These `getAll` methods are not used anywhere within the PDF.js code-base, outside of tests, and were mostly added (speculatively) for third-party users. To still allow access to the same data we instead introduce iterators on these classes, which (slightly) shortens the code and allows us to remove the `objectFromMap` helper function. A summary of the changes in this patch: - Replace the `getAll` methods with iterators in the following classes: `AnnotationStorage`, `Metadata`, and `OptionalContentGroup`. - Change, and also re-name, `AnnotationStorage.prototype.setAll` into a test-only method since it's not used elsewhere. - Remove the `Metadata.prototype.has` method, since it's only used in tests and can be trivially replaced by calling `Metadata.prototype.get` and checking if the returned value is `null`.
