Fix declarations after statements
Remove some !rig checks...we either don't need them or need them everywhere with a new error code
If you pass a NULL rig you get what you deserve :-)
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
There was an inconsistency in whether the CAT terminator character is
included in returned messages. It now follows the comment in
kenwood_transaction() i.e. strips of the terminator and returns a
message length that reflects that.
