These were repeated a few different places, so pull them into a common
header file.

ad063db506 nvmf: apply const to several char * arguments
These strings are not modified by the functions they are passed to, so
they can be const char *.

1cbbfb86fa nvmf: Make cntlid globally unique.
The code doesn't actually use this property of cntlid
for anything yet, but we will need it later.

6ca517d460 nvmf: split subsystem lookup from host check
This allows us to print better error messages when connecting to a
subsystem that exists but does not allow a specific host.

Additionally, we can now return the correct error code for a host that
is not allowed.

b43db69a44 nvmf: Remove spdk_nvmf_transport from public API
The details of the structure were removed earlier, but
now remove all references even to a pointer to the
structure. The user can refer to transports by their
string name.

This is a step toward abstracting away the definition

fd6ebca7a8 nvmf: only save PCI address in direct ctrlr data
The NVMe over Fabrics target was storing the PCI device pointer for each
direct-mode controller, but it only really needs the PCI address, which
is exposed via the get_nvmf_subsystems RPC.

Also update the same code path to use the new spdk_pci_device_get_addr()
function for brevity.

1e6ffa0394 nvmf: Add a public API header
This changes as little code as possible while still creating
a single public API header. This enables future clean up
of the public API and clarification of the exposed
concepts.
