a96be9af68 qt-models: remove LOG_STP from mobile/desktop
LOG_STP is on longer providing the data needed, since a lot of the startup
is indirectly in QML, furthermore using the xcode project and running profiler

7e12ac262b Dive list: implement DiveTripModelBase::reset()
On desktop, resetting the model is realized by generating a new
model object. This is due to the fact that we have two different
models (tree and list) and for switching between those, we have
to create a new object.

On mobile, currently there are no plans to support the list-mode.
Therefore, there is no reason the recreate the object. Instead,
implement a reset() function that reloads the core data.

358fddd24e Filter: send filterReset via signal
The old code called directly into the DiveListModel. Instead,
send a signal and hook into the signal from the model. This
will allow us to remove the DiveListModel::instance() function.

This, in turn, is a step towards supporting multiple models
at the same time. However, currently the model manually
sets the hidden_by_filter flag in the core and therefore
only one active model is supported at a time.

72c6b83866 Undo: make weight editing undoable
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.

029c9ccf02 Desktop: refactor WSInfoDelegate logic
The WSInfoDelegate (weight-system-info delegate) is used to display
a combo box of known weightsystem-types and auto-fills the weight if
the weightsystem-type is changed.

This would overwrite the weight data of the displayed dive when the
user hovers over the different entries. Moreover, it saves the original
weight in case the user cancels the editing action.

This is not viable when implementing undo of weightsystem changes,
because hovering over entries should not produce individual undo
commands. Instead, implement a special "temporary" row in the
weightsystem model. On canceling of the edit actions, simply reload
the weightsystem from the unmodified dive.

b3253304a5 Desktop: don't connect to remove() slot of model from TableModel
When connecting a model to the TableModel class, it would connect
clicking on an item to the remove() slot of the model.

This breaks the program flow implied by the undo code:
Ui --> Undo-Command --> Model --> UI

Moreover, the naming of the remove() slot is illogical, because
clicks can also have different effects, as for example in the
cylinder-table.

Therefore, move the connect() call from TableModel to the
callers. In the case of TabDiveSite, move the remove() function
from the model to the TabWidget, where it makes more sense.

e46b1e88d9 Selection: move translation of indexes to filter model
The DiveListView caught signals from the DiveTripModel
with the corresponding indexes. However, the DiveListView
is actually connected to the MultiFilterSortModel and
thus has to translate the indexes.

Instead, catch the signals in the MultiFilterSortModel,
transform them and resend. Let the DiveListView get
its signal from the MultiFilterSortModel.

Yes, this makes things less efficient because there is
an extra signal. On the upside, the makes data-flow much

2f77716e8f Dive list: signal correct trip in DiveTripModelTree::topLevelChanged
DiveTripModelTree::topLevelChanged() has pretty complex code, as
it has to handle the fact that when adding/removing a dive from
a trip, the trip can change its position.

The code did not account for the fact that when moving an object
back in the top level list, one has to subtract one from the new
index, because the object was removed somewhere in the front of
the list.

To make matters worse, when an entry stayed where it was, this
was realized by moving the entry right behind itself, which of
course means that it stays where it is. But this meant that in
the by far most common case (no moving) the wrong entry was
updated.

Fix this by subtracting 1 from the new index when moving an
entry to the back.

794066b236 Cylinders: access cylinders with get_cylinder()
Instead of accessing the cylinder table directly, use the get_cylinder()

the function does bound checking. This is crucial for now as the code

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

7c9f46acd2 Core: remove MAX_CYLINDERS restriction
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.

769403a4b2 Planner: copy deco state before passing it to worker thread
The planner has a computeVariations() function that can be run
in a worker thread. The code was not thread safe: a deco_state
object allocated on the stack of the caller was passed down to
the worker thread. It's well possible that the object would go
out of scope before the thread run.

Therefore, when running in the background, copy the object first
and free it in the worker thread.

Side note: Qt makes proper memory management again as difficult
as possible: You can't pass a std::unique_ptr<> to QtConcurrent::run,
because move-only objects are not supported. Not very friendly!

087a80194a Import: keep dive and dive site tables in DiveImportedModel
The DiveImportedModel and DownloadThread used the same table
of dives and dive sites. This made it very hard to keep the
model consistent: Every modification of the download thread
would make the model inconsistent and could lead to memory
corruption owing to dangling pointers.

Therefore, keep a copy in the model. When updating the model,
use move-semantics, i.e. move the data and reset the tables
of the thread to zero elements.

Since the DiveImportedModel and the DownloadThread are very
tightly integrated, remove the accessor-functions of the
dive and dive-site tables. They fulfilled no purpose
whatsoever as they gave the same access-rights as a public
field.

05200f9266 Cleanup: unify idiosyncratic singletons
The way we handle singletons in QML, QML insists on allocating the
objects. This leads to a very idiosyncratic way of handling
singletons: The global instance pointer is set in the constructor.

Unify all these by implementing a "SillySingleton" template. All
of the weird singleton-classes can derive from this template and
don't have to bother with reimplementing the instance() function
with all the safety-checks, etc.

This serves firstly as documentation but also improves debugging
as we will now see wanted and unwanted creation and destruction
of these weird singletons.
