libtraceevent has added more levels of debug printout and with changes like: https://lore.kernel.org/linux-trace-devel/20210507095022.1079364-3-tz.stoyanov@xxxxxxxxx previously generated output like "registering plugin" is no longer displayed. This change makes it so that if perf's verbose debug output is enabled then the debug and info libtraceevent messages can be displayed. As this API isn't present in the deprecated tools version of libtracevent I'm uploading this as an RFC.
