This introduces PageUpdater to replace WikiPage::doEditContent,
and DerivedPageDataUpdater, to replace WikiPage::doEditUpdates
and WikiPage::prepareContentForEdit.
See docs/pageupdater.txt for a description of their
functionality.
MCR migration notes:
* The interface of PageUpdater is expected to
remain mostly stable after this patch. Code that has been using
WikiPage::doEditContent can be confidently migrated to using the
new mechanism for revision creation.
* This patch keeps the code inside PageUpdater largely aligned
with the old code in WikiPage, to make review easier to to avoid
mistakes. It is intended to be refactored further, moving
application logic into stateless services.
* DerivedPageDataUpdate is intended as a stepping stone for further
refactoring. Its behavior is designed to be compatible with
callback code that currently relies on
WikiPage::prepareContentForEdit. Much of the code that currently
lives in DerivedPageDataUpdate should be factored out into
services, all behavior relevant to calling code should be exposed
via narrow interfaces.

The RevisionSlotsUpdate interface represents a change to a pages slots,
as applied by an edit.
This also introduces RevisionSlots::hasSameContent and pulls up
getTouchedSlots() and getInheritedSlots() from MutableRevisionStore
to RevisionStore, in preparation of using these classes in the
refactoring of WikiPage::doEditContent and friends.
