Similar to the standard C vsprintf() function but safer, since it
calculates the maximum space required and allocates memory to hold
the result. The returned string should be freed with g_free() when
no longer needed.
The returned string is guaranteed to be non-NULL, unless format
contains `lc` or `ls` conversions, which can fail if no multibyte
representation is available for the given character.
See also g_vasprintf(), which offers the same functionality, but
additionally returns the length of the allocated string.
