c04b2968a6 nvmf: enforce NQN validity at creation time
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).

c16ca1ade7 nvmf: remove app framework subsystem from library
It is no longer needed, since the nvmf_tgt app handles initialization
and shutdown.

0b252a7000 Revert "nvmf: only poll admin queue once every 10 ms"
This is causing issues during shutdown because the poller removal is not
synchronized with the rest of the cleanup path.

This reverts commit 7dfc5e922d.

7dfc5e922d nvmf: only poll admin queue once every 10 ms
This should enhance performance, since the hardware admin queue poll
function takes a mutex and should not be in the performance path.

5d8c94536a event: hide struct spdk_poller internals
This leaves more flexibility for future changes to the poller
representation without requiring API changes (after this one).

It also prevents the user from accidentally using poller fields in a
non-thread-safe way, since they can't be accessed directly anymore.

Move the ctrlr and io_qpair out of spdk_nvmf_subsystem, package them
as a new data structure. Union the direct and virtual mode namespaces.

89031c3e27 nvmf: move discovery subsystem creation to conf.c
It is not currently configurable, but this will allow us to make the
discovery subsystem have config options (e.g. which lcore to run on).

2b9d85c448 nvmf: Remove host.[ch] and port.[ch]
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.

Each subsystem will run on a single core, which is more than enough
to fully saturate a device and a NIC. For now, all subsystems
run on the master lcore.

NVMf does not have the concept of subsystem groups; the (former)
subsystem_grp files really contain structures and functions related to
individual subsystems.
