1479 o correctly extends the timeout depending on the size of all
1480 queued messages for both transmit and receive
1481 o will not continue with receive if transmit times out
1482 o ensures that the error callback is done for all queued tx

1485 the callback, and does not overwrite an earlier error
1486 o logic in i2c_probe now correct
1487 - add "vprintf()" function so that "panic()" function can be
1489 - many Hymod board changes
