ff9506b21b Import: don't add to new trip while downloading
Since process_imported_dives() can add dives to a newly generated
trip, this need not be done in the downloading code. This makes
data flow distinctly simpler, as no trip table and no add-new-trip
flag has to be passed down to the libdivecomputer glue code.

Moreover, since now the trip creation is done at the import step
rather than the download step, the latest status of the "add to
new trip" checkbox will be considered.

1cd0863cca Import: add add_to_new_trip flag to process_imported_dives()
If this flag is set, dives that are not assigned to a trip will
be assigned to a new trip. This flag is set if the user checked
"add to new trip" in the download dialog of the desktop version.

Currently this is a no-op as the dives will already have been
added to a new trip by the downloading code. This will be removed
in a subsequent commit.

31eb86c733 Dive import: fix logic of process_imported_dives()
The logic in process_imported_dives() was faulty: Dives are merged
trip-wise in a loop. But if only autogenerated trips were supposed
to be merged, the trip would not be added.

Change the logic to always add the trip if it is not merged. To make
the loop easier to read, factor out the merge-trip-into-existing-trips
logic into a separate function.

0249e12589 Import: split process_imported_dives() function
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.

fd196f143a Core: don't copy dive-id on merge dive
The installment of the divelist-undo system has made it unnecessary
to adopt the uniq-id of the merged-into dive. On the contrary, we
want to avoid two dives with the same dive-id in the divelist at
all costs, since get_divenr() still uses the id and thus may fetch
the wrong dive.

Therefore, don't copy the dive-id on merge.

0dfc59f38c Import: add merge_all_trips parameter to process_imported_dives()
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.

1593f2ebad Import: merge dives trip-wise
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.

f8327ed51b Core: move autogroup() into divelist.c
After loading or importing, the caller usually called autogroup()
to autogroup dives if so wished by the user. This has already led
to bugs, when autogroup() was forgotten.

Instead, call autogroup() directly in the process_loaded_dives()
and process_imported_dives() functions. Not only does this prevent
forgetting the call - it also means that autogrouping can be

bfe69239df Import: unglobalize downloadTable
To make data flow more clear, unglobalize the downloadTable object.
Make it a subobject of DownloadThread. The difficult part was making
this compatible with QML, because somehow the pointer to the
download-table has to be passed to the DiveImportedModel. Desktop would
simply pass it to the constructor. But with objects generated in QML
this is not possible. Instead, pass the table in the repopulate()
function. This seems to make sense, but for this to work, we have to
declare pointer-to-dive-table as a Q_METATYPE. And this only works
if we use a typedef, because MOC removes the "struct" from "struct
dive_table". This leads to compilation errors, because dive_table is
the symbol-name of the global dive table! Sigh.

c64c9c923b Cleanup: detangle unregister_dive() and delete_single_dive()
These two functions were called in different contexts:
- unregister_dive(): from the undo-commands to remove the dive
  from the global dive table, but not delete it. The dive was
  already removed from its trip.
- delete_single_dive(): from non-undo code. Most of it not in
  use and removed in a sibling-commit. Here, the dive is supposed
  to be removed from its trip and a new selection is calculated.

delete_single_dive() calls unregister_dive(), which removes the
dive from its trip. Move remove_dive_from_trip() from the former
to the latter and make both functions independent. Instead
of deleting the dive explicitly in delete_single_dive(), call
the delete_dive_from_table() function.

dfd7f98129 Core: don't remove dive from trip in add_dive_to_trip()
All callers of add_dive_to_trip() work on freshly generated dives,
with one exception, that was redundant anyway. Therefore it is not
necessary to remove the dive from a potential previous trip. Move the
responsibility of removing the dive from a trip to the caller,
respectively remove the redundant call. Add a warning message in the
case that trip is set.

Background: On import (either download or file-import) we might not
want to add trips to the global trip-list. For example to enable undo
of import but more generally to detangle that data flow. Thus,
add_dive_to_trip() should not mingle with the global trip-list,
which it has to do if a trip is deleted because the old dive was
removed.

Analysis of the add_dive_to_trip() callers:

1) core/dive.c

pick_trip():
    called on freshly generated merged dive.

finish_split():
    called on two freshly generated split dives.

2) core/divelist.c

create_and_hookup_trip_from_dive():
    called on freshly downloaded dive in dive_cb().
    called on freshly downloaded dive in record_uemis_dive().

autogroup_dives():
    called on dive from get_dives_to_autogroup(), which only
    finds dives that are outside of trips.

combine_trips():
    unused - removed in sibling commit.

try_to_merge_into():
    this call was actually erroneous - dive was already added
    to trip in try_to_merge(). Remove call.

3) core/libdivecomputer.c

dive_cb():
    called on freshly downloaded dive.

4) core/uemis_downloader.c

record_uemis_dive():
    called on freshly downloaded dive.

5) core/load_git.c

create_new_dive():
    called on freshly allocated dive.

6) core/parse.c

dive_end():
    called on freshly parsed dive.

7) desktop-widgets/command_divelist.cpp

DiveListBase::addDive():
    called on dive which is newly added to core.

moveDiveToTrip():
    called on dive that was removed from trip a few lines above.

8) mobile-widgets/qmlmanager.cpp

QMLManager::undoDelete():
    called on dive where divetrip was reset in the previous line.

fba6ec5ad5 Improve OTU calculations
Implement the protocol in Erik Baker's document
"Oxygen Toxicity Calculations". This code uses a
third-order polynomial approximation of Baker's
equation 2. Provision is made for
PSCR and CCR dive logs and dive plans. In the
case of dive logs, the values of o2 sensors are
used if there are data from such sensors. For CCR
only the data from the first O2 sensor is used even if
there are more than one sensor. This is a potential
weakness, but this function is probably NOT the
place to calculate mean o2 values accross all sensors
and to emulate voting logic to reject info from
aberrant sensors.

01d031383c Core: fix crash concerning removal of dives from trips
Commit 6b283e598a replaced the linked
list of dives in a trip by a table. Embarassingly, on dive deletion
the index of the dive in the table was compared for "!= 0" instead
of ">= 0". Thus, the first dive of a trip wouldn't be deleted, which
ultimately led to a crash, as different parts of the code were now
in disagreement over whether the trip is empty or not.

0618aa737f Core: unify insert_trip() and insert_trip_dont_merge()
There were two versions of the insert_trip() function: one
would merge trips if a trip with the same date already existed,
the other wouldn't. The latter was introduced with the dive-list
undo work.

The problem is that the "date" of a trip (i.e. the first dive)
seems ill-defined as this is a volatile value. Moreover in
the context of making dive-import undoable this is a very
dangerous notion, as the caller needs control over when the dives
are added to a trip.

Therefore, unify these two functions and never merge trips.
The decision on merging dives now has to made by the caller.
This will be implemented in a future commit.

1aef22116c More accurate CNS calculations (following comments on github)
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.

2775e7e991 Dive import: remove dive-to-be added from trip before deletion
On dive import, dives to be added may be merged into already
existing dives. In such a case, the dive to be added is deleted.
Before doing so, it must be removed from the trip is belongs to
to avoid corruption of the trip-list.

444354ec9b Cleanup: free all data in clear_table()
Instead of calling free() on all dives, call free_dive() which also
frees additional allocated data, not only the dive struct.

0b57b8d59f Cleanup: move clear_table() to divesite.c
There were two declaration of clear_table(), one in dive.h and one
in parse.h. The definition was in parse.c. Since the parser doesn't
even use the function, move the function and its declaration to
divelist.[ch] and remove the redundant declaration in dive.h.

ac9bab7e2f Autogroup only when selected
Comits f427226b3b and 43c3885249 of the undo series introduced 2 calls
of autogroup_dives() without checking the autogroup global boolean.
This is a bug. An import from DC (for example) then triggers an
autogrouping, the divelist is autogrouped, and the UI button
is off.

This commit solves this. I've chosen for a guard in the autogroup_dives()
that now is a no-op when called when the user did not select autogrouping.
In additon, simplified the other calls to this function, as we do
not need to check before calling any more.

954820aa81 Dive site: explicitly init displayed_dive_site on show widget
The global object "displayed_dive_site" is used to store the
old dive site data for the edit-dive-site widget. The fields
of the widget were initialized from this object in the show
event. Therefore the object was updated in numerous parts of
the code to make sure that it was up-to-date. Instead, move
the initialization of the object to the function that also
initiatlizes the fields. Call this function explicitly before
showing the widget.

This makes the data-fow distinctly easier to understand.

f836b9ae97 Dive list: unify sorting in core and Qt-model

it in the Qt-model code. To this goal, let's start with using
the same sort function.

7067e33596 Undo: select dives after add, remove, merge, split dive commands
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.
