These were only intended for testing and should be replaced by a virtual
blockdev that can be layered on top of any kind of bdev.

connection) to 127.0.0.1 (accept only connections from the local host).

If AcceptorPollRate is configured in configuration
file, the default value used will be given by
ACCEPT_TIMEOUT_US. So change the default value, it
can solve the performance degradation issue of
nvmf target.

This patch also drops support for automatically unbinding
devices from the kernel - run scripts/setup.sh first.
Our generic pci interface is now hidden behind include/spdk/pci.h
and implemented in lib/util/pci.c. We no longer wrap the calls
in nvme_impl.h or ioat_impl.h. The implementation now only uses
DPDK and the libpciaccess dependency has been removed. If using
a version of DPDK earlier than 16.07, enumerating devices
by class code isn't available and only Intel SSDs will be
discovered. DPDK 16.07 adds enumeration by class code and all
NVMe devices will be correctly discovered.

Users can specify the core for each subsystem and the acceptor listen routine
to run on different cores for performance consideration.

can interoperate with the Linux and Windows standard iSCSI

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.

Change the Port configuration file entries to a new format:
[Port1]
Listen <transport> <address>:<service>
Initially, this still only supports RDMA, but the new format will allow
specifying other transports once they are added.

Multiple NVMe controllers within a subsystem does not work correctly,
since we would need to virtualize the controller data, namespace IDs,
and so on. For now, only allow pass-through mapping of a single NVMe
controller per subsystem.

The section is really defining a subsystem as defined
by the NVMf specification. There does not appear to be
any need for a group of subsystems.
This change only updates the configuration file. It does
not remove all references to a subsystem group from
the code.

The specification refers to this concept as a Host,
so use that term. This only changes the configuration
file usage. Initiator groups are still referenced in
the code and will be removed later.
