Support for the Yaesu FTdx3000 and similar rigs via HRD

Browse Source 
There  is an  outstanding  issue with  the FTdx3000  via  HRD in  that
setting  the  "other" VFO  mode  doesn't  work.   This appears  to  be
insoluable and the  only current option is to set  "Mode" to "None" in
WSJT-X leaving mode  setting to the user. As it  happens the best mode
combo on this rig  is probably DATA-U on Tx and USB  on Rx which would
require "Mode" as "None" anyway.

This change is quite large  including several general strategy changes
in an attempt to make the HRD interface more generic and more robust.

Also cleaned up  trace output removing stuff that is  working and just
clutters output.

Merged from wsjtx-1.4 branch.
