Currently the event type code uses libdivecomputer's flags
to differentiate between events. Make this explicit and extract
the event severity.
The reason is that later we want to be more explicit about showing/
hiding events and thereto we must format the name of events.
Moreover, this encapsulates the complexities of extracting
the severity in the event code (that used to be in the profile
code).

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.
