This sets up a standard dive scenario (30 minutes at 260ft/79m, EAN36 and
Oxygen as deco gases, last stop at 20ft/6m) and calls the planner to set
up a dive plan given certain standard gases.
Instead of trying to verify the complete plans it checks that we switch to
the deco gases at the right depth and the complete duration of the dive
matches our expectation.
The test intentionally fails right now for imperial as we have the wrong
switch depth for Oxygen. See how useful tests are?
On the downside, the test does NOT produce the same plan as Subsurface
when I try to create a consistent setup for both - and I have not been
able to figure out why. There must be some other parameters that I'm not
setting, but I haven't identified them, yet. It's very small differences,
for example in the metric case the stops at 21m, 9m, and 6m are each one
minute shorter in the test than it what Subsurface calculates.

When using feet as depth unit, deco stop levels should be at 10 ft rather
than 3 m increments.
For shallow stops, rounding means the difference is not apparent. However,
with stops deeper than 30 feet, using 3 m increments leads stops at 39ft,
49ft, ..., 98ft, etc.
Apart from making plans look messy, the old behaviour makes it harder to
benchmark the planner against published profiles in imperial units.
This revised patch uses the help macro M_OR_FT(6, 20) to set the last stop
at the correct depth.

Read and use the last_stop preference in the plan function.
Read the plan notes preferences and set variables (plan_verbatim,
plan_display_runtime, plan_display_duration, and plan_display_transitions)
in the add_plan_to_notes function. Don't read the preferences and set
variables otherwise. Both plan and add_plan_to_notes functions are called
on data change.
Previous behaviour was:
- Set variables on declaration
- Reset variables in plan function (even variables that only relate to
planner notes output)
- Changing a preference triggered set_xxx function which sets variable,
then plan function, which sets variable again.
Apart from being inefficient, the previous behaviour made it difficult to
track down where and when variables were set.

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 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.

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

Before this function was changed it was really supposed to just change a

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
