This introduces a new flag "secure" against the Type/TypeInfo
structs, and helpers to check this against the ObjectClass
struct.
If an object is considered to provide a security boundary to
protect against untrusted code, the "secure" flag must be
explicitly set to true.
If it is set to false, or left unset, this indicates that
the object does not intend to provide a security boundary.
Bugs related to this object class will be ineligible for
CVE assignment.

This introduces a new 'insecure-types' option for the 'compat'
argument that accepts three values
* accept: Allow any usage
* reject: Reject with an error reported
* warn: Allow any usage, with a warning reported
For historical compatibility it defaults to 'accept'.
The 'reject' and 'warn' values will take effect for any type
that has been explicitly marked insecure, or is lacking an
explicit declaration of its security status.
This new command line option is currently a no-op, but will
become functional as following patches enable the checks.

This wires up the accelerator creation code to apply the compat policy
security check. When multiple -accel options are given, normal fallback
logic applies. IOW, if one is rejected by the security check, it will
carry on to try the next accelerator until one passes the security
check.

When '-device help', 'device_add help' and 'info qdm' are used, report
the security status of each device.

Currently the QOM list method can filter on the abstract flag,
but extending the filtering to more variables requires a way
to pass in extra data items. This requires a refactoring of the
iterator to take a full struct as its opaque data item.

This adds:
* a new boolean 'secure' field to the type info returned by
qom-list-types, which will be set if the type provides a
security boundary
* a new boolean 'secure' parameter to the arguments of
qom-list-types, which can be used to filter types based
on their security status

The description of virtualization vs non-virtualization use
cases is a crude approximation of the security characteristics
of QEMU devices.
Document how QEMU can be probed to obtain information on the
security status of type classes, and how policies can be set
to inform or control their usage.

+Security status reporting
+'''''''''''''''''''''''''
+
+The QEMU project annotates types to explicitly state whether they are
+considered to provide a security boundary or not. For machine, accelerator
+and device types, only those annotated with the "secure" flag will be
+eligible for CVE assignment. Annotations will be extended to other backend
+and object types over time, to make their security status explicit.
+
+It is possible to control or identify the usage of types that do not offer
+an explicit security boundary using the ``insecure-types`` parameter to the
+``-compat`` argument, which accepts three values:
+
+ * accept: usage of any type will be permitted. This is the current
+ and historical default behaviour
+ * warn: usage of types not explicitly declared secure will result
+ in a warning message, but still be permitted.
+ * reject: usage of types not explicitly declared secure will result
+ in an error message, and will not be permitted.
+
+The compatibility policy will be honoured both at initial startup of
+QEMU and during any runtime alterations made with monitor commands.
+
+The status of any type class can be queried at runtime using the
+``qom-list-types`` command, whose returned information will flag any
+types declared as secure. The ``query-machines`` command will also
+reflect this same information for machine types.
+
+Machine type, accelerator and device security status can be queried
+using ``-machine help``, ``-accel help`` and ``-device help`` command
+line options respectively.
+
+Setting the ``.secure`` field to ``true`` in the ``TypeInfo``
+instance for an Object class, declares that the type aims to provide
+a security boundary.

The current DEFINE_MACHINE macro will declare machine type without any
explicit statement about the security status. As such the machine type
will be treated as implicitly insecure at runtime.
Introduce a new DEFINE_SECURE_MACHINE macro (with variants) that
allow code to make an explicit statement that the machine is treated
as secure. This should primarily be used for versioned machine types
that are intended to be used with KVM, though some others may warrant
a security declaration.
Use of the existing macros marks a machine as insecure, which is the
desired default for most machines servicing emulation use cases.
The same is done for the specialized i386 PC related macros.
