iobuf: add zerocopy optimization for iobuf_write
* common/iobuf.c (filter_flush): Use 'iobuf->e_d' if configured.
(iobuf_write): Configure 'iobuf->e_d' for 'filter_flush' if
'iobuf->d.buf' is empty and external buffer is larger than threshold.
--
Zero-copy operation in iobuf_write() and filter_flush() allow bypassing
'iobuf->d.buf' for greater performance. This mainly helps OCB
performance where additional memory copies through iobuf stack
can take significant portion of program time.
