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
of a pointer [2 * 32 bit vs. 64 bit] and therefore uses the
same space on the stack. On 32-bit platforms, the stack use
is probably doubled, but in return a dereference is avoided.
Supporting arbitrary gas-mixes (H2, Ar, ...) will be such an
invasive change that going back to pointers is probably the
least of our worries.
This commit is a step in const-ifying input parameters (passing
by value is the ultimate way of signaling that the input parameter
will not be changed [unless there are references to said parameter]).

There were a handfull instances of the kind
1) gettextFromC::instance()->tr(...)
2) gettextFromC::instance()->trGettext(...)
1) is pointless, as tr is a static function.
All instances of 2) were likewise pointless, because trGettext()
returns a C-string, which was then immediately converted to a
QString.
Thus, replace both constructs by gettextFromC::tr(...).
After this change there was only one user of gettextFromC::instance()
left, viz. the C-interface funtion trGettext(). Therefore, remove
gettextFromC::instance() and do all the caching / translating
directly in the global trGettext().

were defined in qthelper.h. Therefore fold the former into the latter,
since the split seems completely arbitrary.

Replace constructs of the kind
s.toUtf8().data(),
s.toUtf8().constData(),
s.toLocal8Bit().data(),
s.toLocal8Bit.constData() or
qUtf8Printable(s)
by
qPrintable(s).
This is concise, consistent and - in principle - more performant than
the .data() versions.
Sadly, owing to a suboptimal implementation, qPrintable(s) currently
is a pessimization compared to s.toUtf8().data(). A fix is scheduled for
new Qt versions: https://codereview.qt-project.org/#/c/221331/

This changes the numeric format of many values printed to the UI to
reflect the correct numeric format of the selected locale:
- dot or comma as decimal separator
- comma or dot as thousands separator
In the Qt domain the `L` flag is used case specific mostly
in qthelper.cpp.
Then the helper functions get_xxx_string() are used more consistently.

Change the strategy when to allow cylinder removal from a dive:
- Not remove when cylinder has gas switch events, in any other cases
allow removal
- Remove this whole "cylinder with same gas" thing being a criteria
for cylinder removal
When removing a cylinder which has corresponding pressure info in
samples, also remove this pressure info from the samples.

There was a curious pattern of singletons being implemented based on

Planning dives is heavy on CPU, so better be sure we only
do it when needed. In particular, when moving around dive
points, we only want a new plan once per move and not three
times (triggered at various points in the chain of events).
This should significantly improve planner snappiness.

In the planner it is best practise to start the dive with the first
gas in the gaslist. Otherwise one would get a gaschange event at the
very beginning of a dive.
This change implements the following feature:
Automatically move a gas to position 0 in the gaslist if the user selects
this gas for the first dive data point.

In the planner if one adds two or more cylinders with the same gasmix
(e.g. back gas and bottom stage 18/45) the drop down and data in the
used gas column of the planner points table will be filled with a more
verbose string mentioning also the cyl number and the cyl type
description.
Makes it easier in such a case to select the right cylinder.
Introduces also a helper function which tells you if there is another
cylinder with the same gasmix as the provided cylinder.
This also has an option if it should consider unused cylinders or not.

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).

In the cylinder table, the last column ("use") always showed
OC-GAS. Editing was enabled, but the user had to guess to enter
a small integer meaning dilluent or CCR oxygen cylingder. I guess,
nobody has ever done that.
This patch makes this column clickable. A click toggles if the cylinder
is used for planning or not. This wait it is much easier to investigate
the consequences of gas loss on a plan.

This reverts commit adaeb506b7a1485cab741f12450abeb76e109276.
commit a8e8d56ec016 ("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 adaeb506b7a1 ("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.
[ This patch also adds a "rint()" to get the rounding right in the
gas_volume() function. Although rounding to the nearst milliliter
really doesn't matter, it's the right thing to do after doing FP
calculations ;^]

Adds fields to the planner cylinder model for maximum operating depth (MOD)
for a bottom mix gas, and maximum narcotic depth (MND). Fields are read/write,
so changing MOD changes %O2 and vice-versa. Changing MND changes %He and
vice-versa.
When setting MOD directly, the %O2 is truncated (rounded down) to an integer,
which re-calculates the MOD, which is sometimes a few metres greater than the
input depth. This is desireable behaviour, as the rounding is conservative.

Determining the correct cylinder index from a known gas mix can be
complicated, but it is trivial to look up the gasmix from the cylinder_t
structure.
It makes sense to remember which cylinder is being used. This simplifies
handling changing a cylinder's gas mix, either directly by the user, or
indirectly in the planner. It also permits tracking of multiple cylinders of
the same mix, e.g. independent twins / sidemount.
