In analogy to other tables, this creates a struct that derives
from std::vector<>. This is generally frowned upon, but it works
and is the pragmatic thing for now. If someone wants to "fix" that,
they may just do it.

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.

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.

- show the correct gasmix in the profile;
- make gases available for gas switches in the profile after they have
been added;
- persist gas changes;
- add air as a default gas when adding a dive.
This still has problems when undoing a gas switch - instead of
completely removing the gas switch it is just moved to the next point in the
profile.

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.

When adding a cylinder, it was added at the end of the list.
This would make hidden cylinders visible as the new rule is
to only hide unused cylinders at the end of the list.
Therefore, add the cylinder after the last used cylinder,
i.e. before the first hidden cylinder.
This means that the position where the cylinder is added has
to be hidden in the undo command.

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.

Don't overwrite the full cylinder when editing a single field.

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

This one is a bit more complicated than weight adding, because the

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.
