The logic for when to output a gasmix in the notes table is more
complicated than it seems at first.
- On a descent leg, the gas is the gas used for descent
- At a stop (calculated or user defined), the gas is the gas used for that
stop
- But on an ascent leg (if displayed), the gas is the gas that is ABOUT TO
BE USED
- The gas should not be repeated if it's the same gas as used on the last
row of the table
- Ascent legs should only be displayed if the display transitions option
is selected, OR if there is a gas change without a stop (the user can
now set a minimum duration for a gaschange, but zero is still allowed).
The existing code tries to track what gas is being used/switched to at
each waypoint, and whether the gas should be printed or postponed to the
next leg. It works sometimes but not always.
This patch replaces the postponed gas logic with:
- Is this an ascent leg? (determines whether the applicable gas is the
preceding or following leg, and whether the leg should be displayed at
all if the transitions option isn't selected)
- Is it an ascent with a gaschange without a stop?
- Has the gas actually changed from the last output?
- Will the next leg be at the same level and same gas (in which case merge
them)?

Change the timestep used to calculate tissue pressures and ascents from 3
seconds to 2 seconds. But whats wrong with using 3 seconds?
Deco stops are at 3 m (10') intervals, and our ascent rate is usually
9 m/min (30'/min), or at least multiples of 3 m/min (10'/min). Hence time
to ascend from one stop to the next stop is 20s (or any factor of 60).
Using 3s increments, we round our ascent interval up to 21 s, which leads
to messy durations and runtimes.
But what about me? I like SI units and whole decimals. Don't worry, 2s
timesteps fit nicely when using 10 m/min ascent rate (18 s between stops).

This adopts the planner to the needs of the recreational diver. Rather than immediately
starting to ascent doing deco stops this mode, this mode stays at the last manually

change gas but keeps using the last used cylinder.

In the decision if a dive segment should lead to a line in the
diveplan, we need to differentiate between the lastdepth (the
depth of the last dp to tell if we are currently stopping) and
the last depth that we printed a line for (needed for gaschange
lines). Without this patch, no stops without gas changes were
listed anymore in the diveplan.
Like the last patch for the diveplan: I hope this time I got this
logic right.

This is a pain. We plan with segments but the plan shows waypoints.
If after a constant depth segment the gaschange (or setpoint chenge
for that matter) appears, the _next_ line should get the info
about the new gas (i.e. change _after_ the constant depth segment).
If, however, the gas is changed after a transition, the final waypoint
of the transition gets the gas printed.
And all is different for a verbatim plan, where the gas change is
an event rather than part of a segment.

Calculations for passive semi-closed rebreathers are pretty much like OC
except the pO2 is lower bey a certain (SAC dependent) factor. This patch
introduces the corresponding calculations in case dctype == PSCR which is
so far never set and there is currently no UI for these calculations. As
pO2 is SAC dependent it takes a certain attempt at getting it and drops to
defaults from the prefs otherwise.
As there is no UI at this point and I also don't have any dives, this has
not received much testing, yet, but it compiles. At least.

With this information, when we re-plan a dive we can bring the user right
back to the point where they ended - they have the waypoints in the dive
pointes table and handles are shown on the right points in the profile -
and the rest of the dive is once again calculated by the planning
algorithm.
For now this state is lost when saving the dive file as we don't add this
flag in the sample to our saved files. So if we don't find any samples
marked as manually added we add ALL of the samples as way points on the
diveplan and the user has to manually remove the ones that were
calculated.

there was a tiny red line at depth 0 in the planned profile. Turns out
that was the missing mean depth. We didn't populate enough data in the

instead of the duration stored in the dive computer).

Before this function was changed it was really supposed to just change a
gas that was passed in in case there was an event that changed the mix -
but with the new name the caller will assume that they get a valid gasmix.
And promptly we had one caller that didn't initialize gas to be based on
the first cylinder before calling get_gas_at_time().
Instead of adding yet one more spot that knows about the oddity of the old
API I simply changed get_gas_at_time() to do what it name appears to imply
and fixed the other callers not to bother to initialize the gasmix.

In add_plan_to_notes(), call update_cylinder_related_info() to compute
CNS and OTU data for the planned dive. Report their values in the notes.
Besides CNS and OTU, update_cylinder_related_info() also recomputes the
SAC, which is harmless. Note that both dive->cns and dive->maxcns need
to be zeroed out for the CNS value to actually be recomputed.

Add dive mostly works - when the user clicks save the dive is added to the

Plan dive is mostly untested. It passed trivial "start planner, save"
