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.
