ProtoInputStream.isNextField() skips over the current field to read the
next tag. This side effect means that calling isNextField prevents the
caller from reading the field it was just on. The "is" prefix makes it
easy to assume that the method has no side effects. Renaming to
nextField(long) with a parameter should help make it clear that the call
is as dangerous as calling nextField().

Similar to how we target DE and CE storage areas, callers need to
specifically ask to work with EXTERNAL storage. This is because
external storage often lives on a separate device from where internal
DE and CE data lives.
As one specific example, if we're moving an app between two
"internal" storage devices, we don't want to clean up the data
for that package on external storage, since it's not being moved.
This change also expands to all mounted external storage devices,
not just the storage backed by the incoming UUID.

'dumpsys usagestats file [user] [interval] [filename]' added.
When all options are specified, this command dumps all usage stats
information stored in the specified filename.
If the filename is not specified, information of all files for the
specified interval is dumped.
If the interval is not specified, information of all files in all of the
intervals for the specified user is dumped.
If the user is not specified, information for all users is dumped.
Also added 'dumpsys usagestats database-info [user]'. This simply
connects the existing dump in UsageStatsDatabase.

A wrong condition causes new sets of daily/weekly/monthly/yearly files
been created before it reaches the rollover time.
Currently database files are pruned by timestamp, it allows 3 years
yearly files, 6 months monthly files, 4 weeks weekly files, 10 days
daily files. Because the bug there could be unlimited number of files
are created as long as files' timestamp falls in these allowed time
spans.
Add a logic to prune files by number of files. Only allow up to 10 yearly
files, 12 monthly files, 50 weekly files, 100 daily files.

Added a new AppUsageLimit group observer which follows the same pattern as
other UsageGroups. This specific observer allows the launcher to query
for the AppUsageLimit, available via the new LauncherApps API below. The
observer can be registered and unregistered via the respective new APIs in
UsageStats.
LauncherApps has a new API which allows it to get the AppUsageLimit for
a specified package and user, initally set via the API in UsageStats.
This new API allows the launcher to query specifics about the limit such
as how much usage time the limit has, and how much total usage time is
remaining.

DEVICE_SHUTDOWN event is used to close all open usage events that do
not have matching closing event when device is shut down. For example,
ACTIVITY_RESUMED or FOREGROUND_SERVICE_START are open events, the
DEVICE_SHUTDOWN event will close the usage session of the open events.
At orderly shutdown like selecting Power Off or Restart after pressing
power button, a DEVICE_SHUTDOWN event is sent to UsageStats.
UsageStats persists UsageStatsDatabase to disk immediately.
When power button is pressed for 3.5 seconds (configured by
config_veryLongPressTimeout in config.xml). A DEVICE_SHUTDOWN
event is sent to UsageStats. UsageStats persists UsageStatsDatabase
to disk immediately.
This is the mechanism that we do not lose UsageStats data when the
device is shut down.
When the device boots up, if the last event is not
DEVICE_SHUTDOWN, we add a DEVICE_SHUTDOWN with timestamp set to be the last
time database file is persisted. This is to handle the case device
shutdown abruptly due to power drained or cold temperature.

ACTIVITY_RESUMED is synonym to existing MOVE_TO_FOREGROUND.
ACTIVITY_PAUSED is synonym to existing MOVE_TO_BACKGROUND.
ACTIVITY_STOPPED when an activity becomes invisible on the UI.
2. In UsageStats.java, add API getLastTimeVisible() to report last time the
app is visible (ACTIVITY_RESUMED or ACTIVITY_PAUSED), add API getTotalTimeVisible()
to report total time the app is visible.
The existing API getLastTimeUsed() can report last time the app is in
foreground (AKA have focus).
The existing API getTotalTimeInForeground() can report total time the
app is in foreground (AKA have focus).
3. UsageStats.getTotalTimeVisible() can report screen usage for
split-screen mode and picture-in-picture mode.
4. Because in the same package, activity can be instantiated multiple times,
In UsageEvents.Event class, add a member mInstaceId for activity's
instance ID, add interface getInstanceId() to retrieve the instance ID.
