Converts a gdouble to a string, using the '.' as
decimal point.
This function generates enough precision that converting
the string back using funcGLib.ascii_strtod gives the same machine-number
(on machines with IEEE compatible 64bit doubles). It is
guaranteed that the size of the resulting string will never
be larger than glib.types.ASCII_DTOSTR_BUF_SIZE bytes, including the terminating
nul character, which is always added.
