Upon reception of the SR_DF_END packet, communicate this end of the
datafeed event to libsigrokdecode. Which in turn can invoke the
protocol decoders' optional decode_end() method before closing the
output stream.
This allows to flush previously accumulated and not yet committed output
data, emit warnings about unterminated frames/transfers/transactions,
etc. Which minimizes the potential for loss of partial information
about started yet not fully completed conditions in decoded protocols.
