int firestring_estr_tolower(struct firestring_estr_t
*dest, struct firestring_estr_t *source, const
long start)
firestring_estr_tolower() copies the data in source starting at position
start to dest, replacing any uppercase characters with lowercase
ones by using tolower(3). source and dest can be the same
string.
0 if the string was copied successfully; 1 if there was insufficient space in
destination for the copy to occur.
