A new API to deploy zero-copy command submission. The new API takes I/O
vectors list and number of I/O vectors to submit as input parameters
when initiating the command. New API must be used if working with
iSER transport option.

Introducing new transport abstraction, with additional support
in iSER transport layer. Also adding new zero-copy API that is
needed in iSER case.

- Adding iser as an additional block driver
changes from v2:
- Splitting iser support and new API into two patches
- Removing option
iSER is a new transport layer supported in Libiscsi,
iSER provides a zero-copy RDMA capable interface that can
improve performance.
In order to use the new iSER transport one need to have RDMA supported HW
and to choose iser as the protocol name in Libiscsi URI.
For now iSER memory buffers are pr

The hard-coded default alignment is BDRV_SECTOR_SIZE, however this is not

Allow qemu to build on 32-bit hosts without 64-bit atomic ops.
Even if we only allow 32-bit hosts to multi-thread emulate 32-bit

64-bit atomic operation. Do so by dropping back to single-step.

Some virtual devices (e.g. NVDIMM) use the host memory backend to map

the mapping has to be managed out of QEMU. In order to reuse other parts
