When Wi-fi connects at L2 layer, the beacons reach and the device
can maintain a connection to the access point, but the application
connectivity can be flaky (due to bigger packet size exchange).
We now use Watchdog to monitor the quality of the last hop on
Wi-Fi using signal strength and ARP connectivity as indicators
to decide if the link is good enough to switch to Wi-Fi as the uplink.
ARP pings are useful for link validation but can still get through
when the application traffic fails to go through and thus not best indicator
real packet loss since they are tiny packets (28 bytes) and have
much low chance of packet corruption than the regular data
packets.
Signal strength and ARP used together ends up working well in tests.
The goal is to switch to Wi-Fi after validating ARP transfer
and RSSI and then switching out of Wi-Fi when we hit a low
signal strength threshold and waiting until the signal strength
improves and validating ARP transfer.

Except it does nothing.
But eat resources.
Yum, yum!
Current we create five processes. The main process sucks up 16MB of
RAM and creates a full-screen window; only on high-end devices does
the window (and process) use the GPU.
The second through fourth processes just sits there not really doing
anything except using process overhead.
The fifth process runs a background service, slowing eating RAM until
it gets killed by the system (as the system will ultimately do with
background services). It also creates a full-screen window, and always
uses the GPU even on low-end devices.

Found cleaner way to improve recents scrolling
performance on crespo-- instead of rendering the
background in the items, instead we just set
a window flag. Removed need for a lot of code.
This change introduces a few new bits of data on
Notification that will help the Notification Manager and
System UI route and display them more intelligently:
-> priority: an integer in a predefined range that
indicates the app's best guess as to the relative
importance (to the user, right now) of that information
-> kind: a tag (really, set of tags) indicating the general
type of notification (realtime, asynchronous, etc)
-> extras: a Bundle of additional key/value pairs
associated with this notification (currently @hidden)
The notification manager takes these data into account when
assigning to each notification a score which is passed with
the notification on to the system UI, where it can be used to
affect presentation. For example:
- Spammy apps (identified explicitly by the user or by
some other means) will have their notifications scored
very negatively by the notification manager, allowing
the UI to suppress them
- Notifications of higher score might be shown larger
or in a different way
- Very important notifications (indicated by a very high
score) might interrupt the user during an otherwise
important task (videochat, game, etc)
Implementation note: This replaces/extends the old internal
notion of "priority", which was mostly used to organize
ongoings and system notifications at the top of the panel.

Improving load time by:
- using window animation for fade-in and not
waiting to create HW layer
- starting loading of thumbnails/icons earlier
- only initially creating views for the first
screenful of items
- recycling views

Introduce second snooze timestamp to support dismissal of data usage
warning notification. Also explicitly set notification "when" to

Fixing CV failure. In some scenario where ERI table expects
"Roaming Indicator OFF", R icon was still displayed on
the status bar. This patch is to update the logic so that
only ERI table is used to display R icon in case of CDMA.

Because the NetworkInfo included in CONNECTIVITY_ACTION broadcast
extra does not reflect the state applicable to the calling UID, and
the last sticky broadcast may have stale state, transition to calling
ConnectivityManager.getActiveNetworkInfo() directly.

Carrier name is blanked if out of service and connected to

"No internet connection" is shown if out of service without
