ebea4dd660 virtio_blk: add hotplug support
It can divide to two parts:
1, UIO driver - sigbus error handling and uevent
process.
2, VFIO - request notify handling.

sigbus error process is in previous patch.

e4070ee0e0 so_ver: increase all major versions
To allow SO_MINOR updates on LTS for the whole year it is supported,
the major version for all components needs to be increased.
This is to prevent scenario where two versions exists with matching
versions, but conflicting ABI.
Ex. Next SPDK release adds an API call increasing the minor version,
then LTS needs just a subset of those additions.

Increasing major so version after LTS, allows the quarterly releases
to update versions as needed. Yet allowing LTS to increase minor
version separately.

Disabled test for increasing SO version without ABI change, as
that is goal of this patch. This check shall be removed with SPDK 21.04
release.

This patch:
- increases SO_VER by 1 for all components
- resets SO_MINOR to 0 for all components
- removes suppressions for ABI tests

4c890c3160 virtio: add transitional virtio device support
SPDK virtio driver does not support the virtio legacy
device but it's ok for the modern and transitional
device. So update the probe function.

From the spec:
Transitional PCI Device ID Virtio Device
0x1000 network card
0x1001 block device
0x1002 memory ballooning (traditional)
0x1003 console
0x1004 SCSI host
0x1005 entropy source
0x1009 9P transport

Transitional Device: a device supporting both drivers conforming to
modern specification, and allowing legacy drivers.

6bd7bd0da2 vhost: deprecate internal vhost library support
The internal vhost library is used when DPDK's version
is older than 19.05 and the experiemntal vhost nvme
target.

For the CONFIG_INTERNAL_VHOST_LIB option, SPDK doesn't
enable this option by default over one year and CI
doesn't cover it either, so we may remove it with
this release.

As for the vhost-nvme target, since we are developing
a new vfio-user target solution, it's OK for us to remove
it now.

initialization, it will enter the bdev destruction process
which call the modern_destruct_dev function and hw will
be released during the process. So we will encounter the
problem of hw being released twice.

Our internal rte_vhost lib requires SET_VRING_ADDR to
flush a pending SET_MEM_TABLE. On the other hand, the
upstream rte_vhost will invalidate the entire queue
upon receiving SET_VRING_ADDR message, so we mustn't
send it at runtime. Both behaviors are strictly
implementation specific, but this message isn't needed
by the spec, so send it only if vhost was compiled

e67743162f virtio/user: minor cleanup
Make struct vhost_user_msg match the format defined in
the vhost-user spec. The custom additions were inhereted
from DPDK, but SPDK never made use of them. Also replace
direct sizeof(*msg) usages with a handy macro that was
already there. Finally add a VHOST_USER prefix to the
VHOST_MEMORY_MAX_NREGIONS #define.

148eda65c1 virtio: don't reinitialize entire virtqueues on mem hotplug
One of the messages we send on memory hotplug event is
SET_VRING_BASE, which tells vhost e.g. the position in
a vring it should start processing requests from. Sending
this message with any outstanding I/O could cause that
I/O to be never processed as it could be at a vring
position that won't be practically polled.

To fix the above, we don't send SET_VRING_BASE message
on memory hotplug event anymore since it's completely
unnecessary. It was sent together with a couple other
messages that would reinitialize the vring, but we know
vrings occupy a memory buffer that won't be hotremoved
during vring lifetime. We also know that vring GPAs will
never change. Hence we can initialize the vrings just
once on device start now.

We still need to send SET_VRING_ADDR after updating the
memory table, as rte_vhost depends on it to apply that
new memory table. Luckily, this single message doesn't
cause us any trouble.

8c4ed83b49 vtophys: add length parameter to the vtophys function
This follows the same trend as the mem_map APIs.

Currently, most of the spdk_vtophys() callers manually
detect physically noncontiguous buffers to split them
into multiple physically contiguous chunks. This patch
is a first step towards encapsulating most of that logic
in a single place - in spdk_vtophys() itself.

This patch doesn't change any functionality on its own,
it only extends the API.

65165d795d virtio: fix vq init error handling
We didn't handle vq alloc or init failure, because
queues are initialized all at once on device init and
if one vq fails, all of them are to be destroyed.

This behavior is really unintuitive, and with the
latest changes we have a possible segfault scenario.
(We could spdk_dma_free() a buffer that failed to
allocate).

It is now required that the queue allocation function
cleans up after itself.

It is required by the vhost-user spec. Rte_vhost doesn't check

might (and should) reject our GET_CONFIG requests right now.

As a part of this feature, we should also check the same
flag before sending GET/SET_CONFIG messages to respect those
devices that really don't implement F_CONFIG. This is done
in a separate patch.
