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

off_t is problematic for use as a file/block offset: it is signed, and
on 32-bit platforms, it can be 32 bits (depending on the settings of
_FILE_OFFSET_BITS and _LARGEFILE_SOURCE).
The blockdev layer already uses uint64_t to represent offsets; replace
the blockdev module uses of off_t in internal functions with uint64_t
to match.

Fix the existing cases (all missing void in parameter lists) and enable
the warning to prevent new ones from being introduced.

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.

The table of bdev function pointers should not need to be modified at
runtime.

This callback was only used for freeing buffers, but the buffers are now
managed by the bdev core, so none of the free_request callbacks actually
do anything.

Bdev modules need a separate interface than public
consumers of the blockdevs.

Some block devices do not support the unmap operation, and we may add
other optional I/O types in the future. Add a method to check which I/O
types a specific block device supports.

Replace other critical rte_zmalloc() sites that actually depend on the
