Now pure DA (not PO, not DO) aren't allowed to change the password
if one is already set.
Also update "isDeviceOwner" check and make sure we always take
user-id into account. If one really wishes to check the package name
only, then use getgetDeviceOwner() instead.
Also change the enforceNotManagedProfile() check to what's more
generic in the FBE world.

This information, if set, will be shown in the lock screen instead
of the user owner information and the settings tile will be made readonly
(implementation in following CLs).

This will allow AMS to call into DPMS within the AMS lock instead,
which will help I1537bd57b34696768ee81a979d53bb396efbc12a.
- AM.clearApplicationUserData() will not be allowed for any DA
apps.

... DISALLOW_ADJUST_VOLUME, instead of UserManager pushing
new settings to AudioService.
Also:
- Allow PO to set these two restrictions.
- Now AS.setMasterMuteInternal() respects mUseFixedVolume to make
it consistent with readPersistedSettings().
- When a user switches and restores the mute state in
AS.readPersistedSettings(), also check the current user restrictions
in addition to system settings. Because of the delay in AudioService
before persisting the mute settings in setMasterMuteInternal() and
setMicrophoneMute(), there's was an edge case
DISALLOW_UNMUTE_MICROPHONE and DISALLOW_ADJUST_VOLUME would be ignored
when the user switches right after they are set.

The DPC can use it to tell if provisioning a managed profile or for
device owner would work or not.

Added mUsersLock - short-term lock for internal state, when interaction and
synchronization with PM is not required. Modifications to mUsers and
mRemovingUserIds must be guarded by 3 locks: mInstallLock, mPackagesLock and
mUsersLock. While reads can use mUsersLock.
Testing revealed that the following methods in UMS often cause contention:
- exists
- getUserInfo
- getProfileParent
They all now use a short-term lock mUsersLock for reads.

- Now even if a user restriction is set via UserManager, it'll be correctly
enforced.
- Changed the way AudioService enforces the OP_MUTE_MICROPHONE and
OP_AUDIO_MASTER_VOLUME app ops -- previously, when they're set, even a muting
call would be rejected. This was why DPMS.setUserRestriction() used different
calling orders for DISALLOW_UNMUTE_MICROPHONE/DISALLOW_ADJUST_VOLUME depending
on setting them or clearing them.
Now, even when the app ops are set, we still allow muting calls.

- Now DPMS remembers user restrictions set by DO / PO in their ActiveAdmin.
- User restrictions set by DO/PO will no longer be saved by UserManger. Instead,
when needed, UMS will consult DPMS to build "effective" user restrictions.
- UM.getUserRestrictions() will now always return "effective" user restrictions.
- DPMS migrates existing user restrictions per the eng spec.
- Also now UM.setUserRestrictions() will crash. UMS.setUserRestrictions() has
been removed.
This was needed because UM.setUserRestrctions(UM.getUserRestrictions()) will no
longer be a valid use like it used to be.
- Also introduced a fined-grained lock for user restrictions in UM to avoid
deadlock between DPMS and also for better performance.

When File Based Encryption is present, allow the verify/write of
passphrases to be per-user (it used to always bubble up to the parent
user assuming it is a per-device passphrase).
This is part of the work for the Separate Work Challenge.

- Start persisting restrictions set by DO/PO.
- Also dump user restrictions on dumpsys
- More changes will follow, including migration.
- Now System settings are mockable.

It was because UserManager.get() returns a static cached instance but
we should always be using the mock instance that's created for each test.

- Extracting into a factory allows us to use mocks in other classes.
(Such as Owners.)
- Also removed broken test ApplicationRestrictionsTest. Instead added a new
simplified test to DevicePolicyManagerTest.
- Also stop caching rarely used instances in DPMS.

Change-Id: Ice9e57204b18e7b5f6b115126dab2209041439c2
- Now all services that DPMS uses are injectable.
- Introduce some wrappers to make static methods and final class mockable.
(e.g. for Binder.getCallingUid())
- In unit tests we replace those with Mockito mocks, except we use a partial
mock for PackageManager, because we use way too many methods of this and
most of them are okay to use directly.
- To install a partial mock to PackageManager, I needed to make
ApplicationPackageManager @hide public non-final.
- For a starter, added tests for DPM.setAmin().

- setDeviceOwner() now takes a user ID. (We can infer it from Binder, but
we still need it for the dpm command.)
- Change broadcast target UID for DO to the DO user
- Start the DO user on boot complete.
TODO Investigate whether this is actually the good timing.
TODO Prevent the DO user from being killed
