events: Rename TRACE_EVENT_TEMPLATE() to DECLARE_EVENT_CLASS()
It is not quite obvious at first sight what TRACE_EVENT_TEMPLATE
does: does it define an event as well beyond defining a template?
To clarify this, rename it to DECLARE_EVENT_CLASS, which follows
the various 'DECLARE_*()' idioms we already have in the kernel:
DECLARE_EVENT_CLASS(class)
DEFINE_EVENT(class, event1)
DEFINE_EVENT(class, event2)
DEFINE_EVENT(class, event3)
To complete this logic we should also rename TRACE_EVENT() to:
DEFINE_SINGLE_EVENT(single_event)
... but in a more quiet moment of the kernel cycle.
