Try to sanely download multiple concurrent cylinder pressures
This tries to sanely handle the case of a dive computer reporting
multiple cylinder pressures concurrently.
NOTE! There are various "interesting" situations that this whole issue
brings up:
- some dive computers may report more cylinder pressures than we have
slots for.
Currently we will drop such pressures on the floor if they come for
the same sample, but if they end up being spread across multiple
samples we will end up re-using the slots with different sensor
indexes.
That kind of slot re-use may or may not end up confusing other
subsurface logic - for example, make things believe there was a
cylidner change event.
- some dive computers might send only one sample at a time, but switch
*which* sample they send on a gas switch event. If they also report
the correct sensor number, we'll now start reporting that pressure in
the second slot.
This should all be fine, and is the RightThing(tm) to do, but is
different from what we used to do when we only ever used a single
slot.
- When people actually use multiple sensors, our old save format will
start to need fixing. Right now our save format comes from the CCR
model where the second sensor was always the Oxygen sensor.
We save that pressure fine (except we save it as "o2pressure" - just
an odd historical naming artifact), but we do *not* save the actual
sensor index, because in our traditional format that was always
implicit in the data ("it's the oxygen cylinder").
so while this code hopefully makes our libdivecomputer download do the
right thing, there *will* be further fallout from having multiple
cylinder pressure sensors. We're not done yet.

Improve profile display in planner
This patch allows the planner to save the last manually-entered
dive planner point of a dive plan. When the plan has been saved
and re-opened for edit, the time of the last-entered dive planner
point is used to ensure that dive planning continues from the same
point in the profile as was when the original dive plan was saved.
Mechanism:
1) In dive.h, create a new dc attribute dc->last_manual_time
with data type of duration_t.
2) In diveplanner.c, ensure that the last manually-entered
dive planner point is saved in dc->last_manual_time.
3) In save-xml.c, create a new XML attribute for the <divecomputer>
element, named last-manual-time. For dive plans, the element would
now look like:
<divecomputer model='planned dive' last-manual-time='31:17 min'>
4) In parse-xml.c, insert code that recognises the last-manual-time
XML attribute, reads the time value and assigns this time to
dc->last_manual_time.
5) In diveplannermodel.cpp, method DiveplannerPointModel::loadfromdive,
insert code that sets the appropriate boolean value to dp->entered
by comparing newtime (i.e. time of dp) with dc->last_manual_time.
6) Diveplannermodel.cpp also accepts profile data from normal dives in
the dive log, whether hand-entered or loaded from dive computer. It
looks like the reduction of dive points for dives with >100 points
continues to work ok.
The result is that when a dive plan is saved with manually entered
points up to e.g. 10 minutes into the dive, it can be re-opened for edit
in the dive planner and the planner re-creates the plan with manually
entered points up to 10 minutes. The rest of the points are "soft"
points, shaped by the deco calculations of the planner.
Improvements: Improve code for profile display in dive planner
This responds to #1052.
Change load-git.c and save-git.c so that the last-manual-time is
also saved in the git-format dive log.
Several stylistic changes in text for consistent C source code.
Improvement of dive planner profile display:
Do some simplification of my alterations to diveplannermodel.cpp
Two small style changes in planner.c and diveplannermodel.cpp

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.

Undo: fix multi-level undo of delete-dive and remove-dive-from-trip
The original undo-code was fundamentally broken. Not only did it leak
resources (copied trips were never freed), it also kept references
to trips or dives that could be changed by other commands. Thus,
anything more than a single undo could lead to crashes.
Two ways of fixing this were considered
1) Don't store pointers, but unique dive-ids and trip-ids.
Whereas such unique ids exist for dives, they would have to be
implemented for trips.
2) Don't free objects in the backend.
Instead, take ownership of deleted objects in the undo-object.
Thus, all references in previous undo-objects are guaranteed to
still exist (unless the objects are deleted elsewhere).
After some contemplation, the second method was chosen, because
it is significantly less intrusive. While touching the undo-objects,
clearly separate backend from ui-code, such that they can ultimately
be reused for mobile.
Note that if other parts of the code delete dives, crashes can still
be provoked. Notable examples are split/merge dives. These will have
to be fixed later. Nevertheless, the new code is a significant
improvement over the old state.
While touching the code, implement proper translation string based
on Qt's plural-feature (using %n).

Undo: select dives after add, remove, merge, split dive commands
Select the proper dives after the add, remove, split and merge
dives commands on undo *and* redo. Generally, select the added
dives. For undo of add, remember the pre-addition selection.
For redo of remove, select the closest dive to the first removed
dive.
The biggest part of the commit is the signal-interface between
the dive commands and the dive-list model and dive-list view.
This is done in two steps:
1) To the DiveTripModel in batches of trips. The dive trip model
transforms the dives into indices.
2) To the DiveListView. The DiveListView has to translate the
DiveTripModel indexes to actual indexes via its QSortFilterProxy-
model.
For code-reuse, derive all divelist-changing commands from a new base-class,
which has a flag that describes whether the divelist changed. The helper
functions which add and remove dives are made members of the base class and
set the flag is a selected dive is added or removed.
To properly detect when the current dive was deleted it
became necessary to turn the current dive from an index
to a pointer, because indices are not stable.
Unfortunately, in some cases an index was expected and these
places now have to transform the dive into an index. These
should be converted in due course.

First step in cleaning up cylinder pressure sensor logic
This clarifies/changes the meaning of our "cylinderindex" entry in our
samples. It has been rather confused, because different dive computers
have done things differently, and the naming really hasn't helped.
There are two totally different - and independent - cylinder "indexes":
- the pressure sensor index, which indicates which cylinder the sensor
data is from.
- the "active cylinder" index, which indicates which cylinder we actually
breathe from.
These two values really are totally independent, and have nothing
what-so-ever to do with each other. The sensor index may well be fixed:
many dive computers only support a single pressure sensor (whether
wireless or wired), and the sensor index is thus always zero.
Other dive computers may support multiple pressure sensors, and the gas
switch event may - or may not - indicate that the sensor changed too. A
dive computer might give the sensor data for *all* cylinders it can read,
regardless of which one is the one we're actively breathing. In fact, some
dive computers might give sensor data for not just *your* cylinder, but
your buddies.
This patch renames "cylinderindex" in the samples as "sensor", making it
quite clear that it's about which sensor index the pressure data in the
sample is about.
The way we figure out which is the currently active gas is with an
explicit has change event. If a computer (like the Uemis Zurich) joins the
two concepts together, then a sensor change should also create a gas
switch event. This patch also changes the Uemis importer to do that.
Finally, it should be noted that the plot info works totally separately
from the sample data, and is about what we actually *display*, not about
the sample pressures etc. In the plot info, the "cylinderindex" does in
fact mean the currently active cylinder, and while it is initially set to
match the sensor information from the samples, we then walk the gas change
events and fix it up - and if the active cylinder differs from the sensor
cylinder, we clear the sensor data.
[Dirk Hohndel: this conflicted with some of my recent changes - I think
I merged things correctly...]

Add "get_gasmix()" helper function to iterate over gas changes
We have a few places that used to get the gasmix by looking at the
sensor index in the plot data, which really doesn't work any more.
To make it easier for those users to convert to the new world order,
this adds a "get_gasmix()" function. The gasmix function takes as its
argument the dive, the dive computer, and the time.
In addition, for good performance (to avoid looping over the event list
over and over and over again) it maintains a pointer to the next gas
switch event, and the previous gas. Those need to be initialized to
NULL by the caller, so the standard use-case pattern basically looks
like this:
struct gasmix *gasmix = NULL;
struct event *ev = NULL;
loop over samples or plot events in increasing time order: {
...
gasmix = get_gasmix(dive, dc, time, &ev, gasmix);
...
}
and then you can see what the currently breathing gas is at that time.
If for some reason you need to walk backwards in time, you can just pass
in a NULL gasmix again, which will reset the event iterator (at the cost
of now having to walk all the events again).
