* "Force" nvlist wrapper.
*
* These functions wrap the nvlist_* functions with assertions that assume
* the operation is successful. This allows the caller's code to be much
* more readable, especially for the fnvlist_lookup_* and fnvpair_value_*
* functions, which can return the requested value (rather than filling in
* a pointer).
*
* These functions use NV_UNIQUE_NAME, encoding NV_ENCODE_NATIVE, and allocate
* with KM_SLEEP.
*
* More wrappers should be added as needed -- for example
* nvlist_lookup_*_array and nvpair_value_*_array.
