wouldn't make much sense. Also with this change, we can move
StatusValue to MediaWiki\Status as well.

Add services and utilities for automatic creation of temporary user
accounts on page save, in order to avoid exposing the user's IP
address.
* Add $wgAutoCreateTempUser, for configuring the system
* Add TempUserConfig service, which interprets the config.
* Add TempUserCreator service, which creates users during page save as
requested by EditPage. With proxy methods to TempUserConfig for
convenience.
* Add table user_autocreate_serial. Table creation is necessary before
the feature is enabled but is not necessary before deployment of this
commit.
