Allocating memory by using built in allocation pool

fcgi Function has built in allocation memory management, it will be auto free for every session request.

Sample:

void getProfile(ffunc_session_t * session) {
        int* newId = (int*)ffunc_alloc(session, sizeof(int));
	flog_info("%s\n", "you reach here with get Request");

	if (session->query_str) {
	    char *userID = (char*) ffunc_get_query_param(session, "userId",  sizeof("userId") - 1);
	    if (userID) {
                *newId = atoi(userID);
		write_out("This user %s has new id= %d\n", userID, *newId); // the param @userId
            }
	}
}
