06ddfc0122 Prepare for PSCR calculations
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.

40bdd607c0 Calculate nitrogen and helium gas pressures for CCR after import from CSV
Currently the gas pressures stored in structures of pressure are
calculated using the gasmix composition of the currently selected
cylinder. But with CCR dives the default cylinder is the oxygen
cylinder (here, index 0). However, the gas pressures need to
be calculated using gasmix data from cylinder 1 (the diluent
cylinder). This patch allows setting the appropriate cylinder
for calculating the values in the structures of pressure. It
also allows for correctly calculating gas pressures for any
open circuit cylinders (e.g. bailout) that a CCR diver may
use. This is performed as follows:

1) In dive.h create an enum variable {oxygen, diluent, bailout}

2) Within the definition of cylinder_t, add a member: cylinder_use_type
   This stores an enum variable, one of the above.

3) In file.c where the Poseidon CSV data are read in, assign
   the appropriate enum values to each of the cylinders.

4) Within the definition of structure dive, add two members:
   int oxygen_cylinder_index
   int diluent_cylinder_index
   This will keep the indices of the two main CCR cylinders.

5) In dive.c create a function get_cylinder_use(). This scans the
   cylinders for that dive, looking for a cylinder that has a
   particular cylinder_use_type and returns that cylinder index.

6) In dive.c create a function fixup_cylinder_use() that stores the
   indices of the oxygen and diluent cylinders in the variables
   dive->oxygen_cylinder_index and dive->diluent_cylinder_index,
   making use of the function in 4) above.

7) In profile.c, modify function calculate_gas_information_new()
   to use the above functions for CCR dives to find the oxygen and
   diluent cylinders and to calculate partail gas pressures based
   on the diluent cylinder gas mix.

This results in the correct calculation of gas partial pressures
in the case of CCR dives, displaying the correct partial pressure
graphs in the dive profile widget.

6cf3787a0e Remove code that zeroes out duplicate oxygen sensor and temperature values
Remove the code that changes all duplicate oxygen sensor, setpoint and
temperature values from a dive log to zero. One of the motivations is
that a zero setpoint value indicates an Open Circuit dive segment, not
Closed Circuit Rebreather. The code in dive.c is removed and the comments
for the corresponding restoration code that restores the last known values
into sensor or temperature with zero values is [fill_o2_values()
in profile.c] is changed to apply to the present situation.

9e2ce3d99a Remove code causing problems with CCR dive log rendering.
Currently, if there is a po2 given in the dive log, the dive is assumed
to be CCR. When a CCR dive has a fo2 of 100%, then the po2 is set as
the same as ambient pressure. This destroys the CCR po2 graph in the dive
profile that derives from oxygen with a fo2 of 100% in one of the
cylinders but which, after adding the dilent gas, has a po2 far below
ambient pressure. The calculation for 100% oxygen only applies to deco
using 100% o2 and then the dive computer calculates the appropriate po2.
This patch removes the setting of po2 to ambient when fo2 is 100%,
1) to enable accurate graphing of po2 values for CCR dives using 100% o2
   in the first cylinder.
2) To use the po2 value reported by the DC in the first place.

e32ba4d6d8 Improve tank handling for Cobalt
This isn't Cobalt specific, this is specific to dive computers that
indicate the first tank that's in use with a gaschange event that
coincides with the first sample.

We need to make sure that we suppress showing that gas change event
(regardless which cylinder it goes to) and instead set the correct
cylinder index from the very start of the dive.

This works with the test data I have and doesn't seem to break thing with
any of the files that I tried... but I'm worried that this is not the
right way to do things.

5f44fdd9cf Make planner work again for CCR dives
The latest CCR patches had rendered the planner not usable for CCR dives.
This patch corrects this (and reenables the CCR set point column for
segments). The problem was that a new member setpoint of struct divepoint
had been introduced, but there was already po2 which had the same meaning.
This patch merges the two and renames them setpoint to prevent future
confusion.

c8eb2dccc5 CCR patch: Reorganise the oxygen partial pressure calculations
This patch responds to the side effects that the CCR code has had with
respect to ceilings in OC dives and dive plans. Dive ceilings are now
calculated correctly again.

The following were performed:
1) remove the oxygen sensor and setpoint fields from the gas_pressures
   structure.
2) Re-insert setpoint and oxygen sensor fields in the plot_data structure.
3) Remove the algorithm that reads the o2 sensor data and calculates the
   pressures.po2 value from function fill_pressures() in dive.c and save
   it as a separate function calc_ccr_po2() in profile.c.
4) Activate calc_ccr_po2 from function fill_pressures() in profile.c.
5) Move the relative position of the call to fill_pressures() within the
   function create_polt_info_new() in profile.c.

bc9df4652f CCR patch: Calculate the correct partial gas pressures for CCR dives
This patch adds code to the function fillpressures() in dive.c to
allow calculating o2 pressures, based on the data from the po2
sensors in the system. The following changes were made:
1) add code to perform po2 calculations for CCR with 1, 2 or 3
   oxygen sesnors.
2) Add four fields to the gas_pressures structure in dive.h. This
   allows communication of data between the function that calls
   get_pressures() and the return of partail pressure values to the
   calling function.
3) Delete the fields for setpoint and gas partial pressures from
   the structure plot_info. All partial pressures (from instruments
   as well as calculated) now reside in the pressures structure
   that forms part of plot_info.
4) Perform changes in several parts of profile.c to make use of the
   pressures structure in plot_info.

49c9ad199f CCR patch: Oxygen partial pressures
This patch does three things:
1) A new function fill_o2_values() is added to profile.c. This
   fills all oxygen sesnsor and setpoint values that have been
   zeroed before in order to save space in the dive log. This
   recreates the full set of sensor values obtained from the
   original CCR xml log file.
2) Function fill_o2_values() is activated in function create_
   plot_info_new() in profile.c
3) The calling parameters to function fill_pressures() in dive.c
   are changed. The last parameter is now a pointer to a structure
   of divecomputer. This will be needed in the last patch of the
   present series of three patches.

5b14ed16ac Add "download into private trip" dialog checkmark
This adds a checkbox for the divecomputer download dialog that allows you
to tell the download to put the newly downloaded dives into a trip of
their own. That in turn will disable the dive merging with any existing
dives, which means that you will not mix up your newly downloaded dives
with any old dives.

That, in turn, is very convenient of you know that some of the dives were
done by other divers (or from testing that happened during servicing etc),
or the dive dates etc were wrong because the dive computer date had reset
due to battery changes etc.

Once you have all the dives in a private trip of their own, you can then
fix them up (delete dives you don't want to merge etc), and then after all
the data is ok you might want to merge the cleaned-up results with
previous trips etc, and then manually ask subsurface to merge the dives or
whatever.

ecf0408aae Make SAC values in planner settings respect unit settings
So far, the fields for the two SAC rates did not show a unit and were implictly l/min.
Now they respect the settings for volume units. This was harder than I thought for two reasons:

1) Imperial units for SAC are cuft/min but a typical value would be .70. So I made the point
the field prefix and what is entered is actually hundreth of cuft per minute.

2) I had to get the rounding right in order not to get effects like 20l/min become .70 cuft/min (19800 ml/min
internally) which would then become 19l/min when switching back.

While being at it, I gave the gradient factors '%'-signs as units.

3aaf8b1f5a Make gas use statistics be coherent and more complete
The gas use logic in the dive statistics page is confused.

The SAC case had a special case for "unknown", but only for
the first gas. Other gases had the normal empty case.

Also, the logic was really odd - if you had gases that weren't used (or
pressures not known) intermixed with gases you *did* have pressure for,
the statistics got really confused.

The list of gases showed all gases that we know about during the dive,
but then the gas use and SAC-rate lists wouldn't necessarily match,
because the loops that computed those stopped after the first gas that
didn't have any pressure change.

To make things worse, the first cylinder was special-cased again, so it
all lined up for the single-cylinder case.

This makes all the cylinders act the same way, leaving unknown gas use
(and thus SAC) just empty for that gas.

It also fixes the SAC calculation case where we don't have real samples,
and the profile is a fake profile - possibly with gas changes in between
the fake points. We now make the SAC calculations match what we show -
which is admittedly not at all necessarily what the dive was, but at
least we're consistent.

74616cdddf Rename event: correctly replace event with new one
I don't like that the event structure includes the variable length array.
That really makes it a pain to change the name of an event (on the flip
side, freeing events is easier I guess).

Anyway, to correctly rename an event we need to actually remove the event
from the correct dc and then add a new event with the new name. The
previous code was insane (it only worked if the new name was of smaller or
equal length, otherwise it had a beautiful buffer overflow).

And of course we need to do this both for the current_dive and the

cd65c8512d UI restructure: add helper function to copy and clear a dive
This way we can safely copy around dives (specifically, copy the dive to
be displayed / edited into the displayed_dive).

a221a6e9f5 UI restructure: use a global variable to hold the dive we show / edit
There is massive confusion about what we display when and where and which
dive structure (or pointer to a dive structure) contains which information
at which stage. This is the first step towards restructuring all of this.

This creates a global variable displayed_dive which at any point in time
should be what is displayed on screen (both in the profile and in the
maintab). It removes the editedDive concept from MainTab.
