Incorporate bailout events in CCR & PSCR gas calculations.

This is a first step to interpret bailout events.
1) The event structures have a new attribute: divemode.
   Currently interpreted dive modes are OC, CCR, PSCR.
2) When doing fill_pressures(), the calculation is aware
   of divemode. When divemode is OC (==bailout), then
   the appropriate calculations of gas pressures are done.
3) Two new functions get_next_divemodechange() and
   get_divemode_at_time() are created to find divemode
   changes in the events linked list and to determine
   the dive mode at any point during the dive.
4) fill_pressures gets a small amendment to facilitate
   the correct calculations, depending on divemode.
The cases where fill_pressures() is used *outside the planner*
are changed. The result is that, for dives with bailout, the
correct gas pressures are shown on the dive profile. The
deco for bailout dives is not yet correct. This is the
next step.
