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
This change allows the set_mode functions to leave the rig passband
unchanged if required. For the few rigs that do not have explcit
passband width control either current state is read and rewritten or a
"normal" width is chosen e.g. select a normal width when there is a
choice like CW and CW-NARROW.
Kenwood, modern Yaesu rigs and many SDRs use an auto information
mechanism that broadcasts unsolicited rig state changes, Hamlib does
not support this and turns off the function. Because several passive
devices rely on this information to detect band changes for example
this change adds code to save the AI state on start up and restores it
on exit. These devices do no need the broadcasts since when an
application using Hamlib is running as necessary state polling by the
application provides continuous rig state updates.
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.
