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.

1 Rename this function and make it more meaninful, since
we have spdk_nvmf_session_connect which is used to link a
connection to the session
2 split spdk_nvmf_session_destruct.

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.

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.
