Desktop does not use mark_divelist_changed() anymore - all is done
via the undo machinery. Therefore move this function (and its
counterpart unsaved_changes()) to qmlmanager.cpp.
Ultimately, it probably should be removed from there as well, but

In analogy to the xml-parser add a device-table to git's parser-state.
Currently this is unused. In upcoming commits the git parser will
then be changed to add device nodes in this table instead of the
global device table. The long-term goal being to detach the
parsers from global state and to make dive-import fully undoable.

Add a device_table parameters to Command::importTable() and
add_imported_dives(). The content of this table will be added
to the global device list (respectively removed on undo).
This is currently a no-op, as the parser doesn't yet fill
out the device table, but adds devices directly to the global
device table.

If we want to avoid the parsers to directly modify global data,
we have to provide a device_table to parse into. This adds such
a state and the corresponding function parameters. However,
for now this is unused.
Adding new parameters is very painful and this commit shows that
we urgently need a "struct divelog" collecting all those tables!

We used a typedef "filter_preset_table_t" for the filter preset table,
because it is a "std::vector<filter_preset>". However, that is in
contrast to all the other global tables (dives, trips, sites) that we
have.
Therefore, turn this into a standard struct, which simply inherits
from "std::vector<filter_preset>". Note that while inheriting from
std::vector<> is generally not recommended, it is not a problem
here, because we don't modify it in any shape or form.

This is mostly copy and paste of other git loading code. Sadly,
it adds a lot of state to the parser-state. I wish we could pass
different parser states to the parser_* functions.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
This is a bit painful: since we don't want to modify the filter
presets when the user imports (as opposed to opens) a log,
we have to provide a table where the parser stores the presets.
Calling the parser is getting quite unwieldy, since many tables
are passed. We probably should introduce a structure representing
a full log-book at one point, which collects all the things that
are saved to the log.
Apart from that, this is simply the counterpart to saving to XML.
The interpretation of the string data is performed by core
functions, not the parser itself to avoid code duplication with
the git parser.

Switch the mobile code to use the constraint-based filter. The one
thing that is still commented out is dive-site mode, since mobile

If the dive timestamp changes, the dive could move in the dive list. But the
current dive actually doesn't change (it's still the same dive, right?). Yet
we need to update the dive list as well as the shown dive (especially if this
is after adding a dive, which is first inserted with the current time and then
updated with whatever the user enters).

This allows the mobile UI to reflect the three states that the dive list can be
in:
- changes that haven't been written to local storage
- there potentially are changes in local storage that were not synced with the cloud
- dive list is in sync with cloud storage
The last state could be misleading if the user access the cloud from a
different device and makes changes to the cloud storage from there, but from
the point of view of this device, the states are consistent.

If you pass in the repo name, it isn't treated as cloud storage, but simply as
local git storage and imported (i.e., added) to the current dive list.
This allows the user to work around failed no-cloud->cloud transitions, merge
different accounts, and most importantly deal with situations were conflicts on
the server caused us to move a cache out of the way and potentially make dives
that were on the mobile device inaccessible to the user.
Once a UI is added, this allows the user to recover those dives (realistically
this is not really all that potentially 'dangerous' to do, but it's definitely
something that would best be done after talking to someone who understands the
cloud storage and can guide the user...).

To reset the core data structures, the mobile and desktop UIs
were calling into the dive-list models, which then reset the
core data structures, themselves and the unrelated
locationinformation model. The UI code then reset various other
things, such as the TankInformation model or the map. . This was
unsatisfying from a control-flow perspective, as the models should
display the core data, not act on it. Moreover, this meant lots
of intricate intermodule-dependencies.
Thus, straighten up the control flow: give the C core the
possibility to send a "all data reset" event. And do that
in those functions that reset the core data structures.
Let each module react to this event by itself. This removes
inter-module dependencies. For example, the MainWindow now
doesn't have to reset the TankInfoModel or the MapWidget.
Then, to reset the core data structures, let the UI code
simply directly call the respective core functions.

I'm suspicious that an issue that some people have seen around changes
not being saved is caused by our handling of alreadySaving.
When starting with Subsurface-mobile in no-autosync mode, we were able
to end in a scenario where alreadySaving was true, even though there
were no unsaved changes. And in that case no changes made during such a
session were saved unless the user forced a manual sync with the server.

moves it right next to the actual calls into code that could modify git
storage, and ensures that the flag can never stay set.

When editing a dive on mobile we might have to create a new
dive site. That site is added to the global dive site table
in the undo command. However, the code in QMLManager created
the dive site with create_dive_site*() functions, which already
adds it to the table. The undo command then added the dive
site again leading to a hang of the application.
To solve this problem, create new alloc_dive_site*()
functions that do the same as create_dive_site*()
but do not add it to the table.
