Add helper to find the dive closest to a given time
If we want to keep the selected dive "close" to where it was before an
operation (whether a delete, or a reload, or something like that), then
the most intuitive thing to do appears to be to select either the same
dive again (if it still exists), or one very close to it in time. This
helper allows us to identify the dive in the current dive list that is
closest to the given time.
We do this in the C code to ensure that we look at all dives in the
dive_table - based on the id that is returned the UI can then figure out
where this dive is currently shown.
