Dive sites: prepare for dive site ref-counting Add a dive site table to each dive site to keep track of dives that have been added to a dive site. Add two functions to add dives to / remove dives from dive sites. Since dive sites now contain a dive table, the order of includes had to be changed: "divesite.h" now includes "dive.h" and not vice-versa. This caused some include churn.

Localize global planner state 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).

Core: split process_dives() in post-import and post-load versions 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.

Undo: make undo-system dive site-aware As opposed to dive trips, dive sites were always directly added to the global table, even on import. Instead, parse the divesites into a distinct table and merge them on import. Currently, this does not do any merging of dive sites, i.e. dive sites are considered as either equal or different.

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.

Split out the funtionality to add a dive to an arbitrary dive in the add_dive_to_table_function().

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.

Dive information: fix surface interval calculation 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().

Import: pass a dive table to process_imported_dives() 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. Signed-off-by: Berthold Stoeger <bstoeger@mail.tuwien.ac.at>

Add helper to find the dive closest to a given time 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.

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.

Separate Gtk related code from core logic: divelist This is simplistic & brute force: any function that touches Gtk related data structures is moved to divelist-gtk.c, everything else stays in divelist.c. Header files have been adjusted so that this still compiles and appears to work. More thought is needed to truly abstract this out, but this seems to be a good point to commit this change.
