One conflict, in redact lib.rs: the module list, where main added `elsewhere` and
`identification` (#6714) and this branch `globals`. All three stay, in order.
Main's #2448 work also added a sixth step to `apply`, after the verification and the pattern
guard: `metadata::scrub` removes the `/Info` entries and the catalog's and pages' XMP that repeat
the removed text. An image that only such a packet refers to leaves the file then, after
`unshare` had looked for what left, so its shared dictionary stayed. `unshare` now runs after
the scrub, last of what can take something out. Storing images again changes no page's content
and no pattern cell, so the verification and the pattern guard before it check the same pages
they did. The crate's doc says the dictionary goes last. Remove Hidden Information's order is
unchanged: main's changes to `sanitize.rs` only read (`owned_values`).
Test: `an_image_only_the_scrubbed_metadata_refers_to_takes_a_shared_jbig2_dictionary_too`. An
image under the mark is also named by the catalog's XMP, which repeats the text removed beside
it. After the redaction the packet is gone, the image on the other page is stored again, and
the dictionary is gone too.
