This series refactor the qdev property code so the static
property system from qdev becomes a common QOM API that can be
used by any QOM type.

As an example, at the end of the series we use the new API at:
* check-qom-proplist unit test, to replace the hand-written
  getter and setter for the "sv" property
* target/i386/sev.c, to replace the instance properties
  registered using object_property_add_uint32_ptr()

I still want to make object_class_add_field_properties() the
recommended interface for registering QOM properties,
but this will be done in another series.

Changes v2 -> v3
----------------

* Patches were reordered

* New qom/qom.h header file
  (See "qom: Add new qom.h header")

* Fixed memory leak in the array property refactor from v2
  (See "qdev: Get rid of ArrayElementProperty struct")

* Made object_property_add_field() copy the Property struct
  passed as argument, to make the array property memory leak
  easier to fix
  (See "qdev: Make object_property_add_field() copy the Property struct")

* Both object_class_add_field_properties() and
  object_class_property_add_field() functions are available,
  but only object_class_property_add_field() are made public
  by this series.  object_class_add_field_properties() is
  used to implement device_class_set_props().
  (See "qom: object_class_property_add_field() function" &
  "qdev: Separate generic and device-specific property registration")

* Now object_class_property_add_field() will get a copy of the
  Property struct, to avoid tricks involving static variables
  in the FIELD_PROP macro.
  (See "qom: object_class_property_add_field() function")

* check-qom-proplist won't use object_property_add_field(),
  as it is an internal API and I don't want to make it a bad
  example to be followed.
  (See "tests: Use field property at check-qom-proplist test case")

* Property.qdev_prop_name is now Property.name_template, because
  it might be used outside qdev in case we make
  object_class_add_field_properties() public.
  (See "qdev: Rename Property.name to Property.name_template")

* New unit test for array property
  (See "tests: Add unit test for qdev array properties")

* Include sev patch for using class properties instead of
  object_property_add_uint32_ptr()
  (See "sev: Use class properties")

* FIELD_PROP macro is now inside field-property.h
  (See "qom: FIELD_PROP macro")

* DEFINE_PROP_* macros are now defined using PROP_*, not
  the other way around
  (See "qom: PROP_* macros")

Changes v1 -> v2
----------------

* Rename functions and source files to call the new feature
  "field property" instead of "static property"

* Change the API signature from an array-based interface similar
  to device_class_set_props() to a object_property_add()-like
  interface.

  This means instead of doing this:

    object_class_property_add_static_props(oc, my_array_of_props);

  properties are registered like this:

    object_class_property_add_field(oc, "property-name"
                                    PROP_XXX(MyState, my_field),
                                    prop_allow_set_always);

  where PROP_XXX is a PROP_* macro like PROP_STRING, PROP_BOOL,
  etc.

* Make Property.name optional.  Rename it to qdev_prop_name,
  and restrict its usage to qdev property tracking code.

* Make allow_set callback mandatory, to avoid ambiguity

* Big cleanup of array property code.  We don't need a custom
  release function for array elements anymore, because we don't
  need to save the property name in the Property struct anymore.

* Moved UUID property to qdev-properties-system, because
  it still has dependencies on qdev code

Paolo, do you have any objections to adding the field property
API in this series to QOM, considering the recent discussions
about long term plans for QOM properties?

Note that I still want to perform most of the changes in this
series, even if the code is kept inside `hw/core`.  Moving the
code to `qom` is just one extra step, but not essential.
