This could be enhanced when the trace-event namespace is partitioned into a
group and an ID within that group. In such a case, marking a group as enabled
would automatically enable all trace-events listed under it.

set at config-time.
Also, this adds monitor sub-command 'set' to trace-file commands to
dynamically change trace log file at runtime.
Eg,
(qemu)trace-file set FILENAME
This allows one to set trace outputs to FILENAME from the default
specified at startup.
