Re: [Libguestfs] [nbdkit PATCH 2/2] ruby: Support zero callback

Add a ruby language binding for the .zero callback, used for
implementing NBD_CMD_WRITE_ZEROES. The caller doesn't have to
return anything, but should use Nbdkit.set_error(errno::EOPNOTSUPP)
to get an automatic fallback to pwrite.
Enhance the example to show the use of the fallback mechanism,
and to serve as a test of Nbdkit.set_error().
Thanks - pushed both.
