Replace the separate pointer+length field pairs in dns_rdata_nsec3_t (salt/salt_length, next/next_length, typebits/len) and dns_rdata_nsec3param_t (salt/salt_length) with isc_region_t. This makes the structs self-describing and eliminates a class of length-mismatch bugs. The dns_zone_setnsec3param() signature is updated to take isc_region_t *salt instead of separate saltlen and salt arguments. Function signatures for dns_nsec3_addnsec3, dns_db_getnsec3parameters, and related internal functions still use separate pointer+length pairs and should be updated in a follow-up.
