* Rotator Caps
* \struct rot_caps

* Fields that need to be modifiable by the application are
* copied into the struct rot_state, which is a kind of private
* of the ROT instance.
* This way, you can have several rigs running within the same application,
* sharing the struct rot_caps of the backend, while keeping their own
* customized data.
* NB: don't move fields around, as backend depends on it when initializing
* their caps.
