afe363fa85 Optional anonymization upon export
Add a checkbox that triggers replacement of all English characters by
x's in notes, buddy, dive guide and (while we are at it) suit.

This is ment for people sharing logs for debugging that are concious
about privacy issues. It leaves the lenth of strings in tact as well
as special charcters as those might be needed to track down a particular
parsing problem.

6e4a253896 Profile: fix SAC calculation for air dives
Commit f5b11daffd changed gasmix
arguments and return values to be passed by value instead of
using pointers.

Notably, get_gasmix() is fed a default-value and returns a
new value. In the old code, NULL was passed in in a first
loop iteration and non-NULL was always returned in the first
iteration. Thus, an equality comparison of passed-in an
returned gasmix would always fail in the first loop iteration.

The new code passed in air as default. Now if air was also
returned, then the matching gases were not calculated in
calculate_sac(). To revert to the old behavior, pass in
an invalid gasmix.

Moreover, give names to the invalid and air gasmixes.

2bd0c2143e Cleanup: constify get_units()
get_units() returns a pointer to the units struct in the preferences.
Callers should not modify the preferences via this struct, therefore
make the return value point to const.

This is a small step in constifying the global preferences structure.

605e1e19ed Cleanup: const-ify functions taking pointers to events
This is another entry in the series to make more things
"const-clean" with the ultimate goal of merge_dive() take
const pointers.

This concerns functions taking pointers to events and
the fallout from making these const.

The somewhat debatable part of this commit might be
that get_next_event() is split in a two distinct
(const and non-const) versions with different names,
since C doesn't allow overloading. The linker should
recognize that these functions are identical and remove
one of them.

360f07e453 Cleanup: pass gasmix by value
In a previous commit, the get_gasmix_* functions were changed to
return by value. For consistency, also pass gasmix by value.

Note that on common 64-bit platforms struct gasmix is the size
of a pointer [2 * 32 bit vs. 64 bit] and therefore uses the
same space on the stack. On 32-bit platforms, the stack use
is probably doubled, but in return a dereference is avoided.

Supporting arbitrary gas-mixes (H2, Ar, ...) will be such an
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]).

5c4569247a Cleanup: unify get_gas_at_time() and get_gasmix()
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.

f5b11daffd Cleanup: return gasmix by value
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.

325b8bba35 Undo: remember deleted trip in UndoRemoveDivesFromTrip::undo()
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.

2c6b1a99af Cleanup: simplify dive_getUniqID()
dive_getUniqID() is used to create unique dive ids, which are
stable during application lifetime. It was passed a dive, checked
that the id was not set (if it was that it is know to the application)
and set a new id (in contradiction to its name!) if it hadn't any.

There were three callers:

alloc_dive(): called the function on a zeroed dive struct.
fixup_dive(): called the function only if the dive had a 0 id.
MainWindow::setupForAddAndPlan(): called the function on a zeroed dive
struct.

Thus, in all three callers the id is guaranteed to be zero and
the whole keeping-track-of-ids logic is moot. Remove the logic,
don't pass a dive struct to dive_getUniqID() and move the function
to the C-backend.

b9174332d5 Read and write divemode changes (xml and git)
This provides for reading of divemode change events from dive logs
and for writing them to dive logs. This applies to xml and git
divelogs. Divemode change events have the following structure:
event->name = "modechange"
event->value = integer corresponding to enum dive_comp_type (dive.c),
reflecting the type of divemode change (OC, CCR, PSCR, etc).

In the dive log file, the event value is written as a string that
corresponds to each of the enum values, e.g.
<event name='modechange' divemode='OC' />
This xml is also read from the dive log file and translated to an
appropriate value of event->value.

The file diveeventitem.cpp was udated to reflect this new way of
dealing with divemode change events.

27a0542220 Implement bailout outside of the dive planner
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.

cf377beb2e Incorporate bailout events in CCR & PSCR gas calculations.
This is a first step to interpret bailout events.
1) The event structures have a new attribute: divemode.
   Currently interpreted dive modes are OC, CCR, PSCR.
2) When doing fill_pressures(), the calculation is aware
   of divemode. When divemode is OC (==bailout), then
   the appropriate calculations of gas pressures are done.
3) Two new functions get_next_divemodechange() and
   get_divemode_at_time() are created to find divemode
   changes in the events linked list and to determine
   the dive mode at any point during the dive.
4) fill_pressures gets a small amendment to facilitate
   the correct calculations, depending on divemode.
The cases where fill_pressures() is used *outside the planner*
are changed. The result is that, for dives with bailout, the
correct gas pressures are shown on the dive profile. The
deco for bailout dives is not yet correct. This is the
next step.

920ff15f71 Planner: don't return static data in fake_dc()
fake_dc() used to return a statically allocated dc with statically
allocated samples. This is of course a questionable practice in
the light of multi-threading / resource ownership. Once these
problems were recognized, the parameter "alloc" was added. If set
to true, the function would still return a statically allocated
dc, but heap-allocated samples, which could then be copied in
a different dc.

All in all an ownership nightmare and a recipie for disaster.
The returned static dc was only used as a pointer to the samples
anyway. There are four callers of fake_dc() and they all have access
to a dc-structure without samples. Therefore, change the semantics
of fake_dc() to fill out the passed in dc. If the caller does
not care about the samples, it can simply reset the sample number
to zero after work.

9a8bab21c9 Improve profile display in planner
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.

Improvements: Improve code for profile display in dive planner

This responds to #1052.
