mirror: fix early wake from sleep due to aio
The mirror blockjob coroutine rate-limits itself by sleeping. The
coroutine also performs I/O asynchronously so it's important that the
aio callback doesn't wake the coroutine early as that breaks
rate-limiting.

mirror: fix throttling delay calculation
The throttling delay calculation was using an inaccurate sector count to
calculate the time to sleep. This broke rate-limiting for the block
mirror job.
Move the delay calculation into mirror_iteration() where we know how
many sectors were transferred. This lets us calculate an accurate delay
time.

osdep: initialize glib threads in all QEMU tools
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.

qom: Add check() argument to object_property_add_link()
There are currently three types of object_property_add_link() callers:
1. The link property may be set at any time.
2. The link property of a DeviceState instance may only be set before
realize.
3. The link property may never be set, it is read-only.
Something similar can already be achieved with
object_property_add_str()'s set() argument. Follow its example and add
a check() argument to object_property_add_link().
Also provide default check() functions for case #1 and #2. Case #3 is
covered by passing a NULL function pointer.

qom: Make QOM link property unref optional
Some object_property_add_link() callers expect property deletion to
unref the link property object. Other callers expect to manage the
refcount themselves. The former are currently broken and therefore leak
the link property object.
This patch adds a flags argument to object_property_add_link() so the
caller can specify which refcount behavior they require. The new
OBJ_PROP_LINK_UNREF_ON_RELEASE flag causes the link pointer to be
unreferenced when the property is deleted.
This fixes refcount leaks in qdev.c, xilinx_axidma.c, xilinx_axienet.c,
s390-virtio-bus.c, virtio-pci.c, virtio-rng.c, and ui/console.c.
Rationale for refcount behavior:
* hw/core/qdev.c
- bus children are explicitly unreferenced, don't interfere
- parent_bus is essentially a read-only property that doesn't hold a
refcount, don't unref
- hotplug_handler is leaked, do unref
* hw/dma/xilinx_axidma.c
- rx stream "dma" links are set using set_link, therefore they
need unref
- tx streams are set using set_link, therefore they need unref
* hw/net/xilinx_axienet.c
- same reasoning as hw/dma/xilinx_axidma.c
* hw/pcmcia/pxa2xx.c
- pxa2xx bypasses set_link and therefore does not use refcounts
* hw/s390x/s390-virtio-bus.c
* hw/virtio/virtio-pci.c
* hw/virtio/virtio-rng.c
* ui/console.c
- set_link is used and there is no explicit unref, do unref

qcow2: Fix fail path in realloc_refcount_block()
If qcow2_alloc_clusters() fails, new_offset and ret will both be
negative after the fail label, thus passing the first if condition and
subsequently resulting in a call of qcow2_free_clusters() with an
invalid (negative) offset parameter. Fix this by introducing a new label
"fail_free_cluster" which is only invoked if new_offset is indeed
pointing to a newly allocated cluster that should be cleaned up by
freeing it.
While we're at it, clean up the whole fail path. qcow2_cache_put()
should (and actually can) never fail, hence the return value can safely
be ignored (aside from asserting that it indeed did not fail).
Furthermore, there is no reason to give QCOW2_DISCARD_ALWAYS to
qcow2_free_clusters(), a mere QCOW2_DISCARD_OTHER will suffice.
Ultimately, rename the "fail" label to "done", as it is invoked both on
failure and success.

Intermittent issues have been seen where no serial input occurs. It
appears the pl011 gets in a state where the rx interrupt never fires
because the rx interrupt only asserts when crossing the fifo trigger
level. The fifo state appears to get out of sync when the pl011 is
re-configured. This combined with the rx timeout interrupt not being
modeled results in no more rx interrupts.
Disabling the fifo is the recommended way to clear the tx fifo in the
TRM (section 3.3.8). The behavior in this case for the rx fifo is
undefined in the TRM, but having fifo contents to be maintained during
configuration changes is not likely expected behavior. Reseting the

i386/acpi-build: support hotplug of VCPU with APIC ID 0xFF
Building on the previous patch, raise the maximal count of processor
objects / NTFY branches / CPON elements from 255 to 256. This allows the
VCPU with APIC ID 0xFF to be hotplugged.

i386/acpi-build: allow more than 255 elements in CPON
The build_ssdt() function builds a number of AML objects that are related
to CPU hotplug, and whose IDs form a contiguous sequence of APIC IDs.
(APIC IDs are in fact discontiguous, but this is the traditional
interface: build a contiguous sequence from zero up that covers all
possible APIC IDs.) These objects are:
- a Processor() object for each VCPU,
- a NTFY method, with one branch for each VCPU,
- a CPON package with one element (hotplug status byte) for each VCPU.
The build_ssdt() function currently limits the *count* of processor
objects, and NTFY branches, and CPON elements, in 0xFF (see the assignment
to "acpi_cpus"). This allows for an inclusive APIC ID range of [0..254].
This is incorrect, because the highest APIC ID that we otherwise allow a
VCPU to take is 255.
In order to extend the maximum count to 256, and the traversed APIC ID
range correspondingly to [0..255]:
- the Processor() objects need no change,
- the NTFY method also needs no change,
- the CPON package must be updated, because it is defined with a
DefPackage, and the number of elements in such a package can be at most
255. We pick a DefVarPackage instead.
We replace the Op byte, and the encoding of the number of elements.
Compare:
DefPackage := PackageOp PkgLength NumElements PackageElementList
DefVarPackage := VarPackageOp PkgLength VarNumElements PackageElementList
PackageOp := 0x12
VarPackageOp := 0x13
NumElements := ByteData
VarNumElements := TermArg => Integer
The build_append_int() function implements precisely the following TermArg
encodings (a subset of what the ACPI spec describes):
TermArg := DataObject
DataObject := ComputationalData
ComputationalData := ConstObj | ByteConst | WordConst | DWordConst
directly encoded in the function, with build_append_byte():
ConstObj := ZeroOp | OneOp
ZeroOp := 0x00
OneOp := 0x01
call to build_append_value(..., 1):
ByteConst := BytePrefix ByteData
BytePrefix := 0x0A
ByteData := 0x00 - 0xFF
call to build_append_value(..., 2):
WordConst := WordPrefix WordData
WordPrefix := 0x0B
WordData := ByteData[0:7] ByteData[8:15]
call to build_append_value(..., 4):
DWordConst := DWordPrefix DWordData
DWordPrefix := 0x0C
DWordData := WordData[0:15] WordData[16:31]
