These were declared in dive.h, which makes no sense.
This should have been chnaged a long time ago.

This is a messy commit, because the "qPref" system relies
heavily on QString, which means lots of conversions between
the two worlds. Ultimately, I plan to base the preferences
system on std::string and only convert to QString when
pushing through Qt's property system or when writing into
Qt's settings.

To my understanding, declaring empty parameter lists using "(void)"
is an artifact from the bad old K&R times, when functions were
declared without(!) parameters. Which in hindsight was an absolute
recipe for disaster. So for backwards compatibility, functions
without parameters had to be declared using "(void)" as "()"
could also mean "any function".
That was 40 years ago. Meanwhile, C++ introduced references,
which made it a necessity to declare the function parameters.
So "(void)" is redundant and inconsistent in C++ code and
just makes no sense.
Remove it.

The memory management and string concatenation was hard to follow.
Since the mobile files ios.cpp and android.cpp were already
converted to C++, let's do the same for Unix, Windows and MacOS.
Simply store the default directory and filename in a function-level
static string. Thus, it will be initialized on first call and
freed on application exit. Since the std::string data is
guaranteed to be contiguous and zero-terminated, it can be used
from C code.
