In commit 0d7c192e6e ("For CCR dives, the diluent cylinder is the
current cylinder") a few things got broken. This tries to undo those
changes and adds expanded XML output.
1) Calculate correct partial pressure of oxygen to be plotted on
dive profile, taking into account the oxygen sensor data.
Currently, erroneously, OC PO2 values are shown, due to an
erroneous calling parameter to fill_pressures().
2) Read start and end cylinder pressured correctly. some wrong
assignments were done in file.c. This is now corrected and the correct
cylinder pressures are shown in the equipment tab.
3) Write correct cylinder pressures to XML. Currently the data for
the two cylinders are written to XML the wrong way round
(diluent pressures = oxygen and vice versa).
4) Expand XML output:
a) Write oxygen sensor data to XML
b) Write no_of_02sensors to XML

In a test case loading dives/test35.xml results in a infinite(-like)
loop (Note: possibly requires the partial pressure plots enabled).
calculate_gas_information_new() has an 'if' branch to
update the cylinderindex to a dive's diluent_cylinder_index,
but it does not consider that said index can be set previously
to -1.
This results in a random neighbour memory assigned as
&dive->cylinder[-1].gasmix and passed to fill_pressures(..).
Following the calculations in the function the He gas,
can receive a bad value (e.g. for the test case in the
E+6 ranges).
Said value is then used in DivePlotDataModel()::pheMax()
(defined by MAX_PPGAS_FUNC()) resulting in one of the loops
(the 3rd one) in DiveCartesianAxis::updateTicks() to
loop indefinitely.

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

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.

that forms part of plot_info.
