Log Message:
netbsd-lldb: Add to the NetBSD Process Ponitor code support for new events

Add code to recognize:
 - TRAP_CHLD and FORK, VFORK, VFORK_DONE
 - TRAP_LWP and LWP_CREATE, LWP_EXIT
 - TRAP_HWWPT

This code recognizes (however still does not do much beyond it) all the needed
events in MonitorCallback function in the NetBSD Process Plugin.
