wext: uninline stream addition functions
With 78, 111 and 85 bytes respectively (on x86-64), the functions iwe_stream_add_event(), iwe_stream_add_point() and iwe_stream_add_value() really shouldn't be inlines. It appears that at least my compiler already decided the same, and created a single instance of each one of them for each file using it, but that's still a number of instances in the system overall, which this reduces.
