Interaction with vmnet.framework in different modes
differs only on configuration stage, so we can create
common `send`, `receive`, etc. procedures and reuse them.

vmnet.framework dependency is added with 'vmnet' option
to enable or disable it. Default value is 'auto'.
used vmnet features are available since macOS 11.0,
but new backend can be built and work properly with
subset of them on 10.15 too.

Commit 747421e949 ("Implements Backend
Program conventions for vhost-user-scsi") introduced fd-passing support
as part of implementing the vhost-user backend program conventions.
When fd passing is used the UNIX domain socket path is NULL and we must
not call unlink(2).
The unlink(2) call is necessary when the listen socket, lsock, was
created successfully since that means the UNIX domain socket is visible
in the file system.

virtio_queue_host_notifier_read() tends to read pending event
left behind on ioeventfd in the vhost_net_stop() path, and
attempts to handle outstanding kicks from userspace vq handler.
However, in the ctrl_vq handler, virtio_net_handle_mq() has a
recursive call into virtio_net_set_status(), which may lead to
segmentation fault as shown in below stack trace:

For now, temporarily disable handling MQ request from the ctrl_vq
userspace hanlder to avoid the recursive virtio_net_set_status()
call. Some rework is needed to allow changing the number of
queues without going through a full virtio_net_set_status cycle,
particularly for vhost-vdpa backend.
This patch will need to be reverted as soon as future patches of
having the change of #queues handled in userspace is merged.

The name vhost_vdpa_one_time_request() was confusing. No
matter whatever it returns, its typical occurrence had
always been at requests that only need to be applied once.
And the name didn't suggest what it actually checks for.
Change it to vhost_vdpa_first_dev() with polarity flipped
for better readibility of code. That way it is able to
reflect what the check is really about.
This call is applicable to request which performs operation
only once, before queues are set up, and usually at the beginning
of the caller function. Document the requirement for it in place.

The vhost_vdpa_one_time_request() branch in
vhost_vdpa_set_backend_cap() incorrectly sends down
ioctls on vhost_dev with non-zero index. This may
end up with multiple VHOST_SET_BACKEND_FEATURES
ioctl calls sent down on the vhost-vdpa fd that is
shared between all these vhost_dev's.
To fix it, send down ioctl only once via the first
vhost_dev with index 0. Toggle the polarity of the
vhost_vdpa_one_time_request() test should do the
trick.

The cause for the assert failure is due to that the vhost_dev index
for the ctrl vq was not aligned with actual one in use by the guest.
Upon multiqueue feature negotiation in virtio_net_set_multiqueue(),
if guest doesn't support multiqueue, the guest vq layout would shrink
to a single queue pair, consisting of 3 vqs in total (rx, tx and ctrl).
This results in ctrl_vq taking a different vhost_dev group index than
the default. We can map vq to the correct vhost_dev group by checking
if MQ is supported by guest and successfully negotiated. Since the
MQ feature is only present along with CTRL_VQ, we ensure the index
2 is only meant for the control vq while MQ is not supported by guest.

The specification for VHOST_USER_ADD/REM_MEM_REG messages is unclear
in several points, which has led to clients having incompatible
implementations. This changes the specification to be more explicit
about them:
* VHOST_USER_ADD_MEM_REG is not specified as receiving a file
descriptor, though it obviously does need to do so. All
implementations agree on this one, fix the specification.
* VHOST_USER_REM_MEM_REG is not specified as receiving a file
descriptor either, and it also has no reason to do so. rust-vmm does
not send file descriptors for removing a memory region (in agreement
with the specification), libvhost-user and QEMU do (which is a bug),
though libvhost-user doesn't actually make any use of it.
Change the specification so that for compatibility QEMU's behaviour
becomes legal, even if discouraged, but rust-vmm's behaviour becomes
the explicitly recommended mode of operation.
* VHOST_USER_ADD_MEM_REG doesn't have a documented return value, which
is the desired behaviour in the non-postcopy case. It also implemented
like this in QEMU and rust-vmm, though libvhost-user is buggy and
sometimes sends an unexpected reply. This will be fixed in a separate
patch.
However, in postcopy mode it does reply like VHOST_USER_SET_MEM_TABLE.
This behaviour is shared between libvhost-user and QEMU; rust-vmm
doesn't implement postcopy mode yet. Mention it explicitly in the
spec.
* The specification doesn't mention how VHOST_USER_REM_MEM_REG
identifies the memory region to be removed. Change it to describe the
existing behaviour of libvhost-user (guest address, user address and
size must match).

Implement zero copy send on nocomp_send_write(), by making use of QIOChannel
writev + flags & flush interface.
Change multifd_send_sync_main() so flush_zero_copy() can be called
after each iteration in order to make sure all dirty pages are sent before
a new iteration is started. It will also flush at the beginning and at the
end of migration.
Also make it return -1 if flush_zero_copy() fails, in order to cancel
the migration process, and avoid resuming the guest in the target host
without receiving all current RAM.
This will work fine on RAM migration because the RAM pages are not usually freed,
and there is no problem on changing the pages content between writev_zero_copy() and
the actual sending of the buffer, because this change will dirty the page and
cause it to be re-sent on a next iteration anyway.
A lot of locked memory may be needed in order to use multifd migration
with zero-copy enabled, so disabling the feature should be necessary for
low-privileged users trying to perform multifd migrations.

Since d48c3a0445 ("multifd: Use a single writev on the send side"),
sending the header packet and the memory pages happens in the same
writev, which can potentially make the migration faster.
Using channel-socket as example, this works well with the default copying
mechanism of sendmsg(), but with zero-copy-send=true, it will cause
the migration to often break.
This happens because the header packet buffer gets reused quite often,
and there is a high chance that by the time the MSG_ZEROCOPY mechanism get
to send the buffer, it has already changed, sending the wrong data and
causing the migration to abort.
It means that, as it is, the buffer for the header packet is not suitable
for sending with MSG_ZEROCOPY.
In order to enable zero copy for multifd, send the header packet on an
individual write(), without any flags, and the remanining pages with a
writev(), as it was happening before. This only changes how a migration
with zero-copy-send=true works, not changing any current behavior for
migrations with zero-copy-send=false.

For CONFIG_LINUX, implement the new zero copy flag and the optional callback
io_flush on QIOChannelSocket, but enables it only when MSG_ZEROCOPY
feature is available in the host kernel, which is checked on
qio_channel_socket_connect_sync()
qio_channel_socket_flush() was implemented by counting how many times
sendmsg(...,MSG_ZEROCOPY) was successfully called, and then reading the
socket's error queue, in order to find how many of them finished sending.
Flush will loop until those counters are the same, or until some error occurs.
Notes on using writev() with QIO_CHANNEL_WRITE_FLAG_ZERO_COPY:
1: Buffer
- As MSG_ZEROCOPY tells the kernel to use the same user buffer to avoid copying,
some caution is necessary to avoid overwriting any buffer before it's sent.
If something like this happen, a newer version of the buffer may be sent instead.
- If this is a problem, it's recommended to call qio_channel_flush() before freeing
or re-using the buffer.
2: Locked memory
- When using MSG_ZERCOCOPY, the buffer memory will be locked after queued, and
unlocked after it's sent.
- Depending on the size of each buffer, and how often it's sent, it may require
a larger amount of locked memory than usually available to non-root user.
- If the required amount of locked memory is not available, writev_zero_copy
will return an error, which can abort an operation like migration,
- Because of this, when an user code wants to add zero copy as a feature, it
requires a mechanism to disable it, so it can still be accessible to less
privileged users.

Add flags to io_writev and introduce io_flush as optional callback to
QIOChannelClass, allowing the implementation of zero copy writes by
subclasses.
How to use them:
- Write data using qio_channel_writev*(...,QIO_CHANNEL_WRITE_FLAG_ZERO_COPY),
- Wait write completion with qio_channel_flush().
Notes:
As some zero copy write implementations work asynchronously, it's
recommended to keep the write buffer untouched until the return of
qio_channel_flush(), to avoid the risk of sending an updated buffer
instead of the buffer state during write.
As io_flush callback is optional, if a subclass does not implement it, then:
- io_flush will return 0 without changing anything.
Also, some functions like qio_channel_writev_full_all() were adapted to
receive a flag parameter. That allows shared code between zero copy and
non-zero copy writev, and also an easier implementation on new flags.

As above error message suggests, 'struct __kernel_timespec' was already
defined by liburing/compat.h.
Fix alpine CI by adding test to disable liburing in configure step if a
redefinition happens between linux/errqueue.h and liburing/compat.h.
[dgilbert: This has been fixed in Alpine issue 13813 and liburing]

Various methods in the migration test call 'query_migrate' to fetch the
current status and then access a particular field. Almost all of these
cases expect the migration to be in a non-failed state. In the case of
'wait_for_migration_pass' in particular, if the status is 'failed' then
it will get into an infinite loop. By validating that the status is
not 'failed' the test suite will assert rather than hang when getting
into an unexpected state.

This validates that we correctly handle multifd migration success
and failure scenarios when using TLS with x509 certificates. There
are quite a few different scenarios that matter in relation to
hostname validation, but we skip a couple as we can assume that
the non-multifd coverage applies to some extent.

Most of the multifd migration test logic is common with the rest of the
precopy tests, so it can use the helper without difficulty. The only
exception of the multifd cancellation test which tries to run multiple
migrations in a row.
