See <code class="function">utrace_control</code> for detailed descriptions of each action. This is
encoded in the <em class="parameter"><code>action</code></em> argument and the return value for every callback
with a <span class="structname">u32</span> return value.

The order of these is important. When there is more than one engine,
each supplies its choice and the smallest value prevails.
