We used the system proterties as a shared memory mechanism
to propagate information to local settings caches when the
content has changed and the cache should be cleared. The
system properties are unfortunately updated asynchronously
leading to cases where clients may read stale data.
This change adds a simple int array data structure backed
by shared memory which guarantees individual values are
atomically read and updated without memory tear. Multi-
index opearations are not synchronized between each other.
The settings provider is using the new data structure to
propagate the settings generation which drives when caches
are purged.
We have a single memory array keeping the generation for
different settings tables per user. Since memory array is
not a compact data structure and the user space exceeds
the memory array size we use an in-memory map from keys
to indices in the memory array where the generation id of
a key is stored. A key is derived by the setting type in
the 4 most significant bits and the user id in the 28 least
significant bits.
The mapping from a key to an index is cleared if the user is
removed and the corresponding index in the memory arry is
reset to make it available for other users. The size of the
memory array is derived from the max user count that can be
created at the same time.

To support moving DownloadManager, add new JobScheduler network type
constraint that matches "any network except roaming." Also add an
API to get a specific JobInfo by ID.
Since the default network can be different on a per-app basis, and
individual apps may be blocked due to app standby, evaluate job
connectivity constraints on a per-UID basis. To implement this
cleanly, add NetworkInfo.isMetered() to match the isRoaming() API.
Add new DownloadManager APIs to support charging and device idle
constraints, which are plumbed through to JobScheduler under the
hood when scheduled.
Add filtering to JobScheduler dumpsys to omit noisy details for
packages the caller isn't interested in.

The PackageInstaller app manages side-loading apps as well
as permission management. It should be updatable, hence
should rely on system APIs to talk to the platform. This
is the first step of defining an API boundary.

- New service TVRemoteService triggered by SystemServer
- Provider service proxy and watcher for maintaining connections to unbundled
services which have the BIND_TV_REMOTE_SERVICE permission.
- Shared library to facilitate connections between unbundled service and
TVRemoteService.
- Unbundled service needs TV_VIRTUAL_REMOTE_CONTROLLER
permission to be fully functional.

* introduced a new intent DISMISS_KEYBOARD_SHORTCUTS and
and new public API in Activity (which sends a broadcast
to KeyboardShortcutsReceiver) which applications can
use to dismiss the keyboard shortcuts.
* plumbing and implementation for a new call to dismiss
keyboard shortcuts from PhoneWindowManager and used it:
** when starting activities invoked via Search+key
** when starting activities invoked via META
** when starting activities via application launch keys
* removed unused variable in
Activity#onProvideKeyboardShortcuts
Note that for apps started via touch (aka non-shortcut)
like tapping the Settings gear icon from the notification
bar the menu is not automatically dismissed.

Currently it does not use a ClassLoader to read
any super state, which can cause crashes for
custom views using the class but on a different
class loader.

This patches changes how captive portal tests and network lifecycle
events are logged as connectivity events:
- it splits NetworkMonitorEvent into two event classes:
- ValidationProbeEvent for logging individual probe events.
- NetworkEvent for logging network connection, validation,
lingering, and disconnection.
- it removes the redundant CaptivePortalCheckResultEvent class.
The information logged in CaptivePortalCheckResultEvent was already
logged by NetworkMonitorEvent, but missing the evaluation durations.
It is now logged by ValidationProbeEvent.
- it removes the CaptivePortalStateChangeEvent class, which is now
redundant with NetworkEvent, but missing evaluation durations.
In addition, it adds event logging when ConnectivityService puts a
network into lingering or removes a network from lingering.

- fold IpReachabilityMonitor* classes into a single IpReachabilityEvent.
- only log an event for NUD_FAILED Netlink answers.
- distinguish between NUD_FAILED with or without lost of provisioning.
- do not record host ip addresses.
- record interface name instead of interface index when losing
provisioning.
- also return an error code when probeNeighbor fails, and log this error
code in IpReachability events.
