The event names were registered in add_event(). However,
the undo system did not use that function, but add_event_to_dc(),
which takes an already allocated event.
That gave the following unfortunate situation:
Load a log without setpoint changes.
Add a setpoint change.
The setpoint change event type now was not registered and
therefore couldn't be hidden.
Admittedly, a subtle bug, but still a bug. Fix by registering
event names on event creation.

The eventname handling code was splattered all over the place.
Collect it in a single source file and use C++ idioms to avoid
nasty memory management. Provide a C-only interface, however.

In an effort to reduce the size of dive.h and dive.c, break out
the event related functions. Moreover event-names were handled
by the profile-code, collect that also in the new source files.
