Better support of small files -> they are completely read before sending anything to the bus
Better error support

Two new settings:

- 'small-file-size': size in megabytes under which a file is completely read before
  sending to the bus, ie size under which no on-the-fly emission is done
- 'stream-buffer-size': size in megabytes of the buffer used when sending to the
  bus while reading a remote file. Minimum size is 3.

It implies storing the files in a buffer (possibly on-disk), but it will be a lot more robust.
