This is an optional parameter for int properties, which then show up as
enum properties.
Included fix: reset ID properties' enum items when the `items` parameter is `None`.
Example usage:
```python
import rna_prop_ui
# Add a regular int property.
rna_prop_ui.rna_idprop_ui_create(D.objects['Cube'], "test", default=123, min=-3, max=500)
# Change to an enum property with items (min/max are ignored).
rna_prop_ui.rna_idprop_ui_create(D.objects['Cube'], "test", default=0, min=-10, max=10, items=[("APPLES", "Apples", ""), ("ORANGES", "Oranges", "")])
# Switch back to regular int property.
rna_prop_ui.rna_idprop_ui_create(D.objects['Cube'], "test", default=1, min=0, max=10)
```

`PyArg_ParseTupleAndKeywords` does not initialize variable corresponding
to optional arguments that aren't passed by Python. Thanks to Germano for
initial investigation.
Add support for enum values in ID properties.
This is needed for the "Menu Switch" node implementation (#113445) which
relies on ID properties for the top-level modifier UI.
Enums items can optionally be added to the UI data of integer
properties. Each property stores a full set of the enum items to keep
things simple.
Enum items can be added to properties using the `id_properties_ui`
function in the python API. A detailed example can be found in the
`bl_pyapi_idprop.py` test.
There is currently no support yet for editing enum items through the UI.
This is because the "Edit Property" feature is implemented entirely
through a single operator (`WM_OT_properties_edit`) and its properties.
Buttons to add/remove/move items would be operators changing another
operator's properties. A refactor of the custom properties UI is likely
required to make this work.

New code exposing ID Pointers CustomProperties to the UI (b3c7f3c8a9)
would cause invalid data access when calling `as_dict()` on py-defined ID
pointers ID properties, since these have no ID type defined by default.
The code of `as_dict()` will now forcefully generate a valid ID type
value, either by using the type of the currently assigned ID, or falling
back to the Object ID type.
Found while opening some lighting production files from the Pets
Project.
Customprops to IDs are supported since years through code, but were
never exposed directly in the UI of customporperties.
This commit mainly:
* Adds a new `DATA_BLOCK` type to UI customprops types.
* Exposes the existing `id_type` settings to python API.

Listing the "Blender Foundation" as copyright holder implied the Blender
Foundation holds copyright to files which may include work from many
developers.
While keeping copyright on headers makes sense for isolated libraries,
Blender's own code may be refactored or moved between files in a way
that makes the per file copyright holders less meaningful.
Copyright references to the "Blender Foundation" have been replaced with
"Blender Authors", with the exception of `./extern/` since these this
contains libraries which are more isolated, any changed to license
headers there can be handled on a case-by-case basis.
Some directories in `./intern/` have also been excluded:
- `./intern/cycles/` it's own `AUTHORS` file is planned.
- `./intern/opensubdiv/`.
An "AUTHORS" file has been added, using the chromium projects authors
file as a template.
