70a0bc3096 bdev: add bdev_io optimizations
First, improve packing of spdk_bdev_io.  Move any
fields which must be zeroed into the first cacheline.
Also change type and status from enums (needing 4 bytes)
to int16_t which is still a far bigger range than
needed.

Next, modify spdk_bdev_get_io to only zero the
first cacheline (actually a bit less).

SPDK_BDEV_IO_TYPE_INVALID is also added, making it
explicit that 0 is an invalid value for the IO type.
Previously this was somewhat inferred.

There are still additional improvements that can
be made to this area - primarily combining
spdk_bdev_get_io() and spdk_bdev_io_init() into
a single function.

5d1a206663 vhost: added API to call external spdk_events on vdev reactor
The next step towards fixing synchronization issues between RPC and
vhost controller reactor.

The general idea is to hide spdk_vhost_dev_find declaration, so that
vdev-related functions can't be (incorrectly) called from outside of
the vhost controller reactor. The vdev pointer should only be acquired
via spdk_vhost_call_external_event.

5b4b66bab9 nvmf: move admin processing to ctrlr.c
Now that the discovery controller is using the common admin command
functions, move all of them into the common ctrlr.c file.

This also eliminates the subsystem ops, which are now just direct calls.

99f838a36a nvme: add support for NS Optimal IO Boundary
An optional field was added in NVMe 1.3 to indicate the optimal I/O
boundary that should not be crossed for best performance.  This is
equivalent to the existing Intel-specific stripe size quirk.

Add support for the new NOIOB field and move the current quirk-based
code so it is updated in nvme_ns_identify_update().

1d304bc5d8 nvmf: Rename spdk_nvmf_conn to spdk_nvmf_qpair
Match the terminology used in the NVMe-oF specification,
which is queue pair. For the RDMA transport, this maps to
an RDMA queue pair, but may map to other things for other
transports. It still is logically a "connection" from
a networking sense.

03788f93df nvmf: Rename spdk_nvmf_session to spdk_nvmf_ctrlr
This is just a rename - the functionality hasn't changed.
Use the same terminology as the specification (which is controller)
so those familiar with the specification can more easily
approach the code base.

This is still conceptually equivalent to a "session" in the
networking sense.
