We _really_ find the standard libdivecomputer event enumeration much too
inflexible and not giving us enough useful information. This is
particularly noticeable with the Suunto EON Steel/Core, where there are
no fixed event enumerations, but instead the dive computer literally
gives you event strings.
Do the same thing in the libdivecomputer interface: allow an event of
type SAMPLE_EVENT_STRING which instead of the useless "value" gives an
actual string describing the event.
Also, extend the "flags" field to have not just a NONE/BEGIN/END marker,
but a severity level. The severity level is 3 bits, so 0-7, with the meaning being
0 - 'no severity info'
1 - state change (so 'surface' event or similar - don't even show it by default)
2 - notification (informational, eg "safety stop", "tank change")
3 - warning ("ascent speed")
4 - alarm (some actual dive violation).
5-7: future expansion?
Think of 0 as "legacy - missing information", 1 as "internal DC thing",
and 2-4 as (green-yellow-red).
This makes it possible for the dive computer back-end to give the user
actual useful information for events.
