Modified Files:
        src/sys/dev/sysmon: sysmon_envsys.c sysmon_envsys_events.c sysmonvar.h

Log Message:
Improve tracking of the state of an event's callout, and protect all
queries or modifications of the state with the sme_mtx mutex.

Detach the rndsrc before re-attaching it (with potentially new values).

Clean up some lock-ordering issues.

And a couple of KNF issues for good measure!

Should address PR kern/52533
