This function allocates and initializes the internal state array with a character array.
The allocated memory should be freed by calling mtgp32_free(). para should be one of the elements in the parameter table (mtgp32-param-ref.c). This is the same algorithm with mtgp32_init_by_array(), but hope to be more useful.

This function initializes the internal state array with a 32-bit integer seed.
The allocated memory should be freed by calling mtgp32_free(). para should be one of the elements in the parameter table (mtgp32-param-ref.c).
This function is call by cuda program, because cuda program uses another structure and another allocation method.
