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()

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.

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.

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.

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.

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.

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

Then each dive is inserted in a one-by-one manner to into the global

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

invasive change that going back to pointers is probably the
least of our worries.
This commit is a step in const-ifying input parameters (passing
by value is the ultimate way of signaling that the input parameter
will not be changed [unless there are references to said parameter]).

There were two functions for getting gas-mixes at a certain timestamp:
- get_gasmix() for repeated queries.
- get_gas_at_time() for a single query.
Since the latter is a special case of the former, simply call
the former in the latter. Moreover, rename to get_gasmix_at_time()
for consistency.
Replace on get_gasmix() call, which was outside of a loop by the
corresponding get_gasmix_at_time() call.

Currently, get_gasmix_from_event() and get_gasmix() return pointers
to either static or to (possibly changing) dive data. This seems like
a dangerous practice and the returned data should be used immediately.
Instead, return the gasmix by value. This is in preparation of
const-ifying input parameters of a number of core functions, which
will ultimately let the merge() function take const-arguments in
preparation of undo of dive-merging.
On common 64-bit systems gasmix (two "int"s) is the size of a pointer
and can be returned in a register.
On 32-bit systems a pointer to the struct to be filled out will be
passed.
Since get_gasmix() now returns a value, the first invocation is
tested by a NULL-initialized "struct event *". Document this in
a comment.

If the last dive of a trip is removed, the trip is deleted.
On redo the dive is added to a non existing trip, leading to a
segfault.
Therefore, keep a copy of the trip to reinstate it on redo.
Note: this cannot work for a sequence of multiple commands.
One would have to rewrite the whole undo-history. Nevertheless,
let's do this as a stop-gap measure.

If we breathe from a cylinder with invalid start or
end pressures, we cannot reliably compute the total gas
use and thus the SAC. So we should not pretend to do so.
A better fix would compute the total SAC for only those
segements that have valid start and end pressures.

This is the second step for implementing bailout. The indirect
calls to fill_pressures through add_segment() (in deco.c) are
addressed. Bailout is now fully implemented in the dive log but
not in the dive planner.
1) The parameters to add_segment() are changed to take a
divemode as the second last parameter, and not a *dive.
2) Call to add_segment() in profile.c and in divelist.c are
adapted. In divelist.c some calls to add_segment were left
using dc-> divemode instead of possible bailout. This appears
tp be the most appropriate route.
3) The functions get_divemode_from_time() and get_next_divemodechange()
in dive.c have had some small changes.
4) The calls to get_segment(0 in planner.c were changed to reflect
the new parameter list, but not updated to reflect bailout. This
is the next step.

For UI responsiveness, we need to be able to run the planner in the background. This needs the
planner state to be localized (and we need to pass a pointer around).
In order to not let too many lines overrun (and to save typing in the future)
I have renamed instances of struct deco_state to ds. Yes this should have gone
to a separate commit but I accidentally commit --amend'ed it.
Computing of planner variations is temporarily disabled.

Identify previous dives for CNS calculation in a similar way as it
is done for previous dives for deco calculation.
This is done to identify the previous dives dynamically when moving
around date/time of a dive in the planner.
Signed-off-by: Stefan Fuchs <sfuchs@gmx.de>
When changing the date/time of a dive in the planner the dive may end
up in a totaly new position in respect to date/time of other dives in
dive list table. It can be moved to the past or the future before or after
other existing dives. It also could overlap with an existing dive.
This change enables identification of a new "virtual" dive list position
and based on this starts looking for previous dives.
Then it (as before the change) does init the deco calculation with any
applicable previous dive and surface interval.
If some of these applicable dives overlap it returns a neg. surface time
which is then used in the planner notes to prohibit display of results.

In commit e1b880f4 "Profile support for multiple concurrent pressure
sensors" I had mindlessly hacked away at some of the sensor lookups from
the plot entries to make it all build, and forgotten about my butchery.
Thankfully Jan and Davide noticed in their multi-cylinder deco dives
that the deco calculations were no longer correct.
This uses the newly introduced "get_gasmix()" helper to look up the
currently breathing gasmix, and fixes the deco calculations.

This is a very timid start at making us actually use multiple sensors
without the magical special case for just CCR oxygen tracking.
It mainly does:
- turn the "sample->sensor" index into an array of two indexes, to
match the pressures themselves.
- get rid of dive->{oxygen_cylinder_index,diluent_cylinder_index},
since a CCR dive should now simply set the sample->sensor[] indices
correctly instead.
- in a couple of places, start actually looping over the sensors rather
than special-case the O2 case (although often the small "loops" are
just unrolled, since it's just two cases.
but in many cases we still end up only covering the zero sensor case,
because the CCR O2 sensor code coverage was fairly limited.
It's entirely possible (even likely) that this migth break some existing
case: it tries to be a fairly direct ("stupid") translation of the old
code, but unlike the preparatory patch this does actually does change
some semantics.
For example, right now the git loader code assumes that if the git save
data contains a o2pressure entry, it just hardcodes the O2 sensor index
to 1.
In fact, one issue is going to simply be that our file formats do not
have that multiple sensor format, but instead had very clearly encoded
things as being the CCR O2 pressure sensor.
But this is hopefully close to usable, and I will need feedback (and
maybe test cases) from people who have existing CCR dives with pressure
data.

It turns out that we are starting to have users that have logs that go

NOTE! With us now supporting dates earlier in 1900, this also makes
"utc_mktime()" always add the "1900" to the year field. That way we
avoid ever using the fairly ambiguous two-digit shorthand.
It didn't use to be all that ambiguous when we knew that any two-digit
number less than 70 had to be 2000+. Now that we support going back to
earlier in the last centiry, that certainty is eroding.

If we want to keep the selected dive "close" to where it was before an
operation (whether a delete, or a reload, or something like that), then
the most intuitive thing to do appears to be to select either the same
dive again (if it still exists), or one very close to it in time. This
helper allows us to identify the dive in the current dive list that is
closest to the given time.
We do this in the C code to ensure that we look at all dives in the
dive_table - based on the id that is returned the UI can then figure out
where this dive is currently shown.

Having subsurface-core as a directory name really messes with

And while cleaning up the resulting change in the path name for include

This could have been handled in more commits, but since this requires a
make clean before the build, it seemed more sensible to do it all in one.
