commit 828587944cbc5854b414f98bcd0bc5181f87825e
Author: Tamas K Lengyel <tamas.lengyel@xxxxxxxxxxxx>

monitor: rename and relocate vm_event_monitor_traps
The function vm_event_monitor_traps actually belongs in the monitor
subsystem.
As part of this patch we fix the sync input's type to bool_t to match how
the callers use it.
