trace: add "-trace events" argument to control initial state
The "-trace events" argument can be used to provide a file with a list of trace
event names that will be enabled prior to starting execution, thus providing
early tracing.
This saves the user from manually toggling event states through the monitor
interface or whichever backend-specific interface.
