0babf8ce81 bdev, copy: move all I/O paths to use I/O channels
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.
