If VIRTIO_NET_F_CTRL_VLAN is not negotiated, do not filter out all
VLAN-tagged packets but send them to the guest.

This fixes VLANs with OpenBSD guests (and probably NetBSD, too, because
the OpenBSD driver started as a port from NetBSD).

    acpi: make SSDT 1.0 spec compliant when possible
We are back to old encoding.
Signed-off-by: NMichael S. Tsirkin <mst@redhat.com>

The ACPI specification says:

The ASL compiler can emit two different AML opcodes for a Package
declaration, either PackageOp or VarPackageOp. For small, fixed-length
packages, the PackageOp is used and this opcode is compatible with ACPI
1.0. A VarPackageOp will be emitted if any of the following conditions
are true:
. The NumElements argument is a TermArg that can only be resolved at
runtime.
. At compile time, NumElements resolves to a constant that is larger than
255.
. The PackageList contains more than 255 initializer elements.
Note: The ability to create variable-sized packages was first introduced
in ACPI 2.0. ACPI 1.0 only allowed fixed-size packages with up to 255 elements.

So the spec seems to say a fixed value up to 255 must always
be used with PackageOp and not VarPackageOp, and some guests
(windows up to win2k8) seem to interpret it like this.

Let's do just this, choosing the encoding depending on
the number of elements.

Fixes 9bcc80cd
(i386/acpi-build: allow more than 255 elements in CPON).

The mirror blockjob coroutine rate-limits itself by sleeping.  The

The throttling delay calculation was using an inaccurate sector count to
calculate the time to sleep.  This broke rate-limiting for the block

Move the delay calculation into mirror_iteration() where we know how
many sectors were transferred.  This lets us calculate an accurate delay
time.

glib versions prior to 2.31.0 require an explicit g_thread_init() call
to enable multi-threading.

Failure to initialize threading causes glib to take single-threaded code
paths without synchronization.  For example, the g_slice allocator will
crash due to race conditions.

Fix this for all QEMU tool programs (qemu-nbd, qemu-io, qemu-img) by
moving the g_thread_init() call from vl.c:main() into a new
osdep.c:thread_init() constructor function.

thread_init() has __attribute__((constructor)) and is automatically
invoked by the runtime during startup.

We can now drop the "simple" trace backend's g_thread_init() call since
thread_init() already called it.

Note that we must keep coroutine-gthread.c's g_thread_init() call which
is located in a constructor function.  There is no guarantee for
constructor function ordering so thread_init() may only be called later.
