Split the process_imported_dives() function in two:
1) process_imported_dives() processes the dives and generates
a list of dives and trips to be added and removed.
2) add_imported_dives() calls process_imported_dives() and
does the actual removal / addition of dives and trips.
The goal is to split preparation and actual work, to
make dive import undo-able.
The code adds extra checks to never merge into the same
dive twice, as this would lead to a double-free() bug.
This should in principle never happen, as dives that
compare equal according to is_same_dive() are merged
in the imported-dives list, but perhaps in some pathologival
corner-cases is_same_dive() turns out to be non-transitive.

When importing log-files we generally want to merge trips. But
when downloading and the user chose "generate new trip", that
new trip should not be merged into existing trips.
Therefore, add a "merge_all_trips" parameter to process_imported_dives().
If false only autogenerated trips [via autogroup] will be merged.
In the future we might want to let the user choose if trips
should be merged when importing log-files.
Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>
The old way of merging log-files was not well defined: Trips
were recognized as the same if and only if the first dives
started at the same instant. Later dives did not matter.
Change this to merge dives if they are overlapping.
Moreover, on parsing and download generate trips in a separate
trip-table.
This will be fundamental for undo of dive-import: Firstly, we
don't want to mix trips of imported and not-yet imported dives.
Secondly, by merging trip-wise, we can autogroup the dives
in the import-data to trips and merge these at once. This will
simplify the code to decide to which trip dives should be
autogrouped.

After loading or importing, the caller usually called autogroup()
to autogroup dives if so wished by the user. This has already led

Update table of maximum oxygen exposure durations, used in CNS calulations.
This table shows the official NOAA maximum O2 exposure limits
(in seconds) for different PO2 values. It also gives
slope values for linear interpolation for intermediate PO2 values
between the tabulated PO2 values in the 1st column.
Top & bottom rows are inserted that are not in the NOAA table:
(1) For PO2 > 1.6 the same slope value as between
1.5 & 1.6 is used. This exptrapolation for PO2 > 1.6 likely
gives an underestimate above 1.6 but is better than the
value for PO2=1.6 (45 min). (2) The NOAA table only
tabulates values for PO2 >= 0.6. Since O2-uptake occurs down to
PO2=0.5, the same slope is used as for 0.7 > PO2 > 0.6.
This gives a conservative estimate for 0.6 > PO2 > 0.5. To
preserve the integer structure of the table, all slopes are
given as slope*10: divide by 10 to get the valid slope.
The columns below are:
po2 (mbar), Maximum Single Exposure (seconds), single_slope,
Maximum 24 hour Exposure (seconds), 24h_slope */
Then update Calculations of the CNS for a single dive -
this only takes the first divecomputer into account.
The previous version of the code did a table lookup and
used the max O2 exposure for the next-higher PO2 category.
This gave a shorter max O2 exposure time and a higher CNS
contribution for a specific dive segment, resulting in a
slightly conservative value of CNS, often some 2 - 3 % too high.
This code does an interpolation for PO2 values inbetween
PO2 entries in the lookup table and therefore results in a more
accurate maximum O2 exposure time for that PO2.
The maximum O2 exposure duration for each segment
is also calculated based on the mean depth of the two
samples (start & end) that define each segment. The CNS
contribution of each segment is found by dividing the
time duration of the segment by its maximum exposure duration.
The contributions of all segments of the dive are summed to
get the total CNS% value. This is a partial implementation
of the proposals in Erik Baker's document "Oxygen Toxicity Calculations" */
Overall, this PR does not radically alter the existing CNS calculation,
it only makes it more accurate and more consistent by doing
interpolation and by using mean segment depth to find PO2.

Select the proper dives after the add, remove, split and merge
dives commands on undo *and* redo. Generally, select the added
dives. For undo of add, remember the pre-addition selection.
For redo of remove, select the closest dive to the first removed
dive.
The biggest part of the commit is the signal-interface between
the dive commands and the dive-list model and dive-list view.
This is done in two steps:
1) To the DiveTripModel in batches of trips. The dive trip model
transforms the dives into indices.
2) To the DiveListView. The DiveListView has to translate the
DiveTripModel indexes to actual indexes via its QSortFilterProxy-
model.
For code-reuse, derive all divelist-changing commands from a new base-class,
which has a flag that describes whether the divelist changed. The helper
functions which add and remove dives are made members of the base class and
set the flag is a selected dive is added or removed.
To properly detect when the current dive was deleted it
became necessary to turn the current dive from an index
to a pointer, because indices are not stable.
Unfortunately, in some cases an index was expected and these
places now have to transform the dive into an index. These
should be converted in due course.

large parts the same thing as undo/redo of dive deletion (just the

The original undo-code was fundamentally broken. Not only did it leak
resources (copied trips were never freed), it also kept references
to trips or dives that could be changed by other commands. Thus,
anything more than a single undo could lead to crashes.
Two ways of fixing this were considered
1) Don't store pointers, but unique dive-ids and trip-ids.
Whereas such unique ids exist for dives, they would have to be
implemented for trips.
2) Don't free objects in the backend.
Instead, take ownership of deleted objects in the undo-object.
Thus, all references in previous undo-objects are guaranteed to
still exist (unless the objects are deleted elsewhere).
After some contemplation, the second method was chosen, because
it is significantly less intrusive. While touching the undo-objects,
clearly separate backend from ui-code, such that they can ultimately
be reused for mobile.
Note that if other parts of the code delete dives, crashes can still
be provoked. Notable examples are split/merge dives. These will have
to be fixed later. Nevertheless, the new code is a significant
improvement over the old state.
While touching the code, implement proper translation string based
on Qt's plural-feature (using %n).

Dives were directly imported into the global dive table and then
merged in process_imported_dives(). Make this interface more flexible,
by passing an independent dive table.
The dive table of the to-be-imported dives will be sorted and merged.
Then each dive is inserted in a one-by-one manner to into the global
dive table.
This actually introduces (at least) two functional changes:
1) If a new dive spans two old dives, it will only be merged to the
first dive. But this seems like a pathological case, which is of
dubious value anyway.
2) Dives unrelated to the import will not be merged. The old code
would happily merge dives that were not even close to the
newly imported dives. A surprising behavior.

The old surface interval calculation had fundamental issues:
1) process_all_dives(), which calculates the statistics over *all*
dives was used to get the pointer to the previous dive.
2) If two dives in the table had the same time, one of those would
have been considered the "previous" dive.
3) If the dive, for which the surface interval is calculated is
not yet in the table, no previous dive would be determined.
Fix all this by creating a get_surface_interval() function and
removing the "get previous dive" functionality of process_all_dives().

process_dives() is used to post-process the dive table after loading
or importing. The first parameter states whether this was after
load or import.
Especially in the light of undo, load and import are fundamentally
different things. Notably, that latter should be undo-able, whereas
the former is not. Therefore, as a first step to make import undo-able,
split the function in two versions and remove the first parameter.
It turns out the the load-version is very light. It only sets the
DC nicknames and sorts the dive-table. There seems to be no reason
to merge dives.
