Running "install_headers" in the Linux source tree is fairly
unfriendly as out-of-tree builds will start complaining about the
kernel source being non-pristine. As we have a temporary directory for
the install we should also do the build step here. So now we have:
$tmpdir/
$blddir/
$hdrdir/

For union types, the tag member is known only after .check().
We used to code this in a simple way: QAPISchemaVariants attribute
.tag_member was None for union types until .check().
Since this complicated typing, recent commit "qapi/schema: fix typing
for QAPISchemaVariants.tag_member" hid it behind a property.
The previous commit lets us treat .tag_member just like the other
attributes that become known only in .check(): declare, but don't
initialize it in .__init__().

QAPISchemaVariants.check()'s code is almost entirely conditional on
union vs. alternate type.
Move the conditional code to QAPISchemaBranches.check() and
QAPISchemaAlternatives.check(), where the conditions are always
satisfied.
Attribute QAPISchemaVariants.tag_name is now only used by
QAPISchemaBranches. Move it there.

QAPISchemaVariants represents either a union type's branches, or an
alternate type's alternatives. Much of its code is conditional on
which one it actually is.
Create QAPISchemaBranches for branches, and QAPISchemaAlternatives for
alternatives, both subtypes of QAPISchemaVariants.
Replace QAPISchemaVariants by one of them where possible. Keep it
only where we actually deal with either of them.
QAPISchemaVariants.__init__() takes @tag_name and @tag_member, where
exactly one must be None: @tag_name for alternatives, @tag_member for
branches. Let QAPISchemaBranches.__init__() take just @tag_name, and
QAPISchemaAlternatives.__init__() take just @tag_member.
A later patch will move the conditional code to the subtypes.

We pass a ResetType argument to the Resettable class enter phase
method, but we don't pass it to hold and exit, even though the
callsites have it readily available. This means that if a device
cared about the ResetType it would need to record it in the enter
phase method to use later on. We should pass the type to all three
of the phase methods to avoid having to do that.
This coccinelle script adds the ResetType argument to the hold and
exit phases of the Resettable interface.
The first part of the script (rules holdfn_assigned, holdfn_defined,
exitfn_assigned, exitfn_defined) update implementations of the
interface within device models, both to change the signature of their
method implementations and to pass on the reset type when they invoke
reset on some other device.
The second part of the script is various special cases:
* method callsites in resettable_phase_hold(), resettable_phase_exit()
and device_phases_reset()
* updating the typedefs for the methods
* isl_pmbus_vr.c has some code where one device's reset method directly
calls the implementation of a different device's method

This script runs QEMU to obtain compat_props of machines and default
values of different types of drivers to produce comparison table. This
table can be used to compare machine types to choose the most suitable
machine or compare binaries to be sure that migration to the newer version
will save all device properties. Also the json or csv format of this
table can be used to check does a new machine affect the previous ones by
comparing tables with and without the new machine.
Default values (that will be used without machine compat_props) of
properties are needed to fill "holes" in the table (one machine has
the property but another machine not. For instance, 2.12 machine has
`{ "EPYC-" TYPE_X86_CPU, "xlevel", "0x8000000a" }`, but compat_pros of
3.1 machine doesn't have it. Thus, to compare these machines we need to
get unknown value of "EPYC-x86_64-cpu-xlevel" for 3.1 machine. These
unknown values in the table are called "holes". To get values for these
"holes" the script uses list of appropriate methods.)
Notes:
* Some init values from the devices can't be available like properties
from virtio-9p when configure has --disable-virtfs. This situations will
be seen in the table as "unavailable driver".
* Default values can be obtained in an unobvious way, like x86 features.
If the script doesn't know how to get property default value to compare
one machine with another it fills "holes" with "unavailable method". This
is done because script uses whitelist model to get default values of
different types. It means that the method that can't be applied to a new
type that can crash this script. It is better to get an "unavailable
driver" when creating a new machine with new compatible properties than
to break this script. So it turns out a more stable and generic script.
* If the default value can't be obtained because this property doesn't
exist or because this property can't have default value, appropriate
"hole" will be filled by "unknown property" or "no default value"
* If the property is applied to the abstract class, the script collects
default values from all child classes and prints all these classes
* Raw table (--raw flag) should be used with json/csv parameters for
scripts and etc. Human-readable (default) format contains transformed
and simplified values and it doesn't contain lines with the same values
in columns

./scripts/compare-machine-types.py --mt pc-q35-6.2 pc-q35-7.1
