For better osmo-bts usage, I split the gain

OpenBTS usage, but that fix should really be in core and not the

Well, since we don't control the core of OpenBTS, could we make the
transceiver compatible with both ways?
We would need to change the gain control interface or set something at
compile time. Basically, right now there is no way for the transceiver
to distinguish between a set-all-gains and set-channel-gain request.
Also setting the Tx/Rx gains is a proper way for
Multi-ARFCN version
where ARFCN are actually on the same TRX. So we have to make this
compatible with both ways anyway. E.g. we could introduce a new
command to configure transceiver regarding TRXs.
Assuming OpenBTS core cannot be touched, we can either add a new
set-channal-gain command or a second boolean argument on the existing
SETRXGAIN command. For the latter case, OpenBTS would ignore the
second argument.
