db516b6d4e Profile: Fix the Initial Gasmix.
Fix the initial gasmix that is shown in the tank bar of the profile.

Also add a meaningful gas name for gases with negative values for
percentages.

@bstoeger: This is a side effect of the `event_loop` functionality
introduced as part of #4198. In the case of an `event_loop("gasmix")`
this does not take into account the edge case where there is no
gaschange event at the very beginning of the dive, and the first gasmix
is implicitly used as the starting gasmix. This happens for planned and
manually added dives, but also for some dive computers.
We are using the
same kind of loop in a number of other places in `core/profile.cpp`,
`core/dive.cpp`, `core/gaspressures.cpp`, and `profile-widget/tankitem.cpp`,
and I am wondering if we should be converting these to use
`gasmix_loop` instead to avoid being bit by this special case?

Also, turn it to use std::string instead of writing into a
global(!) buffer. This was not reentrant.

9c726d8d6f core: move gas_volume() to cylinder_t
Feels natural in a C++ code base.

The commit is somewhat complex, because it also changes the
return type to volume_t. The units system really needs some
work. :(

b34116e2e2 core: make calculate_cns() member of dive_table
This function implicitely accessed the global divelog. To make
that explicit make it a member of dive_table, such that the

284582d2e8 core: turn divecomputer list into std::vector<>
Since struct divecomputer is now fully C++ (i.e. cleans up
after itself), we can simply turn the list of divecomputers
into an std::vector<>. This makes the code quite a bit simpler,
because the first divecomputer was actually a subobject.

Yes, this makes the common case of a single divecomputer a
little bit less efficient, but it really shouldn't matter.
If it does, we can still write a special std::vector<>-
like container that keeps the first element inline.

This change makes pointers-to-divecomputers not stable.
So always access the divecomputer via its index. As
far as I can tell, most of the code already does this.

27dbdd35c6 core: turn event-list of divecomputer into std::vector<>
This is a rather long commit, because it refactors lots of the event
code from pointer to value semantics: pointers to entries in an
std::vector<> are not stable, so better use indexes.

To step through the event-list at diven time stamps, add *_loop classes,
which encapsulate state that had to be manually handled before by
the caller. I'm not happy about the interface, but it tries to
mirror the one we had before.

f120fecccb core: use std::vector<> to store divecomputer samples
This is a hairy one, because the sample code is rather tricky.

There was a pattern of looping through pairs of adjacent samples,
for interpolation purposes. Add an range adapter to generalize
such loops.

Removes the finish_sample() function: The code would call
prepare_sample() to start parsing of samples and then
finish_sample() to actuall add it. I.e. a kind of commit().

Since, with one exception, all users of prepare_sample()
called finish_sample() in all code paths, we might just add
the sample in the first place. The exception was sample_end()
in parse.cpp. This brings a small change: samples are now
added, even if they could only be parsed partially. I doubt
that this makes any difference, since it will only happen
for broken divelogs anyway.

48f7828d10 profile: C++-ify plot_info
Use more C++ style memory management for plot_info: Use std::vector
for array data. Return the plot_info instead of filling an output
parameter. Add a constructor/destructor pair so that the caller
isn't bothered with memory management.

The bulk of the commit is replacement of pointers with references,
which is kind of gratuitous. But I started and then went on...

Default initializiation of gas_pressures made it necessary to convert
gas.c to c++, though with minimal changes to the code.

32a08735c3 profile: fix string formating in profile.cpp
ae299d5e66 introduced a format-
string bug by splitting a format-string in two and splitting
the arguments at the wrong place.

The compiler doesn't warn in this case, because the format-
string is passed through translate(...).

This should have crashed, but for some reason didn't, at least
on Linux.

Fix the arguments.

ae299d5e66 profile: use C++ string functions to format plot data

in preparation for the QtQuickification of the profile, where
the text-items take such a list.
