Initialization of AES pseudorandom number generator and production of entropy

//Function: Initialization of AES pseudorandom number generator and production of entropy
//Syntax: int initRandAES_1(STATEAES* rstate, char* UsrStr, int LenUsrStr, int LenUsrStr, int AddEntropy, int update)
//Input:
//rstate(pointer to state memory)
//UsrStr (Pointer to User Character String)
//LenUsrStr(length of User String)
//AddEntropy(number of additional requested entropy bytes)
//update(frequency of AES Key Update
//OUTPUT:
//rstate(pointer to initialized state memory)
//RETURN
//n > 0:number of requested but not genrated entropy bytes)
