Named/Reserved{Field} definition uses PkgLength [1] encoding to specify
field length, however it doesn't include size of PkgLength field itself,
while other block objects that have explicit length of its body account
for PkgLength size while encoding it [2].
This special casing isn't mentioned in ACPI spec, but that's what 'iasl'
compiles NamedField to so add extra argument to build_prepend_pkg_length()
to allow it handle the case.

Adds for dynamic AML creation, which will be used
for piecing ASL/AML primitives together and hiding
from user/caller details about how nested context
should be closed/packed leaving less space for
mistakes and necessity to know how AML should be
encoded, allowing user to concentrate on ASL
representation instead.
For example it will allow to create AML like this:
init_aml_allocator();
...
Aml *scope = aml_scope("PCI0")
Aml *dev = aml_device("PM")
aml_append(dev, aml_name_decl("_ADR", aml_int(addr)))
aml_append(scope, dev);
...
free_aml_allocator();

Add a helper function for checking whether a bit is set in the guest
features for a vdev as well as one that works on a feature bit set.
Convert code that open-coded this: It cleans up the code and makes it

Add virtio_{add,clear}_feature helper functions for manipulating a
feature bits variable. This has some benefits over open coding:
- add check that the bit is in a sane range
- make it obvious at a glance what is going on
- have a central point to change when we want to extend feature bits
Convert existing code manipulating features to use the new helpers.

Makes sure that RSDP stays the same
/i.e. matches ACPI tables blob in source/

has been already shadowed by firmware.
Fix applies only to new machine types starting

machine types.

When the unplug operation happens, unplug request cb is called first.
And when guest OS finished handling unplug, unplug cb will be called

hot unplug will use it.

-global lets you set a nice booby-trap for yourself:
$ qemu-system-x86_64 -nodefaults -S -display none -usb -monitor stdio -global usb-mouse.usb_version=l
QEMU 2.1.94 monitor - type 'help' for more information
(qemu) device_add usb-mouse
Parameter 'usb_version' expects an int64 value or range
$ echo $?
1
Not nice. Until commit 3196270 we even abort()ed.
The same error triggers if you manage to screw up a machine type's
compat_props. To demonstrate, change HW_COMPAT_2_1's entry to
.driver = "usb-mouse",\
.property = "usb_version",\
.value = "1", \
Then run
$ qemu-system-x86_64 -usb -M pc-i440fx-2.1 -device usb-mouse
upstream-qemu: -device usb-mouse: Parameter 'usb_version' expects an int64 value or range
$ echo $?
1
One of our creatively cruel error messages.
Since this is actually a coding error, we *should* abort() here.
Replace the error by an assertion failure in this case.
But turn the fatal error into a mere warning when the faulty
GlobalProperty comes from the user. Looks like this:
$ qemu-system-x86_64 -nodefaults -S -display none -usb -monitor stdio -global usb-mouse.usb_version=l
QEMU 2.1.94 monitor - type 'help' for more information
(qemu) device_add usb-mouse
Warning: global usb-mouse.usb_version=l ignored (Parameter 'usb_version' expects an int64 value or range)
(qemu)
This is consistent with how we handle similarly unusable -global in
qdev_prop_check_globals().
You could argue that the error should make device_add fail. Would be
harder, because we're running within TypeInfo's instance_post_init()
method device_post_init(), which can't fail.
