This is a very basic example app that shows how to
use the SPDK NVMe driver API for basic enumeration and
I/O operations.

The variable cur could be null, so if we use do while

The conventional rule for returning errno is negative, hence there is no
need to modify caller's code to adjust this NVMe library.

If we just pass NULL to rdma_create_qp, it will do
the right thing.

This enables SPDK_NVMF_BUILD_ETC to be moved out of the library as well,

SPDK_NVMF_BUILD_ETC will be cleaned up in another commit; it is
currently used both in the lib and in nvmf_tgt.

There is only a single global g_nvmf_tgt that can be passed to this
function, so remove the parameter and use the global directly.

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.

All source files will now depend on config.h, which is generated based
on the defaults in CONFIG and the command line arguments passed to make.
This ensures that any configuration changes, including on the command
line, cause a full rebuild.
