                      (other users should also be encrypted, so nothing to do for other users.)

                - Single user entry.
                    - If the target user is encryted, insert to its shadow.
                    - Otherwise insert to its real provider.

                When the (real) calllog provider starts, it copies entries that it missed from
                elsewhere.
                - When user-0's (real) provider starts, it copies from user-0's shadow, and clears

                - When other users (real) providers start, unless it shouldn't have calllog entries,
                     - Copy from the user's shadow, and clears the shadow.
                     - Copy from user-0's entries that are FOR_ALL_USERS = 1.  (and don't clear it.)
