We now have a new whitelist you can put apps in, which
opts them out of the old battery saver mode and new app idle,
but doesn't keep them from going in to doze. This is for a few
special cases that we had previously whitelisted for battery saver,
and inherited to the new modes... ultimately we should figure out
how to get these apps out of the whitelist completely, but this
will help for now.
Apps in this new whitelist are not shown in the UI, because they
are still significantly restricted by not being able to operate
normally in doze. This also means they are still visible in the
list of all apps for the user to be able to put them on/off the
complete whitelist if that is what they really want.
In the course of doing this, I needed to clean up code in the
network policy manager to better separate management of the
two firewall rules that now have different whitelists applied
to them. This also hopefully just generally simplifies and cleans
up that code. Hopefully!

Request benchmarking of devices once per week during normal fstrim

Track individual benchmark and trim results for each volume, and
use scrubbed volume identifier (based on adoptiong age) when logging

Since these alarms allow you to bypass the idle restrictions,
we don't want them to be so open-ended like other alarms. This
implements a policy where the alarm manager will only deliver these
types of alarms every X minutes to each application. For this
initial implementation, X is 1 minute under normal operation and
15 minutes when in idle mode.
To do this, I needed to introduce a new internal allow-while-idle
flag for system alarms, which applications can't get, and doesn't
have these new restrictions.
Also tweaked how the alarm manager handles the alarm window, so it
doesn't change if the alarm gets rescheduld; the window is now always
what as computed based on the time when the alarm was first
given to it.
Finally, fix TimeUtils to be able to correctly print times that
are > 999 days.

Calling println_native with the value of ASSERT will set the abort
message. Unfortunately, there are numerous cases where one thread aborts,
but before that thread can communicate with debuggerd, another thread
calls wtf, which overwrites the abort message from the original
failing thread.
Fix this by changing this to an error level log message.

To follow the correct semantics for when restricts due to
device idle can be applied, power manager need to know about
uid process states like net policy so that it can allow
wake locks from apps that are in the foreground.
Since this is being added to a second place, I reworked things
so that the activity manager now keeps track of per-uid process
states and allows apps to register to listen to those, rather
than having to track lower-level process states and transform
them into an overall uid state. Both net policy and power
manager use this new facility.

Storage devices are no longer hard-coded, and instead bubble up from
whatever Disk and VolumeBase that vold uncovered, turning into
sibling Java objects in MountService. We now treat vold events as
the source-of-truth for state, and synchronize our state by asking
vold to "reset" whenever we reconnect.
We've now moved to a model where all storage devices are mounted in
the root mount namespace (user boundaries protected with GIDs), so
we no longer need app-to-vold path translation. This also means that
zygote only needs to bind mount the user-specific /mnt/user/n/ path
onto /storage/self/ to make legacy paths like /sdcard work. This
grealy simplifies a lot of system code.
Many parts of the platform depend on a primary storage device always
being present, so we hack together a stub StorageVolume when vold
doesn't have a volume ready yet.
StorageVolume isn't really a volume anymore; it's the user-specific
view onto a volume, so MountService now filters and builds them
based on the calling user. StorageVolume is now immutable, making
it easier to reason about.
Environment now builds all of its paths dynamically based on active
volumes. Adds utility methods to turn int types and flags into
user-readable strings for debugging purposes.
Remove UMS sharing support for now, since no current devices support
it; MTP is the recommended solution going forward because it offers
better multi-user support.
Simplify unmount logic, since vold will now gladly trigger EJECTING
broadcast and kill stubborn processes.

Add a simple ArraySet.removeAll(ArraySet) method. This avoids two
allocations, a MapCollections helper and an Iterator object, over
the removeAll(Collection) code.
KeySetManagerService heavily calls removeAll during boot (about 9K
times in AOSP). This reduces GC stress and optimizes the removal
(about half the time the removed collection has only one element).
The removal method in KeySetManagerService is also done under a lock,
so that it gates parallelization efforts in PackageManagerService.

This change modifies how global, secure, and system settings are
managed. In particular, we are moving away from the database to
an in-memory model where the settings are persisted asynchronously
to XML.
This simplifies evolution and improves performance, for example,
changing a setting is down from around 400 ms to 10 ms as we do not
hit the disk. The trade off is that we may lose data if the system
dies before persisting the change.
In practice this is not a problem because 1) this is very rare;
2) apps changing a setting use the setting itself to know if it
changed, so next time the app runs (after a reboot that lost data)
the app will be oblivious that data was lost.
When persisting the settings we delay the write a bit to batch
multiple changes. If a change occurs we reschedule the write
but when a maximal delay occurs after the first non-persisted
change we write to disk no matter what. This prevents a malicious
app poking the settings all the time to prevent them being persisted.
The settings are persisted in separate XML files for each type of
setting per user. Specifically, they are in the user's system
directory and the files are named: settings_type_of_settings.xml.
Data migration is performed after the data base is upgraded to its
last version after which the global, system, and secure tables are
dropped.
The global, secure, and system settings now have the same version
and are upgraded as a whole per user to allow migration of settings
between these them. The upgrade steps should be added to the
SettingsProvider.UpgradeController and not in the DatabaseHelper.
Setting states are mapped to an integer key derived from the user
id and the setting type. Therefore, all setting states are in
a lookup table which makes all opertions very fast.
The code is a complete rewrite aiming for improved clarity and
increased maintainability as opposed to using minor optimizations.
Now setting and getting the changed setting takes around 10 ms. We
can optimize later if needed.
Now the code path through the call API and the one through the
content provider APIs end up being the same which fixes bugs where
some enterprise cases were not implemented in the content provider
code path.
Note that we are keeping the call code path as it is a bit faster
than the provider APIs with about 2 ms for setting and getting
a setting. The front-end settings APIs use the call method.
Further, we are restricting apps writing to the system settings.
If the app is targeting API higher than Lollipop MR1 we do not
let them have their settings in the system ones. Otherwise, we
warn that this will become an error. System apps like GMS core
can change anything like the system or shell or root.
Since old apps can add their settings, this can increase the
system memory footprint with no limit. Therefore, we limit the
amount of settings data an app can write to the system settings
before starting to reject new data.
Another problem with the system settings was that an app with a
permission to write there can put invalid values for the settings.
We now have validators for these settings that ensure only valid
values are accepted.
Since apps can put their settings in the system table, when the
app is uninstalled this data is stale in the sytem table without
ever being used. Now we keep the package that last changed the
setting and when the package is removed all settings it touched
that are not in the ones defined in the APIs are dropped.
Keeping in memory settings means that we cannot handle arbitrary
SQL operations, rather the supported operations are on a single
setting by name and all settings (querying). This should not be
a problem in practice but we have to verify it. For that reason,
we log unsupported SQL operations to the event log to do some
crunching and see what if any cases we should additionally support.
There are also tests for the settings provider in this change.
