CAT protocols that don't allow direct addressing of VFOs require that
the "other" VFO be queried or set via a select then get/set then
select back to original or swap then get/set then swap again. When
both frequncy and mode need to be set the sequences can be optimized
if a single funciton is avaiable.
This enhancement adds those single functions rig_set_split_freq_mode()
and rig_get_split_freq_mode() with a default impelementation that
calls the individual rig_{get,set}_split_{freq,mode}() functions. Back
ends can choose to implement an optimized version which is used
instead of the default if present.
Using these functions when an optimized implementation is available
allows the TX VFO's frequency and mode to be set in a single operation
with only one VFO exchange or selection either side of the
operation. Many CAT protocols are very efficient when getting or
setting both frequency and mode and some even combine the two in a
single command.
The letters 'K' and 'k' are used for the rigctl short command name for
these functions.
to set_split_vfo/get_split_vfo, and take an extra transmit vfo arg.
Ascending compatibility is retained at the API frontend level.
NOTE: only function name has changed. The backends do not implement
necessarily the new semantic (the extra tx vfo is just ignored).

- rig_set_channel and rig_get_channel can now target VFO, besides memories
- emulation of set_channel and get_channel has been kept in generic routines.
Added in these routines the support for ext_levels.
