bc0867dcaf nvmf: move subsytem poller to nvmf_tgt app
The application is now entirely responsible for scheduling subsystem
pollers and sending events between threads.

9f2fc78e3f NVMf: Handle the memory leak issue of nvmf tgt
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.

c04b2968a6 nvmf: enforce NQN validity at creation time
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).

4ace96533d nvmf_tgt: build even if RDMA is disabled
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.

4c6e4d4963 nvmf: move acceptor poller into nvmf_tgt app

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.

3f80d55199 CONFIG: rename CONFIG_NVMF to CONFIG_RDMA
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.
