David Hildenbrand 137974cea3 s390x/cpumodel: implement QMP interface "query-cpu-model-expansion" 
In order to expand CPU models, we create temporary cpus that handle the
feature/group parsing. Only CPU feature properties are expanded.

When converting the data structure back, we always fall back to the
static base CPU model, which is by definition migration-safe.

# This feature can help to reduce the migration traffic, by sending

# These types are mapped to the appropriate JSON type.

# @path: The path within the object model. There are two forms of supported
# paths--absolute and partial paths.
#
# Absolute paths are derived from the root object and can follow child<>
# or link<> properties. Since they can follow link<> properties, they
# can be arbitrarily long. Absolute paths look like absolute filenames
# and are prefixed with a leading slash.
#
# Partial paths look like relative filenames. They do not begin
# with a prefix. The matching rules for partial paths are subtle but
# designed to make specifying objects easy. At each level of the
# composition tree, the partial path is matched as an absolute path.
# The first match is not returned. At least two matches are searched
# for. A successful result is only returned if only one match is
# found. If more than one match is found, a flag is return to
# indicate that the match was ambiguous.
#
# @property: The property name to read
#
# Returns: The property value. The type depends on the property
# type. child<> and link<> properties are returned as #str
# pathnames. All integer property types (u8, u16, etc) are
# returned as #int.

#
# Dump guest's memory to vmcore. It is a synchronous operation that can take

#
# @paging: if true, do paging to get guest's memory mapping. This allows
# using gdb to process the core file.
#
# IMPORTANT: this option can make QEMU allocate several gigabytes
# of RAM. This can happen for a large guest, or a
# malicious guest pretending to be large.
#
# Also, paging=true has the following limitations:
#
# 1. The guest may be in a catastrophic state or can have corrupted
# memory, which cannot be trusted
# 2. The guest can be in real-mode even if paging is enabled. For
# example, the guest uses ACPI to sleep, and ACPI sleep state
# goes in real-mode
