This found tons of errors in rig_debug statements
So this patch cleans up all the files that were producing warnings or errors
This should fix a few segfaults when running with debug turned on
SF Bug ID 3527331
Action: Using rigctl, request signal strength (STRENGTH) for
a low signal level (~ < -100 dBm)
Expected result: Read a signal level of -100 or less
Actual result: Impossibly large negative value is returned.
Error found in initialization of a variable. Some (useful)
instrumentation was also added to help with future debugging.
