Implement bailout outside of the dive planner

Browse source 
This is the second step for implementing bailout. The indirect
calls to fill_pressures through add_segment() (in deco.c) are
addressed. Bailout is now fully implemented in the dive log but
not in the dive planner.
1) The parameters to add_segment() are changed to take a
   divemode as the second last parameter, and not a *dive.
2) Call to add_segment() in profile.c and in divelist.c are
   adapted. In divelist.c some calls to add_segment were left
   using dc-> divemode instead of possible bailout. This appears
   tp be the most appropriate route.
3) The functions get_divemode_from_time() and get_next_divemodechange()
   in dive.c have had some small changes.
4) The calls to get_segment(0 in planner.c were changed to reflect
   the new parameter list, but not updated to reflect bailout. This
   is the next step.
