a17ad921e2 Replace RTE_VERIFY with assert
We already require the assert header from the C standard library,
so use that instead of RTE_VERIFY to further isolate DPDK
dependencies.

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.

fa29c70938 test/bdevio: detach from build
With the I/O channel changes, this test needs to be rewritten
to be event-based.  bdevio uses the spdk_bdev_do_work() function
to poll for completions, which is built on the check_io functions
that are going away when we move to using I/O channels.

Do not delete the code from the tree - just detach it from the
build and the test scripts for now.

f93bb8a32d Switch spdk_bdev_read/write arg order for length and offset.
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).

Switch from the non-portable <sys/endian.h> functions (htobeXX/beXXtoh)
to the SPDK endian conversion functions.

5a9fa1d146 test/bdev: move large I/O bdevperf test to nightly
We are already testing bdevperf in the previous 'verify' test, and the
I/O splitting is handled by the NVMe-specific tests, so shorten the bdev
tests somewhat by only doing the large I/O bdevperf test in the nightly
test run.
