Subject: add serial interface and a few std library functions
changes in usart:
- new functions to setup the serial comunication settings such as baudrate,
parity and stop bits
- init function with most common values
- transmit and receive functions each with a wrapper to send data blocks
changes in libc:
- new file stdio.c with basic implementation of putch, printf still a prototype
- new file string.c with memcpy() function
