Yes, these functions are dodgy, let's say, by design.
It is not really possible to make such interface consistent
and make one function working with both kinds of strings,
std::string and C-string.
The assumption is that user of gstrdup will learn
its implementation to understand how to use it.
Meaning, to keep value of size consistent with number of non-null
