Let's use std::string in the core. Notably, I'd like to make
the numerous main() functions mostly independent of Qt. Some
things will have to remain, such as argument parsing, of course.
This changes the API: instead of returning an error code and
taking a pointer to the actual return-value, return an
std::optional<std::string>> that is set if the function succeeds.
Returning an empty string in the error case might be simpler,
but oh well...

Use the C++-version of membuffer.
This fixes two memory leaks: report_info() on every(!) invocation
and report_error() before the error callback is set.

Had to rewrite the thing, because gcc's warnings don't work
with templatized var-args. Since there is no string-format.cpp
and I didn't want to inline it, moved it to format.cpp.
String formatting is distributed around at least four
headers: membuffer.h, subsurface-string.h, format.h
and format-string.h. This really should be unified!

This may appear a bit ominous, as it doesn't generate a string,
but a vector of strings (one for each line). However, that is
in preparation for the QtQuickification of the profile, where
the text-items take such a list.

We had locale aware formatting functions that generated QStrings.
Create an alternative that creates std::string, since we want that
in the core.
This commit is unfortunate for two reasons:
- The function is called "casprintf()" for analogy with the QString
version. However, the non locale aware function is called
"format_string_std()" for analogy with "format_string()".
Ultimately these names should be unified. Probably, once there
are no membuffer users left.
- This does UTF-16->UTF-8->UTF-16 roundtrips. The core formatting
functions should render UTF-8 and only convert to UTF-16, in
the UI layer.

The combo-boxes (cylinder type, weightsystem, etc.) were controlled
by global models. Keeping these models up-to-date was very combersome
and buggy.
Create a new model everytime a combobox is opened. Ultimately it
might even be better to create a copy of the strings and switch
to simple QStringListModel. Set data in the core directly and
don't do this via the models.
The result is much simpler and easier to handle.

Q_FOREACH and foreach are anachronisms.
Range based for may cause a performance regression: it can
lead to a copy of shared containers (one reason why Qt's
COW containers are broken). However, as long as there is no
user noticeable delay, there is no point in analyzing each case.
And also no point in slapping an 'asConst' on every container
that is looped over.

The memory managements for DeviceDetails was very sketchy.
First of all, sharing a pointer to a structure between threads
seems like a recipe for disaster. Secondly, the structure was
a QObject and when first generated included in the (silly)
Qt object tree, but when generated in the threads it was not.
Clearly, this leaks.
Instead, use value semantics and use local copies of the
structure. I didn't go full length and use std::move to
move the data, because this doesn't work through signals
(which are the wrong abstraction here, but OK) and secondly
I didn't have time to analyze whether the caller still
needs the data after passing it down to the worker thread.
To be able to pass an object through signals, the class
has to be registered in the Qt MetaType system. Super
ugly, but fine for now. Ultimately, this whole thing should
probably be replaced by futures, co-routines, or whatever.
Moreover, this removes the prefix from number of "m_*"
function parameters. By convention, "m_" marks member
variables, which function parameters are not.

printf() is a horrible interface as it does no type checking.
Let's at least use the compiler to check format strings and

There was a pattern of code like
match_action(line, state, dive_action, ARRAY_SIZE(dive_action));

The converted strings were stored in a membuffer and later
converted to std::strings. Generate an std::string directly
to avoid unnecessary copying.
Ultimately, when the core structures are converted to
std::string, there should be no copying of the string data
at all (unless formatting is applied or small string
optimization kicks in, of course).
