The usage of the lib pointer was cryptic to say the least, it was essentialy used to allow or not local IDs results in the mapping old_id_pointer -> new_id_pointer lookup result. Now: - Explicitely pass a boolean to allow or not local ID as result in lower-level code. - Pass the 'self ID' pointer instead of its library to the whole liblinking code (that was already the case in a few places). Note that naming of the 'self id' pointer is currently very inconsistent throughout the readfile liblink code, this will have to be cleaned up in a separate step later. For now, `self_id` has been chosen for new code as it matches the terminology in lib_query code. The later change can also allow finer handling of lookup on undo, based on how it was re-read (or not), should the need for this arise.
