I wasn't able to port some places that rely on isAllowed, getOption, or
related methods.
This adds isRegistered() to UserIdentity, which works like
User::isLoggedIn() but with a better name.
I also cleaned up User mocks in WatchedItemQueryServiceUnitTest in the
course of debugging test failures when switching them to
UserIdentityValue instead of mock Users where possible. They now specify
explicitly which methods are allowed to be called on their User objects,
which I believe is good practice for mocks (and unfortunately PHPUnit
makes it awkward).
Bug: T207972

Storing the user name or IP in every row in large tables like revision
and logging takes up space and makes operations on these tables slower.
This patch begins the process of moving those into one "actor" table
which other tables can reference with a single integer field.
A subsequent patch will remove the old columns.
