Allocate dive samples separately from 'struct dive'

Browse source 
We used to avoid some extra allocations by just allocating the dive
samples as part of the 'struct dive' allocation itself, but that ends up
complicating things, and will make it impossible to have multiple
different sets of samples (for multiple dive computers).

So stop doing it. Just allocate the dive samples array separately.
