Harald Welte 92c44c572e firmware/sniffer: Add + use 16bit ringbuffer ...

So far, we use a uint8_t ring buffer as "FIFO" between USART Rx
interrupt and main context.  That's fine for expressing the bytes we
receive.  However, if we also want to report USART errors synchronously
in that stream, we actually need more bits to express those.

Reporting USART errors via the ring buffer is the only way how the
sniffer code can know in which TPDU the error occurred.  Reporting them
any other way (global variable, ...) would loose the timing relationship
where in the received stream the error occurred.

This change just changes the ringbuffer from 1024-entry 8bit to
512-entry 16bit and doesn't add any error reporting.
