T90907: Change "Link materials to the object or the object's data" on multiple objects

Commits

rB6845aad1a271: Fix T90907: RNA pointers for material slots are not unique across IDs

Summary

Caused by rB1a81d268a19f: Materials: support changing materials during evaluation.

This caused e.g. ALT-clicking the 'Link' button to not propagate to
other selected objects (same as the 'Copy To Selected' context menu
entry).

If these are not unique across IDs, checks in ui_selectcontext_begin()
or copy_to_selected_button() could fail.

Now offset by ID pointer.

thx @Jacques Lucke (JacquesLucke) for clarification on the POINTER_* macros (and why
not to use them)!

dont use POINTER_AS_INT on 64bit pointer

I think this could should just not use the POINTER_* macros at all. Those are meant to be used when converting indices to pointers and back.

1330	This is still using `POINTER_AS_INT` on a pointer. This works by accident.
