Added missing prototype for puts() in stdio.h.
Implemented a basic serial interface using COM0 which can be accessed
with the system call sys_puts as well as the library functions rsputs()
and rsprintf().
Renamed puts() in con.c to con_puts() and made the function static to
avoid interference with the library function puts().
