[Libguestfs] [PATCH v2 nbdkit 0/6] Add truncate filter and other fixes.

[Richard W.M. Jones]

I have dropped the map filter from this series for now while I try to
get it working.

However I think the truncate filter is in a good shape.  This
incorporates all feedback from Eric's review.

Also there are three small fixes to the filter code, all revealed when
I was testing using multiple filters which we'd not done much of
before.
