Instead of accessing the cylinder table directly, use the get_cylinder()
function. This gives less unwieldy expressions. But more importantly,
the function does bound checking. This is crucial for now as the code
hasn't be properly audited since the change to arbitrarily sized
cylinder tables. Accesses of invalid cylinder indexes may lead to
silent data-corruption that is sometimes not even noticed by
valgrind. Returning NULL instead of an invalid pointer will make

Instead of using fixed size arrays, use a new cylinder_table structure.
The code copies the weightsystem code, but is significantly more complex
because cylinders are such an integral part of the core.
Two functions to access the cylinders were added:
get_cylinder() and get_or_create_cylinder()
The former does a simple array access and supposes that the cylinder
exists. The latter is used by the parser(s) and if a cylinder with
the given id does not exist, cylinders up to that id are generated.
One point will make C programmers cringe: the cylinder structure is
passed by value. This is due to the way the table-macros work. A
refactoring of the table macros is planned. It has to be noted that
the size of a cylinder_t is 64 bytes, i.e. 8 long words on a 64-bit
architecture, so passing on the stack is probably not even significantly
slower than passing as reference.

We used a table lookup for CNS equivalent times. Turns
out the log of this table falls pretty much on a straight
line for po2 <= 1.5bar. We now fit this tabel two two
lines, one for <= 1.5 bar and one above. This four
parameter fit has half the sum of errors squared
than the five parameter fit using a fourth order
polynomial.
Fitting the log has the advantage that this never
crosses 0, which would have the bad effect of
resulting in negative CNS values as we divide
by the table value.
We don't adopt a maximum pO2 cut-off for the CNS calculation
but rather live with the large values that the interpolation
formula produces when extrapolating.

2) add_imported_dives() calls process_imported_dives() and

dive twice, as this would lead to a double-free() bug.

There were two versions of the insert_trip() function: one

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.

The DiveTripModel places dives after trips in chronologically
ascending mode if the dive and the trip start at the same instant.
But in the core the sort order was undefined. This could lead
to a discrepancy. Therefore, implement the same sort-criterion
in the core code.

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.

With the fixed sematics of get_gasmix to return the new gasmix for
the time of a gas switch (added comments to make this clear), in the
OTU calculation we need the previous gasmix for the interval up to the
current time.

We assume that any dive that gets added to a trip initially gets shown. The
filter logic then needs to make sure it adjusts this number (which then makes
it easy to tell the user how many dives of that trip are visible with the
current filter).

This is consistent with most other free_*() functions in the core
code and will make cleanup of parser state less verbose.

In select_dive(), the selected dive would only be made the
current dive, if it wasn't previously selected. If multiple
dives were selected and the user clicked on one of them which
is not the current dive, then the current dive would be
deselected and thus not be the current dive anymore. The
only remaining dive would not be made the current dive,
because it was already selected. End result: null dive shown.
Therefore, always make the selected dive the current dive,
even if it is already selected.

process_imported_dives() might delete the currently selected

reset the currently selected dive to the last dive.

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.

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.

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.

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.
