Example spi_write.... spi is not enabled
spi_write_non_blocking..... spi transfer already in progress
usart_setBaudrate(target_baudrate,pourcentageError).... target baud
rate not attainable with specified pourcentage error)
and so on..

I would rather use errno than an new errno_corelib. With RTOS, one has
to save errono for eatch context, thus with errno_corelib, one more
integer(four bytes) on the stack.
