Adding check for `while` and `for` statements, which condition has more than
one line.
The former checkpatch.pl can check `if` statement, which condition has more
than one line, whether block misses brace round, like this:
'''
if (cond1 ||
cond2)
statement;
'''
But it doesn't do the same check for `for` and `while` statements.
Using `(?:...)` instead of `(...)` in regex pattern catch.
Because `(?:...)` is faster and avoids unwanted side-effect.

There is already 'device-list-properties' which does most of the job,
however it does not handle everything returned by qom-list-types such
as machines as they inherit directly from TYPE_OBJECT and not TYPE_DEVICE.
It does not handle abstract classes either.
This adds a new qom-list-properties command which prints properties
of a specific class and its instance. It is pretty much a simplified copy
of the device-list-properties handler.
Since it creates an object instance, device properties should appear
in the output as they are copied to QOM properties at the instance_init
hook.
This adds a object_class_property_iter_init() helper to allow class
properties enumeration uses it in the new QMP command to allow properties
listing for abstract classes.

This patch fixes an incorrect behavior when the -kernel argument has been
specified without -bios. In this case the kernel was loaded twice. At address
32M as a raw image and afterwards by load_elf/load_uimage at the
corresponding load address. In this case the region for the device tree and
the raw kernel image may overlap.
The patch fixes the behavior by loading the kernel image once with
load_elf/load_uimage and skips loading the raw image.
When here do not use bios_name/size for the kernel and use a more generic
name called payload_name/size.

handle the dtb only within the first 64MB. Add a comment to

Move the remaining comment into macio.c for reference, then remove the
macio_init() function and instantiate the macio devices for both Old World
and New World machines via qdev_init_nofail() directly.

Also switch macio_newworld_realize() over to use it rather than using the pic_mem
memory region directly.
Now that both Old World and New World macio devices no longer make use of the
pic_mem memory region directly, we can remove it.

This is needed before the next patch because the target-dependent kvm stub
uses the existing kvm_openpic_connect_vcpu() declaration, making it impossible
to move the device-specific declarations into the same file without breaking
ppc-linux-user compilation.
