Refactor timer merging and add it to CE plugin.

THIS CODE IS UNTESTED

We now initialize one event group for each cpu on system start. We can
get the event group for a CPU via a function in event_group.c

Another change is that an event now stores what group it is in when it
add_event() is called on it. This lets us cancel it without knowing what
event group it is in.

The above is important because Level-C events (like releases) have a
NULL event group. When calling add_event(), it will get the event group
of the current CPU. If the event needs to be canceled later, we need
that saved group in the event so we know where to remove it from.
