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.

Added keeping bottom dive state and every deco's time, so we can
run multiple deco simulations with different gradients until they
converge to some optimal value.
Some improvements on the deco time calculation may be needed.

It improves (increases) gradients for all the compartments,
so more free gas can be created in the divers body. Next gradients
will converge, so the volume won't exceed the safe limit, indicated
by the crit_volume_lambda parameter.
Function takes time of the last deco in seconds.
Requires vpmb_start_gradient() to be run before.

This function calculates the size of nuclei at the end of deco,
then simulates their regeneration, to the moment before the deco.
This is redundant as nuclear regeneration is a very slow process.
Function should be called with time in seconds, just before the ascent.

For the values of b and c encounterd in the algorithm, the first solution is in fact the
only real one that we are after. So we can use this solution instead of doing a binary
search for the root of the cubic.

Remove several very noise messages on dive site handling (this seems to
work well now, so I think we can remove most of them - a couple were left
that indicate actual issues).
And also remove all the calls to "translate" when outputting data to
stderr. Error messages that indicate issues where the user will basically
have to come and ask the developers for help shouldn't be localized. They
should be in English to make it easier for us to figure out what's going
on.

There are a number of web servies we could use. All have their drawbacks.
This one is free with free data. It's daily limits are reasonably high.
For many coordinates I tested the results were good, for others at least
not terrible.
We can always consider supporting multiple such services. But for now this
seems like a reasonable choice.

When libdivecomputer switched to the DC_FIELD_TANK API it apparently
stopped creating fake pressure samples at the start and end of a dive for
dive computers that don't have continuous pressure reporting but that
instead only report those two values.
This updates our code to take those values into account.
