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,
replace the passInData function by a role to setData(). Secondly,
read the working-pressure and size via new columns using data().

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.

Instead of accessing the cylinder table directly, use the get_cylinder()
function. This gives less unwieldy expressions. But more importantly,
the function does bound checking. This is crucial for now as the code
hasn't be properly audited since the change to arbitrarily sized
cylinder tables. Accesses of invalid cylinder indexes may lead to
silent data-corruption that is sometimes not even noticed by
valgrind. Returning NULL instead of an invalid pointer will make

Instead of using fixed size arrays, use a new cylinder_table structure.
The code copies the weightsystem code, but is significantly more complex
because cylinders are such an integral part of the core.
Two functions to access the cylinders were added:
get_cylinder() and get_or_create_cylinder()
The former does a simple array access and supposes that the cylinder
exists. The latter is used by the parser(s) and if a cylinder with
the given id does not exist, cylinders up to that id are generated.
One point will make C programmers cringe: the cylinder structure is
passed by value. This is due to the way the table-macros work. A
refactoring of the table macros is planned. It has to be noted that
the size of a cylinder_t is 64 bytes, i.e. 8 long words on a 64-bit
architecture, so passing on the stack is probably not even significantly
slower than passing as reference.

The fill_default_cylinder() function calculated the MOD based
on the currently displayed dive. This does not seem to make sense:
- When importing dives, why would we care about the altitude and
salinity of the currently displayed dive, possibly from a different
trip.
- The planner is supposed to be thread-safe and should not touch
global variables.
Of course this means that the importing-functions have to fill
out altitude and salinity before creating the default cylinder,
but this is their problem. For a freshly created dive they will
get the default values, which still seems less random than the
values from the displayed dive.

Since the default view is batched by trips, signals were sent trip-wise.
This seemed like a good idea at first, but when more and more parts used
these signals, it became a burden. Therefore push the batching to the
part of the code where it is needed: the trip view.
The divesAdded and divesDeleted are not yet converted, because these
are combined with trip addition/deletion. This should also be detangled,
but not now.

dive-list model now does its own sorting. This will have to be

In a previous commit, the get_gasmix_* functions were changed to
return by value. For consistency, also pass gasmix by value.
Note that on common 64-bit platforms struct gasmix is the size

same space on the stack. On 32-bit platforms, the stack use

This is really unrelated to my recent "multiple gas pressures" work, but
the test case from Gaetan Bisson showed that the logic for which
cylinders to show in the equipment tab was less than optimal.
We basically used to show only cylinders that were actively used, unless
you had the "display_unused_tanks" preference option set. That comes
from some dive computers reporting a *lot* of cylinders that the diver
really doesn't even have with him on the dive. And showing those extra
dummy cylinders gets pretty annoying after a time, which is why we
default to not showing unused tanks.
However, in Gaetan's case, he had a total of four cylinders on the dive:
the O2 and diluent bottle for the rebreather dive, and then bailout
bottles (both air and deco). And while the bailout bottles weren't
actually used, Gaetan had actually filled in all the pressure details
etc for them, and so you'd really expect them to show up. These were
*not* just some extraneous default cylinder filled in by an over-eager
dive computer.
But because the bailout wasn't used, the manual pressures at the end
were the same as at the beginning, and the "unused cylinder" logic
triggered anyway.
So tweak the logic a bit, and say that you show cylinder equipment not
only if it has been used on the dive, but also if it has any pressure
information for it.
So the o nly cylinders we don't show are the ones that really have no
interesting information at all, except for possibly the cylinder tank
type itself (which is exactly what the over-eager dive computer case
might fill in, usually in the form of a default cylinder type).

This reverts commit adaeb506b7.
commit a8e8d56ec0 ("Tweak cylinder equipment tooltips") does a much
better job allowing the user to know the true volume of the cylinder
(given the gas entered) and clutters the UI a lot less.
While playing around with the current subsurface, I realized that while we
give the gas volume and Z factor for the beginning/end pressures in the
newly added tooltips, there is no way to actually see that same
information for the working pressure.
So if you have filled in cylinder type information, but don't have any
actual gas usage information, there will be no cylinder tooltips at all.
But you might still want to know what the actual volume for a particular
cylinder is, and what the Z value for that working pressure is.
So this tweaks the tool-tips a bit.
When mousing over the pressure fields (ie "working pressure", "start" and
"end"), it now always gives the cylinder gas volume and Z factor for that
pressure, so for example on an AL72 that has a working pressure of 3000
psi and that contains air the tooltip will say:
69 cuft, Z=1.040
when you mouse over the working pressure field (that's obviously with
imperial units, in metric you'll see liters of gas).
When mousing over the type/size field, it gives the used gas amounts, ie
something like this:
37 cuft (82 cuft -> 45 cuft)
but if the cylinder doesn't have starting/ending pressures (and thus no
used gas information), this patch will make subsurface show the working
pressure data instead, so that you at least get something.
This all seems more useful than what my first version gave.
NOTE! This makes commit adaeb506b7 ("Show both the nominal and "real"
size for an imperial cylinder") kind of pointless. You now see the real
size in the tooltip when you mouse over the size, and now it actually
works both for imperial and metric people, so the tooltip is in many ways
the better model.

This adds tooltips for the equipment tab for each cylinder, showing the
amount of gas used.
When you mouse over the size and working pressure fields, the tooltip will
show the amount of gas used (along with start and end gas volumes). And
when you mouse over the start and end pressures, it will show the start
and end gas volumes, and the Z factor used.
I started doing this because of the gas volume questions in the last day
or two (and a few from a few weeks ago). When even Robert Helling starts
wondering about the effects of compressibility on the SAC calculation, our
numbers are clearly too opaque.
With these tooltips, at least you can see what went into the used gas
calculations, instead of having to add debugging options to print out Z
factors.

We had two totally different usage cases for "get_volume_string()": one
that did the obvious "show this volume as a string", and one that tried
to show a cylinder size.
The function used a magic third argument (the working pressure of the
cylinder) to distinguish between the two cases, but it still got it
wrong.
A metric cylinder doesn't necessarily have a working pressure at all,
and the size is a wet size in liters. We'd pass in zero as the working
pressure, and if the volume units were set to cubic feet, the logic in
"get_volume_string()" would happily convert the metric wet size into the
wet size in cubic feet.
But that's completely wrong. An imperial cylinder size simply isn't a
wet size. If you don't have a working pressure, you cannot convert the
cylinder size to cubic feet. End of story.
So instead of having "get_volume_string()" have magical behavior
depending on working pressure, and getting it wrong anyway, just make
get_volume_string do a pure volume conversion, and create a whole new
function for showing the size of a cylinder.
Now, if the cylinder doesn't have a working pressure, we just show the
metric size, even if the user had asked for cubic feet.
