A handle for managing updates for derived page data on edit, import, purge, etc.
DerivedPageDataUpdater instances are designed to be cached inside a WikiPage instance, and re-used by callback code over the course of an update operation. It's a stepping stone on the way to a more complete refactoring of WikiPage.
When using a DerivedPageDataUpdater, the following life cycle must be observed: grabCurrentRevision (optional), prepareContent (optional), prepareUpdate (required for doUpdates). getCanonicalParserOutput, getSlots, and getSecondaryDataUpdates require prepareContent or prepareUpdate to have been called first, to initialize the DerivedPageDataUpdater.
MCR migration note: this replaces the relevant methods in WikiPage, and covers the use cases of PreparedEdit.

| MediaWiki\Storage\DerivedPageDataUpdater::prepareContent | ( | UserIdentity | $user, |
| RevisionSlotsUpdate | $slotsUpdate, | ||
| $useStash = true ) |
Prepare updates based on an update which has not yet been saved.
This may be used to create derived data that is needed when creating a new revision; particularly, this makes available the slots of the new revision via the getSlots() method, after applying PST and slot inheritance.
The derived data prepared for revision creation may then later be re-used by doUpdates(), without the need to re-calculate.
