This patch enables vector operation for bdev drivers aio, malloc and
nvme.
The rbd driver still handle only one vector.

These offsets are passed to the bdev I/O functions, which take uint64_t
offsets.

We already require the assert header from the C standard library,
so use that instead of RTE_VERIFY to further isolate DPDK
dependencies.

bdev and copy modules no longer have check_io functions
now - all polling is done via pollers registered when
I/O channels are created.
Other default resources are also removed - for example,
a qpair is no longer allocated and assigned per bdev
exposed by the nvme driver - the qpairs are only allocated
via I/O channels. Similar principle also applies to the
aio driver.
ioat channels are no longer allocated and assigned to
lcores - they are dynamically allocated and assigned
to I/O channels when needed. If no ioat channel is
available for an I/O channel, the copy engine framework
will revert to using memcpy/memset instead.

This matches the general order (LBA start then LBA count) for
the NVMe API.
While here, fix a copy/paste error in a debug message (write
instead of writev).

Our SCSI translation layer only fills 4 version descriptors
meaning the last 30 bytes of the 96 byte standard inquiry
data format are not used. Some compliance tests expect
the full 96 bytes to be returned, even if they are unused.
So zero the remaining bytes (up to 96) if those bytes were
allocated.
This fixes a regression introduced by recent commit d3b58c006.

The translation code currently cheats a bit - it allocates a full 4KB
buffer for any DATA_IN command that is not a READ, and then the
different SCSI commands that fall into this category (INQUIRY,
READ_CAPACITY, MODE_SENSE, etc.) can write as much data as they
want without having to worry about a buffer overrun. Code higher
up the stack makes sure we only send the correct amount of data back
to the iSCSI initiator.
This patch fixes this behavior for standard INQUIRY (EVPD = 0).
Future patches will fix the behavior for other non-READ DATA_IN
commands, at which point we can remove the 4KB allocation and
only allocate the amount of data specified in the CDB.

This will be useful outside of the SCSI code, so put it in the common
string utility file.
Also reorder the parameters so they match the order used in strncpy().

This is the size of a logical block in bytes; 4 GB is more than plenty.
Also allows cleaning up casts to uint32_t in the SCSI translation layer.
