Cleanup: simplify dive_getUniqID()

Browse source 
dive_getUniqID() is used to create unique dive ids, which are
stable during application lifetime. It was passed a dive, checked
that the id was not set (if it was that it is know to the application)
and set a new id (in contradiction to its name!) if it hadn't any.

There were three callers:

alloc_dive(): called the function on a zeroed dive struct.
fixup_dive(): called the function only if the dive had a 0 id.
MainWindow::setupForAddAndPlan(): called the function on a zeroed dive
struct.

Thus, in all three callers the id is guaranteed to be zero and
the whole keeping-track-of-ids logic is moot. Remove the logic,
don't pass a dive struct to dive_getUniqID() and move the function
to the C-backend.
