Add idle mode support to the alarm manager. Introduce
a new concept of flags associated with alarms to tell
the alarm manager how to treat the alarm -- they allow
everything from the alarm that will bring us out of idle
mode, to alarms that are allowed when idle or should
also bring us out of idle. The standalone boolean is
now also a flag.
(Note there is currently no protection from user space
setting the flags however it wants; I will be working
on that in a follow-up change.)
When in idle mode, the alarm manager pushes all alarms
that shouldn't execute during that time over to a
separate list that is not executed until out of idle.
To help with this, I reworked a bit how Alarm objects
are managed, so that when rebatching or moving between
lists we don't have to allocated new objects but can
just use the same existing instance.
Also tweaked the sync manager to deal with idle mode,
which currently just means doing the same thing as when
low on storage -- turning off sync.
Add new ACTION_CHARGING and ACTION_DISCHARGING broadcasts
that apps can listen for to know when the device is actively
charging and discharging. These are better than the old
POWER_CONNECTED and POWER_DISCONNECTED ones because we only
report charging when we actually see that there is enough
power being provided to charge the battery (and will report
discharging if there is not enough power).
The job controller uses these new actions for scheduling
jobs that want to run while plugged in. Removed the
"stable charging" stuff while doing so, since the new
charging state serves as an even better signal for that.
Introduced two new process states: FOREGROUND_SERVICE and
TOP_SLEEPING. This will allow us to treat foreground services
specially (such as still allowing network access to them for
background music playback) while not mixing them together with
whatever happens to be the top activity while the device is
asleep.
Also some other small cleanup here and there.

PackageManager now offers to load/unload packages when expanded
volumes are mounted/unmounted. Expanded storage volumes are still
treated as FLAG_EXTERNAL_STORAGE from a public API point-of-view,
but this change starts treating the INSTALL_EXTERNAL flag as
exclusively meaning ASEC containers.
Start tracking the UUID of the volume where a package is installed,
giving us a quick way to find relevant packages. When resolving an
install location, look across all expanded volumes and pick the one
with the largest free space. When upgrading an existing package,
continue preferring the existing volume. PackageInstaller now knows
how to stage on these volumes.
Add new movePackage() variant that accepts a target volume UUID
as destination, it will eventually move data too. Expose this
move command through "pm" command for testing.
Automount expanded volumes when they appear.

Add StorageManager methods that work with Disk and Volume IDs instead
of paths which can change over time. For example, a freshly formatted
volume has a different UUID and mount point, even though it's the same
volume.
Update StorageEventListener to be all one-way calls to avoid blocking
while dispatching events. Add new listener method for Volume-level
state changes. The existing state method will remain focused on the
per-user state reflected by StorageVolume. Switch listeners over to
using the more robust RemoteCallbackList pattern under the hood.
Change external ASEC scanning logic in PackageManagerService to be
driven by listener events, instead of explicit MountService calls.

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.

In order to not deadlock the system, we need to retrieve
WiFi energy info outside of the BatteryStats lock. We do this,
then pass that data down to BatteryStatsImpl to process.

Instead of just tracking the total number of wakeup alarms
per package, track a count for each tag. Note this is only
wakeup alarms, not non-wakeup alarms.
Also tighten up the code a bit by exposing the actual ArrayMap
container through most of the BatteryStats API, so we can more
efficiently iterate over them (which is all we ever want to do
with those containers at that point).
Finally remove all printing of "since unplugged" stats, as
another step towards completely removing that tracking. If
nobody screams, hopefully soon we can go through and just get
rid of all the extra state we are carrying around that is
tracking that data.
Also note that currently the per-tag wakeup alarm data is
being reported in the human-readable stats, but in the checkin
data it is still being rolled up into a single number. To fix
this, I need to completely rework the pkg entry line to have
separate data for services and wakeup alarms (so have three
types -- pkg for the start of a package, wal for a wakeup
alarm, svc for a service).

- There is now an API for people to find out about
its state.
- Moved DeviceIdleController to be closer to the
power manager implementation, since they are
closely related.
- Job scheduler now knows about idle state and doesn't
run jobs while the device is idle.
- Battery stats now keeps track of "idling" vs "idle mode".
Idling is when we consider the device to be idle,
independent of whether we are actually in deep idle mode.
This allows us to keep track of longer-term changes
independently of cycling in and out of idle mode.
- Battery stats also now keeps track of package changes in
its daily stats.
- Small optimization to network policy manager service to
not touch uids that do not have the NETWORK permission.

Introduce a new device idle controller service that
monitor's the device state and determines when to go
in to idle mode. When in idle mode, all we do right
now is turn off network access the same as we do for
power save mode. Many more things should come in the
future -- stopping the alarm manager from scheduling
(most) alarms, telling GmsCore for it to stop doing
stuff, etc.
Battery stats now has state tracking for devie idle
mode, as well as events for the reasons we can come
out of idle mode (significant motion or the device
becoming active). Also added new events noting when
packages are installed.
Renamed the "low power" event in battery stats to
"power save" because the former was just way too
confusing.
Finally, fix buffer size reading kernel wake locks.
(Stupidly, just increasing the buffer size. Ideally
we should try to be smarter and grow our buffer to
fit the data available, but I'll leave that for
another time.)

Also add API for voice interaction service to control
whether the system should hold a wake lock while it is
working with an activity (and actually *do* hold a wake
lock while doing so, duh!).
And while in there, clean up the launching wake lock to
correctly give blame to the app that is launching.

If we close the PFD status channel before returning, then the Looper
will take care of unregistering it correctly but it will end up
doing extra work to rebuild the epoll set to work around a limitation
of the epoll interface. If we unregister the FD first then this
extra work will not be required so it's slightly more efficient
this way.

Optimize parceling of AssistData (which is now renamed to
AssistStructure) by pooling duplicated class name strings.
Change text associated with a view node to a CharSequence,
so styling information comes along.
Include global text attributes -- size, colors, etc.
Introduce a new AssistContent structure, which allows us
to propagate information about the intent and data the
activity is looking at. This further allows us to propagate
permission grants, so the assistant can dig in to that data.
The default implementation propagates the base intent of an
activity, so if for example you bring up the assistant while
doing a share the assistant itself has the same information
and access that was given to the share activity (so it could
for example share it in another way if it wanted to).
Did some optimization of loading PersistableBundle from xml,
to avoid duplicating hash maps and such.
Changed how we dispatch ACTION_ASSIST to no longer include
the more detailed AssistStructure (and new AssistContent)
data when launching; now the example code that intercepts
that needs to be sure to ask for assist data when it starts
its session. This is more like it will finally be, and allows
us to get to the UI more quickly.
