This is similar to c4a2067130130d, but applies to the general UI and is only about single data-blocks. Here there was a similar problem: How can buttons pass the data they represent to operators? We currently resort to ugly ad-hoc solutions like `UI_context_active_but_get_tab_ID()`. So the operator would need to know that it is executed on a tab button that represents a data-block. A single button can now hand operators a data-block to operate on. The operator can request it via the "id" context member (`CTX_data_pointer_get_type(C, "id", &RNA_ID)` in C, `bpy.context.id` in .py). In this commit, it is already set in the following places: * Generic RNA button code sets it to the pointed to data-block, if the button represents a data-block RNA pointer property. (I.e for general data-block search buttons.) * Data-block selectors (`templateID`) set it to the currently active data-block. * The material slot UI-List sets it for each slot to the material it represents. The button context menu code is modified so its operators use the context set for the layout of its parent button (i.e. `layout.context_pointer_set()`). No user visible changes. This new design isn't actually used yet. It will be soon for asset operators. Reviewed as part of https://developer.blender.org/D9717. Reviewed by: Brecht Van Lommel
