Small change in stdio :
- add FILE *stderr;
- add STREAM_USB handle and __stream_usb_putchar(FILE * stream, char c) and __stream_usb_getchar(FILE * stream)

A more complicated change in __stream_XXX_putchar (where XXX is usart, mssp, user, usb....) :
- add the stream parameter : example __stream_usart_putchar(FILE * stream, char c)
- change documentation to allow value in the 16 lsb bits of the FILE pointer for the above streams

I use the 16 lsb bits for "pipe" or "channel" identification
