Libdivecomputer integration, part n+1

Browse source 
This actually gets me far enough that it prints out all the dives on my
dive computer.  It doesn't actually turn them into real dives yet,
though - only a series of ugly 'printf's so far.

And it hangs after printing the last dive. So I'm doing something wrong.
