"setup complete").

The BMS constructor is now only responsible for setting up the system
service. User registration logic is moved to its own helper that
Trampoline calls during a user unlock callback.
** Logic **
All IBackupManager methods that BMS implements now use bookkeeping to
get the UserBMS instance to act on. Currently the system user instance
is hardcoded in most methods as we don't pass in the user id parameter
(except for a few added in ag/5667585).
If these methods are called on a non-registered user, we log and return
a default value.
** Tests **
Each IBackupManager method now has four corresponding tests:
1) Permission denial test: No INTERACT_ACROSS_USERS_FULL permission +
non-calling user id = security exception (added in ag/5667585, only for
methods that take in an user id param currently).
2) Permission grant test: INTERACT_ACROSS_USERS_FULL permission +
non-calling user id = call forwarded.
3) Registered user test: Passing an user id that has a corresponding
UserBMS instance -> delegate call to that UserBMS instance.
4) Unknown user test: Passing an user id that has no corresponding
UserBMS instance -> no call forwarded.
These tests will be updated when more methods take in an user id param.

Move per-user state initialization (directories for bookkeeping data and
transport manager) from BMS to UserBMS.
The UserBMS constructor is now private and callers should use the static
helper to create a new instance. This is primarily for three reasons:
1) Allows for extracting logic out of the constructor into helpers.
2) Allows for performing necessary user-specific setup in the future
such as data migration.
3) Allows for writing unit tests without having setters/getters
exclusively for tests.

The backup enabled setting BACKUP_ENABLED was deprecated since Android
N and replaced by a file containing enabled state.
Stop migrating this setting for the system user to be able to
consolidate starting the backup service for system and non-system users.
There's been several Android versions since the deprecation that the
chance we need the setting is slim (as devices shouldn't OTA from N to
current). Without the setting, the default would be backup off (absence
of file) which can then be enabled again via SUW or Settings.

BMS is split into GlobalBMS and UserBMS.
UserBMS:
- Core backup/restore implementations and bookkeeping.
- Will be per user in a future CL (only one instance in this CL to limit
scope of changes).
GlobalBMS:
- System service definition, interaction with Trampoline, user-aware
operations.
- Will be renamed back to BMS in a future CL (so BMS history can follow
UserBMS in this CL).
*** Reviewers, please pay attention to the patchset breakdown to better
understand what is a rename/move vs. new changes ***
* Base -> Patchset 2: BMS splits into GlobalBMS and UserBMS (MOVE ONLY)

- Switch references from BMS to GlobalBMS in Trampoline.java.
- Change the definition of the system service in SystemServer.java to
GlobalBMS.
- Instantiate one instance of UserBMS in GlobalBMS constructor.
- Add all IBackupManager methods, which for now just directly calls the
corresponding method in UserBMS.
* Patchset 3 -> Patchset 4: Migrate usages of BMS in code (RENAME ONLY)
Find and replace, no new functionality.
* Patchset 4 -> Patchset 5: Migrate usages of BMS in tests (RENAME ONLY)

Now that checkstyle runs a preupload hook for frameworks/services, when
we move BMS -> UserBMS, checkstyle will complain of errors because it
sees it as a new file.
This CL just fixes checkstyle complaints (mostly adding javadocs,

UserBMS can have as little changes as possible to ease review.

Part of prep to make BMS multi-user aware.
Current disable logic:
- Trampoline is a proxy to BMS that enforces system- and policy-imposed
disabling of the backup service (user-configurable disabling is in BMS).
- Backup service can be disabled by system property = permanent disable.
- Backup service can be disabled by a privileged caller like Device
Policy Manager = temporary disable.
In multi-user context:
- The system user is the main actor in creation and disabling of the
backup service.
- BMS is only created when the system user is unlocked -> system user
will always be unlocked first and is always running.
- Device Policy Manager acts on the system user and shuts down backup
mechanism for the whole device -> disable for system user disables for
all users.
- Non-system users have no impact on the creation/disabling of the
backup service.
This CL:
- Clean up and document the above logic.
- Move synchronization on backup suppress file from 'this' to private
lock.
