In 35a331a9 we added a new API that enables peer-2-peer (P2P) copies
between NVMe SSDs using Controller Memory Buffers (CMBs) that support
DMA operations. Add documentation for the API, the example application
(cmb_copy) and for P2P setup and operation.
Note that this new API is currently marked experimental.

Briefly tested with SPDK target via bdevio
through both vhost-user and QEMU's virtio-pci.
vhost-blk driver is not mentioned in any doc yet.
A virtio-blk bdev can be created as following:
`construct_virtio_user_blk_bdev /tmp/virtio.0 MyVirtioBlk0 --vq-count 16`
`construct_virtio_pci_blk_bdev 0000:01:00.0 MyVirtioBlk1`
or
```
[VirtioUser0]
Path /tmp/vhost.0
Type Blk
Queues 16
[VirtioPci]
Enable Yes
```
If `Type` field is not present, the VirtioUser
section will be parsed as a SCSI one, preserving
backward compatibility.
