This changes the divedatapoints and functions that deal with them.
It changes plan_add_segment(), create_dp(), gasToStr(), and tankInUse() to
consume gasmix instead of o2/he.

This is step one of many to use gasmix instead of int o2/he.
Right now some of these changes look ridiculous because after changing a
few lines we immediately go back to o2 = get_o2(gas). The reason is that I
wanted to convert a hand full of functions at a time. So in this commit I
only change validate_gas(), get_gas_from_events() and get_gasidx() to use
a struct gasmix instead of int o2, int he.
This state builds and survived some mild testing. Let's continue on top of
that.

We should never pass permille values around as integers. And we shouldn't
have to decode the stupid value in more than one place.
This doesn't tackle all the places where we access O2 and He "too early"
and should instead keep passing around a gaxmix. But it's a first step.

This part of the algorithm was off as part of it (but not all of it -
crazy, I know) assumed the old semantic for gas changes where the new gas
was introduced at the end of the segment and not at the beginning.

We tracked gas used by simulating a dive with a cylinder - but for that we
need a cylinder size and working pressure. If the user just enters a gas
but no cylinder data (likely in order to figure out how much gas is used
so that she then can pick a big enough cylinder), we didn't show any gas
consumption.
It kinda sucks to add another member to the cylinder structure, but this
seemed far more reasonable then some other, global structure that
independently tracks gas usage. This just seemed to make sense.

Gas switches are now for the current segment, not for the next.
We can only track gas for cylinders for which we have size / working
pressure information. Print a warning for others.
Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
If we have size information including working pressure for a cylinder, we
already track the expected pressure at each way point - this way we can
also alert the user if more gas is consumed than is available in the
cylinder.
This does not include sound planning strategies like "rule of thirds". It
simply assumes that you won't be able to breathe down the cylinder past
about 10bar (using 0 as cutoff seemed silly).

Silly bug - while we normally fill the cylinders in a tight group with no
"null" cylinders in the middle, since we copy from an existing dive and
since that may end up with an odd sequence of cylinders, we need to
continue looking at ALL cylinders and not stop with the first one that's
empty.

In analyze_gaslist() we were only keeping gases that had their .depth
above the current depth, i.e. where we could switch to in the future. Now
we take note as well of the strongest gas that we could have already
switched to and switch to it before we attempt to ascend.

This commit is a little bigger than I usually prefer, but it's all
somewhat interconnected.
- we pass around the cylinders throughout the planning process and as we
create the plan we calculate the gas consumption in every segment and
track this both in the end pressure of the cylinder and over time in
the samples
- because of that we no longer try to calculate the gas consumption after
being done planning; we just use what we calculated along the way
- we also no longer add gases during the planning process - all gases
have to come from the list of cylinders passed in (which makes sense
as we should only use those gases that the user added in the UI or
inherited from a the selected dive (when starting to plan with a dive
already selected)
With this patch I think we are close do being able to move all of the
planning logic back into the planner.c code where it belongs. The one
issue that still bothers me is that we are juggling so many dive
structures and then keep copying content around. It seems like we should
be able to reduce that.

In commit bcdd6192fe ("Show translated event names in tooltip") I was
too aggressive in replacing the checking for event names with checking for
event types. It turns out that we are abusing an existing event type in
the planner (and use a different event name to mark the difference). By
just checking for the type this now caused incorrect information to be
displayed in the info box (a simply "PO2 warning" on a Suunto D9 could
turn into a "Bailing out to OC" notice).
The correct fix is to get our own range of SAMPLE_EVENT_xxx numbers from
libdivecomputer. Once we have those, we can do this the right way. For now
we just fall back to also checking the event name (which is what I wanted
to get away from so translated names don't trip us up).
Signed-off-by: Dirk Hohndel <dirk@hohndel.org>
In order for this to work we need to compare against the event type
instead of the event name - which makes much more sense to do, anyway.

Rewrite of the actual planner logic. Now ascend to the next potential stop
depth. There the state is cached and we try to ascend to the next stop
depth. If we hit the ceiling while doing that we go back to the cached
state and wait there for a minute. Then we try again. Then loop.
Converted all depth related variables from unsigned int to int. During
planning, in a time step the current depth can temporarily be negative and
comparisons of a negative int with an unsigned it have not the result I
expected ( (int) -2 < (unsigned int) 3 turns out to be false). And we
don’t really need the 32nd bit that unsigned buys us for depths.
Deco stops are now shown in the same table as manually entered stops in
boldface (I removed the second table to save screen estate).
The gas shown in the table is still misleading as it means the gas used on
the segment leading up to that event.
The update of the profile only works partially upon changes in the list of
available gases.
Treatment of various gases is basically there but needs some more love.
The ascent velocity is now provided by a function that takes the current
depth as argument. Currently it always returns 10m/min but that will later
be variable (and hopefully user configurable).
The profile is not redrawn while deco is computed (avoiding an infinite
recursion).
The table got a new column for the duration of a segment while the old
“duration” column was renamed “Runtime” to reflect what it actually shows.
Currently, only the run time but not the duration are editable.
All deco gases are used from the depth where their pO2 is 1.4bar. This
should become more flexible.
Calculation of the pressure drop in cylinders without configured volumes
is suppressed. This solves a problem with the planner crashing when saving
a dive where not all cylinders had been manually given a volume.
[Short rant break: Treating 0/0 as air bites back at so many places. E.g.
Cylinder data is initialized with memsetting the whole structures to 0.
Then later suddenly this totally unconfigured cylinder is being treated as
it would contain air. Maybe at some point this was a feature. But it lead
to a naughty bug which took me over an hour to resolve. We should
seriously reconsider this choice and better move to 209/0 being air if
changing this everywhere is not too much trouble]

The "report_error()" interface is a lot simpler, although some of the
C++ code uses QStrings which make them a bit annoying, especially for
the varargs model. Still, even with the explicit conversion to UTF8 and
"char *", the report_error() model is much nicer.
This also just makes refreshDisplay() do the error reporting in the UI
automatically, so a number of error paths don't even have to worry. And
the multi-line model of error reporting means that it all automatically
does the right thing, and reports errors for each file rather than just
for the last file that failed to open.
So this removes closer to a hundred lines of cruft, while being a
simpler interface and doing better error reporting.

With this every cylinder downloaded from a divecomputer that doesn't
provide cylinder data, and every cylinder manually added anywhere will
default to the default cylinder that is set in the preferences.
For people who most of the time dive with the same equipment (always on
dive boats with AL80, or almost always diving their personal HP119) this
should be a nice improvement.
If you don't like this behavior, simply leave the default cylinder setting
in the preferences empty.
This commit also fixes the incorrect s->value call (should be
s->setValue). I wonder what this did to the default filename before...
