a CQ).
Add alternative sync calculation as an option (sync2), for testing.
Add basic framework for AP decoding.

Make the UDP protocol Clear (3) message two-way
...
External servers can clear either or both of the Band Activity and Rx
Frequency decodes windows. This was requested by Dave, AA6YQ, so that
DX Lab Suite applications can clear old decodes on band changes to
ensure that decode highlighing is consistent.

Remove normal mouse double-click action for decode display windows
...
The normal action selects the word under the mouse pointer and this
disrupts callsign highlighting. Normal single-click selection
behaviour is unchanged so text can still be selected using the mouse
and copied if desired.

Allow for tx periods shorter than the audio buffer size
...
Audio will not start until at least one buffer full is achieved and as
we use a large target latency of 2s to minimize CPU usage and glitches
we must pad with silence when the QAudioOutput pulls buffers from the
Modulator i/o device. This is all necessary with pulseaudio using the
underlying o/s ALSA device, i.e. on Linux.
