Recently (d16a9f118a) the tankinfo table was made dynamic, which
means that the default tankinfos are added programatically.
Thereby, the wrong function was used for AL* type of cylinders:
metric instead of imperial. Fix those.

A user complained about the default cylinders list. Provide
a preferences option to turn this off.
When changing the preferences, the tank-info model will be
completely rebuilt. Currently, this is a bit crude as this
will be done for any preferences change.

There was a tank info with an empty name. According to a comment,
this is needed for the "no cylinder" case. However, we now support
empty cylinder tables, so this is not needed anymore. Therefore,
remove it.
Make sure that the user can still enter the empty name, just in
case. But don't save the size and pressure in that case.

This is obviously a pure code-hygiene thing. But with the new
dynamic tank info table, this becomes trivial, so let's do it.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
The list of known tank types were kept in a fixed size table.
Instead, use a dynamic table with our horrendous table macros.
This is more flexible and sensible.
While doing this, clean up the TankInfoModel, which was leaking
memory.

In a previous commit, auto-filling of weight based on type was
changed to be only performed if the user hadn't already set a
weight, by testing for weight=0.
However, when the user edited the type and tabbed back and forth,
that counted as an edit and therefore the weight would not
change anymore.
To refine this, introduce an "auto_filled" flag to the weightsystem,
which is set if the weight is automatically filled and cleared if
the weight is edited. Update the weight if it was zero *or* auto-filled.
The flag is not saved to disk, but that should be acceptable. If the
user saves and reloads, we can assume that they meant the weight
to be set to the default value.

For consistency with equipment, use our table macros for pictures.
Generally tables (arrays) are preferred over linked lists, because
they allow random access.
This is mostly copy & paste of the equipment code.
Sadly, our table macros are quite messy and need some revamping.
Therefore, the resulting code is likewise somewhat messy.

When we had fixed-sized cylinder arrays, the planner used the last
empty cylinder for "surface air". This was not recognized by the UI
as a separate cylinder, because "empty cylinder" was the sentinel for
the end of the table. The conversion to dynamically sized cylinder
tables broke this code: everytime the surface segment is changed,
a new dummy cylinder is added, which is visible in the UI.
As a very temporary stop-gap fix, emulate the old code by creating
a cylinder and then setting the end-of-table to before that cylinder.
This means that we have to loosen the out-of-bound checks.
That's all very scary and should be removed as soon as possible.

This will be temporarilly used by the planner to mark consumption of
air at the surface. Do this by creating a new function add_cylinder,
which replaces add_to_cylinder_table() and takes care of always adding
a dummy cylinder at the end of the table. Make the original
add_to_cylinder_table() local, so that it cannot be accessed anymore.

Don't overwrite the full cylinder when editing a single field.
Implement three "modes": editing of type, pressure and gasmix.
Don't consider individual fields, because some of them are
related. E.g. you can change the gasmix by setting the MOD.

Use the user-editable MOD-pO2 preferences value when creating

Currently, the caller is responsible for not reusing a freed
weightsystem / cylinder or resetting the description field to
null. This is very unfriendly. Set the description field to null,
because that allows us to call free_* repeatedly on the same
object. Use the new behavior to make the weightsystem model code
a bit cleaner.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
Implement the EditWeight undo command. Since there is common code
(storage of the old weight), this creates a common base class for
RemoveWeight and EditWeight. The model calls directly into the undo
command, which is somewhat unfortunate as it feels like a layering
violation. It's the easy thing to do for now.

Instead of freeing internal data of the weightsystem structure,
call the free_weightsystem function (which has to be made extern
at first). This makes things more future-proof, should the
weightsystem struct ever be extended.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
This one is a bit more complicated than weight adding, because the
multiple-dive case is not well defined. If multiple dives are selected,
this implementation will search for weights that are identical to the
weight deleted in the currently shown dive. The position of the weight
in the list is ignored.

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
debugging much easier.

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.

Replace the fixed-size weightsystem table by a dynamically
relocated table. Reuse the table-macros used in other parts
of the code.
The table stores weightsystem entries, not pointers to
weightsystems. Thus, ownership of the description string is
taken when adding a weightsystem. An extra function adds
a cloned weightsystem at the end of the table.

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]).
