Intel copyrights were not added to files where Intel either had
no contribution ot the contribution lacked substance (ie license

Note that several files in this patch didn't end the license/(c)

In SPDK, declarations have the return type on the same line. Definitions
have the return type on a separate line. Astyle has an option for
enforcing this. Unfortunately, it seems to have two bugs:
1) It doesn't work correctly at all on C++ files.
2) It often fails on functions that return enums, or long type names
Deal with 1) by adjusting the check_format.sh script to only tell astyle
to fix return type line breaks for C files and not C++. Deal with 2) by
adding a few typedefs to work around the problem.

DPDK CFLAGS get put into CFLAGS in mk/cc.flags.mk,
which for system package installed DPDK will include
extra paths like /usr/include/<arch-3-tuple>/dpdk.
If a Makefile adds its own CFLAGS before including
the .mk fragment that pulls in these CFLAGS, we won't
actually get those cc.flags.mk applied since they
are defined with ?=.
This may need to be revisited - using ?= for these
has evolved through several iterations of our SPDK
configured flag files - starting with commit
08ec96eb. But for now, let's just fix these few
Makefiles.

Many open source projects have moved to using SPDX identifiers
to specify license information, reducing the amount of
boilerplate code in every source file. This patch replaces
the bulk of SPDK .c, .cpp and Makefiles with the BSD-3-Clause
identifier.
Almost all of these files share the exact same license text,
and this patch only modifies the files that contain the
most common license text. There can be slight variations
because the third clause contains company names - most say
"Intel Corporation", but there are instances for Nvidia,
Samsung, Eideticom and even "the copyright holder".
Used a bash script to automate replacement of the license text
with SPDX identifier which is checked into scripts/spdx.sh.

Please use SPDK_VIRTIO_BLK_TRANSPORT_REGISTER to register the transport.
Transports can use virtio_blk_process_request() to process the
incoming I/O from their queues.
virtio_blk_create_transport RPC was added to create one of the
registered transports, possibly with custom JSON arguments.
Added 'transport' argument to vhost_create_blk_controller RPC,
to specify which transport should create the controller.
By default the vhost_user_blk transport is used.

What was previously called vhost_dev_install_rte_compat_hooks()

This enables us to write more advanced unit tests for vhost.
Instead of mocking low-level rte_vhost APIs, we could

create vhost devices and sessions without any actual

With all the pieces in place we can finally remove
the legacy cross thread messages from vhost.
We replace spdk_vhost_allocate_reactor() with
spdk_vhost_get_poll_group(). The returned poll_group
has to be passed to spdk_vhost_session_send_event(),
where it will be assigned to the session. After the
session it started, that poll group will be used for
all the internal vhost cross-thread messaging.

vring notification mechanism is transport-specific. At present, vhost
dataplane code in `lib/vhost/vhost.c` triggers guest notifications with
`eventfd_write()` system call. But this is an AF_UNIX specific
notification mechanism. This patch replaces `eventfd_write()` with the
existing generic `rte_vhost_vring_call()` function that is part of
DPDK's librte_vhost public API.
`rte_vhost_vring_call()` takes a vring_idx as an argument to associate
the `struct spdk_vhost_virtqueue` instance with the relevant `struct
vhost_virtqueue` instance. We introduce a new `vring_idx` field in
`struct spdk_vhost_virtqueue` to enable this association. This field is
initialized in `start_device()`. In addition, a stub for
`rte_vhost_vring_call()` is added in the vhost unit test file.
SPDK's internal `rte_vhost` copy will not be updated in order to support
the virtio-vhost-user transport. However, an `rte_vhost_vring_call()`
function is introduced in SPDK's `rte_vhost` in order to have a solid
API. This function is just a wrapper of `eventfd_write()`.

We used to rely on lcore >= 0 for sessions that are
started (have their pollers running) and in order to
prevent data races, that lcore field had to be set from
the same thread that runs the pollers, directly after
registering/unregistering them. The lcore was always
set to spdk_env_get_current_core(), but we won't be able
to use an equivalent get_current_poll_group() function
after we switch to poll groups. We will have a poll group
object only inside spdk_vhost_session_send_event() that's
called from the DPDK rte_vhost thread.
In order to change the lcore field (or a poll group one)
from spdk_vhost_session_send_event(), we'll need a separate
field to maintain the started/stopped status that's only
going to be modified from the session's thread.

DPDK 19.05+ gives us an ability to pre or post-process
any single vhost-user message. The user can either perform
additional actions upon some generic events, or can
implement handling for brand new message types that
rte_vhost doesn't even know about.
In order to smoothly switch to the upstream rte_vhost
and drop our internal copy, we introduce an SPDK wrapper
function to register SPDK-specific message handlers. For
DPDK 19.05+ this will use the new rte_vhost API to
register those message handlers, and for older DPDKs
this function simply won't do anything - as w assume the
internal rte_copy already contains all the necessary
changes and does not need any "external" hooks.
For now we use the message handlers to stop the vhost
device and wait for any pending DMA ops before letting
rte_vhost to process the SET_MEM_TABLE message and unmap
the current shared memory.

It's disabled by default, so no functionality is changed yet.
The intention is to use the upstream rte_vhost from DPDK,
which - starting from DPDK 19.05 - is finally capable of
running with storage device backends.
SPDK still requires a lot of changes in order to support
that upstream version, but the most fundamental change is
dropping vhost-nvme support. It'll remain usable only with
the internal rte_vhost copy and with the upstream rte_vhost
it simply won't be compiled. This allows us at least to
compile with that upstream rte_vhost, where we can pursue
adding the full integration.

Adapted our custom rte_vhost APIs to the upstream DPDK

This will potentially allow us to remove our internal
rte_vhost copy.
rte_vhost_set_vhost_vring_last_idx() was renamed to
rte_vhost_set_vring_base() and the last vring indices
have to be acquired with a newly introduced rte_vhost_get_vring_base()
rather than rte_vhost_get_vhost_vring().
This is only a refactor, no functionality is changed.

With all the patches in place, we can finally
enable having more than one simultaneous sessions
to a single vhost device.
This patch adds a unique id to the session structure,
similar to the one in a vhost device and also fills in
the implementation holes in foreach_session().
Vhost-NVMe can support only one session per device
and now has an additional check that prevents it from
starting more than one at a time.
Vhost-SCSI also has the same check now since it needs
additional work on the lcore assignment policy. The
check will be removed once the required work is done.

It's sessions that are tied with the lcores now.
This makes the vhost devices accessible by any
thread that only locks the global vhost mutex.
The mechanism used for external device events was
refactored to serve for foreach_session() API.
Additionally, since we don't want to handle cases
where the entire vhost device gets removed while
an asynchronous foreach_session chain is pending,
a new per-vdev counter of pending async operations
was added. We'll fail the device removal request
if there are any pending operations. Eventually
we would like the device removal to be asynchronous,
but that's a todo for later.
The external events are still there, although
they only lock the mutex and call the provided
function now.
