A pipeline can only be used for reading (IOBUF_INPUT) or for
writing (IOBUF_OUTPUT / IOBUF_TEMP). When reading, data flows from
the last filter towards the first. That is, the user calls
iobuf_read(), the module reads from the first filter, which gets
its input from the second filter, etc. When writing, data flows
from the first filter towards the last. In this case, when the
user calls iobuf_write(), the data is written to the first filter,
which writes the transformed data to the second filter, etc.

An iobuf_t contains some state about the filter. For instance, it
indicates if the filter has already returned EOF (filter_eof) and
