Now that the NVMe and I/OAT libraries depend on the log library, log
needs to be built earlier in the Travis-CI unit test script.

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

it already includes the tested C file directly and doesn't depend on any

devices and transport devices located in different socket, with
this patch, the NVMf target will print a warning message to remind
the user that your configuration is not optimal.

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.

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.

This patch adds a basic framework for creating I/O channels
for I/O devices. An spdk_io_channel represents a one-to-one
mapping between a calling thread (represented by spdk_thread)
and an I/O device that the thread will perform I/O operations
on.

1 In our nvmf tgt implemention, we use the async
mode to delete the nvmf subsystem. However, when
we parse nvmf subsystem, we need to use the sync
function to delete the nvmf subsystem. Since if
there is error, we will call spdk_app_stop, thus
async functions will not be executed. It is
approved in my local test.
