239ba69c78 nvmf_tgt: decouple RPC ns list from subsystem internals
MAX_VIRTUAL_NAMESPACE will be removed from the public API, so use an
RPC-specific array size to remove its use in nvmf_tgt.

Also increase the number of namespaces accepted by the RPC call; this
does not actually allow more than MAX_VIRTUAL_NAMESPACE right now, since
the namespaces are still stored in a fixed-size array inside the
subsystem, but at least the RPC side is not limited by that size now.
In the future, we will make the subsystem namespace list dynamically
sized.

f4f3bef1cc nvmf: make sure nvmf target workable when it run as secondary porcess.
This patch do the following optimization:
1 when the nvmf target run as secondary process, the nvme probe will
  not call the probe callback function, which will skip the step to
  set up the ctx->found, so we set up it when we call attach callback.
2 when the nvmf target run as secondary process, every time when we try
  to probe one device, it will iterate all the attached devices and call
  the attach callback, for nvmf target, it will cause the overwrite of
  the nvme controller for the nvmf subsystem, so we need to compare the
  attached deivce with the device which we try to attach, if they are not
  the same one, just return.

bfe2897da3 nvmf,target: solve shutdown coredump issue
It is caused by this commit:
4163626c5cd310fa1c7fca2e02ccf41ffaf6d7f4

nvmf_tgt_delete_subsystem registers the poller
with function subsystem_delete_event.
subsystem_delete_event is called asynchronously,
the deletion should happen in this function.
Otherwise, with the current code,

g_subsystems_shutdown = true
TAILQ_EMPTY(&g_subsystems) = true
when subsystem_delete_event is firstly called.

If there are multiple subsystems, the logic is wrong.
Thus other subsystem will never be delete. since
we already execute shutdown_complete().

Also add related test scripts.
