In a number of places the global 'tank_info' array
is being iterated based on a 'tank_info[idx].name != NULL'
condition.
This is dangerous because if the user has added a lot of tanks,
such loops can reach 'tank_info[MAX_TANK_INFO]'. This is an
out of bounds read and if the 'name' pointer there happens to be
non-NULL, passing that address to a peace of code that tries
to read it (like strlen()) would either SIGSEGV or have undefined
behavior.
Clamp all loops that iterate 'tank_info' to MAX_TANK_INFO.

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.

When generating fake profiles for manually entered dives, fake_dc() and
plan() used different final ascent rates of 5 m/min and 4.5 m/min,

This patch allows the planner to save the last manually-entered
dive planner point of a dive plan. When the plan has been saved
and re-opened for edit, the time of the last-entered dive planner
point is used to ensure that dive planning continues from the same
point in the profile as was when the original dive plan was saved.
Mechanism:
1) In dive.h, create a new dc attribute dc->last_manual_time
with data type of duration_t.
2) In diveplanner.c, ensure that the last manually-entered
dive planner point is saved in dc->last_manual_time.
3) In save-xml.c, create a new XML attribute for the <divecomputer>
element, named last-manual-time. For dive plans, the element would
now look like:
<divecomputer model='planned dive' last-manual-time='31:17 min'>
4) In parse-xml.c, insert code that recognises the last-manual-time
XML attribute, reads the time value and assigns this time to
dc->last_manual_time.
5) In diveplannermodel.cpp, method DiveplannerPointModel::loadfromdive,
insert code that sets the appropriate boolean value to dp->entered
by comparing newtime (i.e. time of dp) with dc->last_manual_time.
6) Diveplannermodel.cpp also accepts profile data from normal dives in
the dive log, whether hand-entered or loaded from dive computer. It
looks like the reduction of dive points for dives with >100 points
continues to work ok.
The result is that when a dive plan is saved with manually entered
points up to e.g. 10 minutes into the dive, it can be re-opened for edit
in the dive planner and the planner re-creates the plan with manually
entered points up to 10 minutes. The rest of the points are "soft"
points, shaped by the deco calculations of the planner.

Internal floating point (FP) calculations should be performed using double
unless there is a very good reason. This avoids headaches with conversions.
Indeed, the vast majority of FP calculations were already done using double.
This patch adapts most remaining calculations. Not converted where things
that were based on binary representations and variables which weren't used
anyway.
An analysis of all instances follows:
core/plannernotes.c, l.404:
This was a comparison between two floats. On the left side, first an integer
was cast to float then multiplied with and integer and divided by a constant
double. The right hand side was an integer cast to a float. Simply divide by
1000.0 first to convert to double and continue with calculations. On the right
hand side, remove the cast, because the integer will be implicitely cast to
double for comparison. This conversion actually emits less instructions,
because no conversion to double and back is performed.
core/planner.c, l.613:
Same analysis as previous case.
subsurface-desktop-main.cpp, l.155:
A local variable representing the version OpenGL version. Turn this into
integer logic. Not only does this avoid dreaded FP rounding issues, it also
works correctly for minor version > 10 (not that such a thing is to be
expected anytime soon).
abstractpreferenceswidget.[h/cpp]:
A widget where the position is described as a float. Turn into double.
desktop-widgets/divelogexportdialog.cpp, l.313:
total_weight is described as float. Use double arithmetics instead. This
instance fixes a truncation warning emitted by gcc.
This reenables the computation of plan variations but now in a separate
thread. Once finieshed, a signal is sent to update the notes.

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.

We currently carry two pressures around for all the samples and plot

cylinder pressure.
That's kind of annoying when we *could* use it for regular sidemount
dives as the secondary pressure.
So start prepping for that instead: don't make it "pressure" and
"o2pressure", make it just be an array of two pressure values.
NOTE! This is purely mindless prepwork. It literally just does a
search-and-replace, keeping the exact same semantics, so "pressure[1]"
is still just O2 pressure.
But at some future date, we can now start using it for a second sensor

This is another attept at the problem if identifying a potentially

It gets rid of the user visable position markers (*!* and ***) and
cirumvents problems with mark-up by first converting the old notes
to plan text (assuming that user only enters plain text in the notes
field as we do in other places as well). Then the automatically added
part is identified by locating the disclaimer in the text (if the user
edited/delted the disclaimer or changed langue in between it is her
problem to manually delete the old plan).
Everything from the disclaimer on is deleted and replaced by the new plan.
If the disclaimer is not found, the new plan is appended to the old notes.

In commit df4e26c875 ("Start sanitizing gaschange event information")
back about a year and a half ago, I started sanitizing the gas switch
event data, allowing gas switches to be associated with a particular
cylinder index rather than just the gas mix that is switched to.
But that initial step only _allowed_ a gas switch event to be associated
with a particular cylinder, the primary model was still to just specify
the mix.
This finally takes the next step, and *always* associates a gas switch
event with a particular cylinder. Instead of then looking up the
cylinder by trying to match gas mixes at runtime, subsurface now looks
it up when loading the dive initially as part of the dive fixup code.
The switch event still has an a separate gas mix associated with it, but
this patch also starts preparing for entirely relying on the gas mix in
the cylinder itself, by starting to pass in not just the event but also
the dive pointer to the routines that look up gas mix details.
