For NUMA architecture, you may get performance drop if your NVMe
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.

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.
2 Add debug info in spdk_nvmf_delete_subsystem

connection to the session

Reason: In acceptor_poller_unregistered_event, we
directly call spdk_nvmf_check_pools and spdk_app_stop,
it will fail the memory check.
And function nvmf_delete_subsystem_poller_unreg will
not be called since we already call spdk_app_stop.

Move the NQN validation into the subsytem creation function, and fix the
allowed size to match the spec.
The spec is not clear about the allowed NQN size; for now, interpret it
as 223 bytes, including the null terminator (222 bytes of actual NQN
plus one terminator byte).

Build the now-generic nvmf_tgt app regardless of whether the RDMA
libraries are available.
The nvmf_tgt app Makefile still has to add the RDMA libraries to the
linker command, but otherwise it does not need to know anything about
the avilable transports.

This allows live configuration of the target, much like
the iSCSI target. More function calls will be added
over time.
Also, make the tests wait until the target is listening
on the RPC port to determine that the target is ready.

The NVMe over Fabrics target library now exposes a simple function call
that polls the acceptor once, and the application handles registration
of the poller.
Also rename the transport function pointers related to the acceptor so
they better reflect their purpose.

Make sure the trace history that is exported via shared memory is always
the same size, regardless of DPDK configuration.
Also removes the necessity of including DPDK headers from spdk/trace.h
(so we have to fix up other files to include what they use).

These can be simplified and merged into the subsystem.
Remove the concept of mappings from subsystems and replace
it with a list of hosts and ports. The host is optional -
not specifying a host means any host can connect.

The NVMf target is being refactored to split the RDMA transport-specific
code into its own file. Once this is complete, we should be able to
plug in other transports and build the NVMf target without any RDMA
dependency if desired.
To enable this, change the CONFIG option to RDMA; it still controls
whether the whole NVMf target is built for now, but once the RDMA
dependency is actually made optional, we will be able to build the
generic NVMf target code without libibverbs installed.
