tracing: add filter event logic to special, mmiotrace and boot tracers

Now that the pluging tracers use macros to create the structures and
automate the exporting of their formats to the format files, they also
automatically get a filter file.

This patch adds the code to implement the filter logic in the trace
recordings.
