Subject: [PATCH 1/2] Rename wait events with more consistent camelcase style

This will help in the introduction of more simplifications with the
generation of wait event data using wait_event_names.txt.  The event
names used the same case-insensitive characters, hence applying lower()
or upper() to the monitoring queries allows the detection of the same
events as before this change.
