Wrong client_con_st.con member declaration

[Domingo Alvarez Duarte]

Trying to use libdrizzle 2.0 on win32 with sqlite3 I found that the supplied examples doesn't work, the client segfualts because it refer to an unitilized con struct.

Studing the client example I found that the member con of client_con_st structure should be a pointer because on the example there is an attempt to delete it.

typedef struct
{
  drizzle_con_st *con; <<<<< pointer
  drizzle_result_st result;
  drizzle_column_st column;
  client_state state;
  uint64_t row;
} client_con_st;

-------
  for (x= 0; x < client.client_con_count; x++)
  {
    /* This may fail if there is other initialization that fails. See docs. */
    drizzle_con_st *con= drizzle_con_add_tcp(client.drizzle,
                                             host, port, user, password, db,
                                             client.mysql_protocol
                                             ? DRIZZLE_CON_MYSQL
                                             : DRIZZLE_CON_NONE);
    if (con == NULL)
    {
      CLIENT_ERROR("drizzle_con_add_tcp", 0, &client);
    }
    client.client_con_list[x].con = con; <<<<<< assign here as pointer because if not
    drizzle_con_set_context(client.client_con_list[x].con,
                            &(client.client_con_list[x]));

    if (client_process(&client, &(client.client_con_list[x])) == 1) <<<< it will segfault on further calls here
      wait_for_connections++;
  }
---------------

  for (x= 0; x < client.client_con_count; x++)
  {
    drizzle_con_free(&(client.client_con_list[x].con)); <<<<< try to delete
  }

Seems to be this that will work with con as a pointer:

for (x= 0; x < client.client_con_count; x++)
  {
    drizzle_con_free(client.client_con_list[x].con); <<<< pointer that will be deleted
  }
