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.

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.

This patch corrects this (and reenables the CCR set point column for

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.

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.

gaspressures.c. The following chnages were made:
1) dive.h: The function types of calculate_depth_to_mbar

2) profile.c: Prototypes for the functions in gaspressures.c
were inserted at the top of profile. Ten functions were
transferred from profile.c to gaspressures.c
3) gaspressures.c as well as a short header, gaspressures.h
were created.

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

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.

We were actually searching dives which match the dowloaded position
fixes. So we're also trying to take into account if the fix is automatic
or no based on a limited amount of predefined strings (bad idea, as the
user can change in companion app settings the predefined string).
This way, in actual implementation, if program concludes that a fix has
been manually got or, simply, the user is unlucky enough to have all the
position fixes out of the dive time, find_dive_n_near() function will
pair fix and dive in an ordered way (1st fix -> 1st dive; 2nd fix -> 2nd
dive ...) which is probably erroneous, except for manual position fixes.
BTW actual implementation can't pair the same gps position with more
than one dive, which would be the case, e.g. in repetitive dives while at
anchor in the same point.
The patch changes the logic:
- Search positions for defined dives (instead of dives for defined
positions) without care if position has manually or automatically been
set.
- Only take care of those dives that don't have a position yet.
- It makes two assumptions:
a.- If the position fix has been taken during the dive time, is
correct. If there are more than one inside the dive time, takes the
first one (closest to the DC's reported time).
b.- If not during diving time, the correct one is the nearest fix
before the dive begins (also the usual case if manually fixed from the
smartphone just before jump into the water). But will work too if there
is only one fix *in SAME_GROUP range* after the dive (another usual
case).
- Finally, as copy_gps_location() in dive.h is used only here, let it
take care of naming the dive if user hasn't named it yet.

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
displayed_dive.

automatically update the switch depth of all cylinders as those might have

Furthermore, MOD has now to option of rounding to multiples of a given

b) no_o2sensor (indicating number of o2 sensors for this dc)
3) In parse-xml.c add a function trimspace that strips any
whitespace from a string. This is used by two functions:
utf8_string as well as by get_dc_type, described below.
The pointer to buffer is not changed in order to ensure
consistency when the buffer is freed.
