Step 6 of 4712 (security review F17). A subscription kept the UserId sent by
the client, and object events (created, modified, deleted, age) were matched by
record type only, so a user could get record names of types it may not read,
delivered to any address. Now a subscription is created for the caller and an
update cannot move it to another user, unless the caller administers users; and
object events skip subscribers without read rights on the record type.
Checked: Service's subscription asked for SuperUser is saved as its own; with
"customer created" subscriptions, Inventory (no read on customers) got 0 events,
Service 1. Full suite: 109 passed, 5 skipped, the same 2 known failures.
