2d8e343221 Planner: Improve Gas Handling in CCR Mode.
This has become a bit of a catch-all overhaul of a large portion of the
planner - I started out wanting to improve the CCR mode, but then as I
started pulling all the other threads that needed addressing started to
come with it.

Improve how the gas selection is handled when planning dives in CCR
mode, by making the type (OC / CCR) of segments dependent on the gas use
type that was set for the selected gas.
Add a preference to allow the user to chose to use OC gases as diluent,
in a similar fashion to the original implementation.
Hide gases that cannot be used in the currently selected dive mode in
all drop downs.
Include usage type in gas names if this is needed.
Hide columns and disable elements in the 'Dive planner points' table if
they can they can not be edited in the curently selected dive mode.
Visually identify gases and usage types that are not appropriate for the
currently selected dive mode.
Move the 'Dive mode' selection to the top of the planner view, to
accommodate the fact that this is a property of the dive and not a
planner setting.
Show a warning instead of the dive plan if the plan contains gases that
are not usable in the selected dive mode.
Fix the data entry for the setpoint in the 'Dive planner points' table.
Fix problems with enabling / disabling planner settings when switching
between dive modes.
Refactor some names to make them more appropriate for their current
usage.

One point that is still open is to hide gas usage graphs in the planner
profile if the gas isn't used for OC, as there is no way to meaningfully
interpolate such usage.

f120fecccb core: use std::vector<> to store divecomputer samples
This is a hairy one, because the sample code is rather tricky.

There was a pattern of looping through pairs of adjacent samples,
for interpolation purposes. Add an range adapter to generalize
such loops.

Removes the finish_sample() function: The code would call
prepare_sample() to start parsing of samples and then
finish_sample() to actuall add it. I.e. a kind of commit().

Since, with one exception, all users of prepare_sample()
called finish_sample() in all code paths, we might just add
the sample in the first place. The exception was sample_end()
in parse.cpp. This brings a small change: samples are now
added, even if they could only be parsed partially. I doubt
that this makes any difference, since it will only happen
for broken divelogs anyway.

408b31b6ce core: default initialize units-type objects to 0
Makes the code much nicer to read.

Default initialize cylinder_t to the empty cylinder.

This produces lots of warnings, because most structure are now
not PODs anymore and shouldn't be erased using memset().

These memset()s will be removed one-by-one and replaced by
proper constructors.

The whole ordeal made it necessary to add a constructor to
struct event. To simplify things the whole optimization of
the variable-size event names was removed. In upcoming commits
this will be replaced by std::string anyway.

801b5d50b2 core: replace dive_site::dives by an std::vector<>
Since this is now in C++, we don't have to use our crazy
TABLE_* macros.

This contains a logic change: the dives associated to a
dive site are now unsorted.

The old code was subtly buggy: dives were added in a sorted
manner, but when the dive was edited the list was not
resorted. Very unlikely that this leads to a serious
problem, still not good.

10fc3bfd47 Bugfix: Fix Incorrect Volumes Displayed for Tank Types.
Fix an issue introduced in #4148.
Essentially the refactoring missed the fact that in the imperial system
tank size is tracked as the free gas volume, but in the metric system
(which is the one used in most of Subsurface's calculations) tank size
is tracked as water capacity.
So when updating a tank template tracking imperial measurements, the
given (metric) volume in l has to be multiplied by the working pressure,
and vice versa.
This also combines all the logic dealing with `tank_info` data in one
place, hopefully making it less likely that this will be broken by
inconsistencies in the future.

Fixes #4239.

0d011231e6 desktop: unglobalize ComboBox-models
The combo-boxes (cylinder type, weightsystem, etc.) were controlled
by global models. Keeping these models up-to-date was very combersome
and buggy.

Create a new model everytime a combobox is opened. Ultimately it
might even be better to create a copy of the strings and switch
to simple QStringListModel. Set data in the core directly and
don't do this via the models.

The result is much simpler and easier to handle.

9f455b1457 selection: move current dive and divecomputer to selection.cpp
This tries to encapsulate the management of the current dive and
divecomputer in the selection code. The current dive is alreay
set by setSelection(). Add a new parameter to also set the
current divecomputer. If -1 is passed, then the current
computer number is remained. This will allow us to audit the code.
Because for now, the whole "current dive computer" thing seems
to be ill-defined.

This fixes a bug: the dive-computer number wasn't validated
when making a new dive the current dive. The new code has some
drawbacks though: when selecting a whole trip, the validation
will be called for all dives in the trip and thus the dive computer
number will depend on the dive with the lowest amount of dive
computers in the trip. This will need to be fixed.

1e3d378ad9 Cylindermodel: Improve editing of tank use
Use the drop down for editing the tank use in the gas list in both the
equipment tab and the dive planner.
The tank use column is now available in the equipment tab for all dives
and not just CCR dives, as 'not used' is a valid entry in both cases.
However, if the current dive is an OC dive, only 'OC-gas' and 'not used' are
shown.
There still seems to be a problem that in some cases, when opening the
planner after selecting an existing CCR dive the drop down in the
planner does not list CCR gas uses - for some reason `displayed_dive`
does not seem to be updated correctly on opening of the planner. But I have not been able to
reproduce this consistently, and changing 'Dive mode' fixes this.

27505aedfb cleanup: use pointer-to-member style connect for ComboBoxDelegate
This was still using the archaic macro version, because Qt decided
to parameter-overload the signals (which turned out to be a horrible
idea). However, since we switched to fairly recent Qt this can be
solved using the qOverload template.

In this case things are a bit more complicated because we overload
the corresponding slots. Since we have control over that, let's
just disambiguate their names instead of using the cryptic qOverload.

While doing this, tighten the access specifiers of the slots. Turn
public into private and protected as appropriate.

1dcc885bb2 undo/cylinders: Implement editing of the type
This one is tricky, as when browsing through the types-combobox,
the user is presented with presets without actually changing the
dive. We do not want an undo-command for every change-event in
the combo-box.

Therefore, implement a scheme analoguous to the weight-editing:
A temporary row can be set / committed or reset. Sadly, the
code is more complex because we have to consider the planner,
which is not included in the undo system.

Firstly, the planner uses a different model, therefore all
interactions are channeled through setData() with special roles.
Secondly, in the planner we shouldn't place an undo command,
but simply overwrite the dive.

fb76eb9a1a delegates: don't use starts-with search to fetch cylinder/weight data
In the wightsystem-type and cylinder-type delegates, when entering
data, when entering known weight- or cylinder-types, some ui fields
(notably weight, size and working-pressure) are automatically filled
out. The search was using the default flags provided by Qt: starts-with
and case-insensitive.

This had a few strange effects, when entering a string that is the
beginning of a known string (e.g. "AL6" when "AL63" already exists):

1) The wrong data was used if the new string didn't exist.
2) For cylinders it was impossible to create new cylinder types whose
   name is the starting string of a different type.
3) For weights, the new type was not added to the list of known types.
   This, however, is no problem, because it will be added by the undo
   command anyway. A future commit will address that redundancy.

Therefore use only the case-insensitive flag (which has to be performed
by passing the MatchFixedString flag - very weird).

cb80ff746b crash fix: Don't cast to CylindersModel or CylindersModelFiltered
The tank-info-delegate cast its model to CylindersModelFiltered,
since this is what the equipment-tab uses since implementing the
filtering of unused cylinders. However, the planner users the same
delegate and still uses the unfiltered CylindersModel. This means
that the (dynamic) cast returns a null pointer and crashes.

One possibility would be to derive CylindersModelFiltered and
CylindersModel from the same class that defines virtual functions
and cast to that class.

This is a different attempt: don't cast (i.e. stay with a
QAbstractItemModel and play it via Qt's model-view system. Firstly,

6622f42aab Cylinders: Add CylindersModelFiltered
When the show_unused_cylinders flag is not set, the cylinder tables
in the equipment tab and the planner should not show unused cylinders.
However, the code in CylindersModel is fundamentally broken if the
unused cylinders are not at the end of the list: The correct number
of cylinders is shown, but not the correct cylinders.

Therefore, add a higher-level CylindersModelFiltered model on top
of CylindersModel that does the actual filtering. Some calls are
routed through to the base model (notably those that take indexes,
as these have to be mapped), for some calls the caller has to get
access to the source model first. We might want to adjust this.

For filtering, reuse the already existing show_cylinder function
and export it via CylindersModel.

029c9ccf02 Desktop: refactor WSInfoDelegate logic
The WSInfoDelegate (weight-system-info delegate) is used to display
a combo box of known weightsystem-types and auto-fills the weight if
the weightsystem-type is changed.

This would overwrite the weight data of the displayed dive when the
user hovers over the different entries. Moreover, it saves the original
weight in case the user cancels the editing action.

This is not viable when implementing undo of weightsystem changes,
because hovering over entries should not produce individual undo
commands. Instead, implement a special "temporary" row in the
weightsystem model. On canceling of the edit actions, simply reload
the weightsystem from the unmodified dive.

992ad2fa27 Dive sites: simplify nr_of_dives_at_dive_site()
