Prevents sending out ConnectivityManager broadcasts when the connection
is repeating the same major state. This means continued wifi scanning
does not generate CM broadcasts (though wifi state broadcasts continue).

Merge commit '83652ebfe1963bcecdcf24383165904223baca6e'
* commit '83652ebfe1963bcecdcf24383165904223baca6e':
Implement API to have new broadcasts replace existing broadcasts.
Use this in various places where it should serve no purpose to deliver
both broadcasts. This is intended to reduce somewhat the flurry of
broadcasts that we churn through during boot.
Accidentally submitted into eclair instead of eclair-mr2.
I apparently rebased my mr2 working dir to eclair by mistake.
Do not merge this so the desired change will survive on mr2 as intended.

Filter out minor Connectivity Notifications.
Don't send a connectivity change notification if the change is in detailed state only.
IE, Disconnect/Idle -> Disconnect/Scanning should not trigger a connection change
notification.

We can now locate event log tag definitions in individual packages
(and java constants for the tag numbers get auto-generated), so move
all the tags used by the system server into the package.
Track requests independently with seperate timers. Clean up on expiration
by just stopping that particular request, not immediately restoring the default.

Mark cellular variants with the same availability, regardless of which are currently in use.
Availability just means the radio is enabled and sees the network, but has no guarantees that
we could connect to an APN if requested.
Fix the requestRouteToHost logic to support apn switches without WIFI.

When switching default networks we should erase any excess dns server entries. The old code
used the wrong index and didn't erase all of them properly.

Fix some race conditions (check isTeardownRequested).

Fix the generation of CONNECTED message to already active subtypes.
Fix the enabling of Data in DataConnectionTracker.

This also refactors ConnectivityService a bit towards supporting multiple simultaneous connections by making each a seem like a seperate Network with it's own stateTracker, etc.
Also adds tracking of process death to clean orphaned startUsingNetworkFeature features.
The previous implementation used a database for storing all of its state, which could cause
a significant amount of IO activity as its tables were updated through the stages of a sync.
This new implementation replaces that in-memory data structures, with hand-written code
for writing them to persistent storage.
There are now 4 files associated with this class, holding various pieces of its state that
should be consistent. These are everything from a main XML file of account information that
must always be retained, to a binary file of per-day statistics that can be thrown away at
any time. Writes of these files as scheduled at various times based on their importance of
the frequency at which they change.
Because the database no longer exists, there needs to be a new explicit interface for
interacting with the sync manager database. This is provided by new APIs on IContentService,
with a hidden method on ContentResolver to retrieve the IContentService so that various
system entities can use it. Other changes in other projects are required to update to the
new API.
The goal here is to have as little an impact on the code and functionality outside of
SyncStorageEngine, though due to the necessary change in API it is still somewhat extensive.
