usage while running in background.
The new API is 'int getRestrictBackgroundStatus()' and returns the
following values:
- RESTRICT_BACKGROUND_STATUS_DISABLED: no restrictions
- RESTRICT_BACKGROUND_STATUS_WHITELISTED: restriction but app is
whitelisted
- RESTRICT_BACKGROUND_STATUS_ENABLED: full restriction
The proper way to interprete these values for using metered networks
while running on background is:
- When disabled, there is no restriction and the application could use the
metered networks freely.
- When whitelisted, the application can use the metered network, but should try
to minimize the usage.
- When enabled, the application should not try to use metered networks at
all, since the usage will be denied.

Whether a network is deemed roaming or not was already being tracked
as part of the NetworkIdentitySet, so the underlying data store
already tracks roaming and native data separately. However, this data
was being aggregated together in NetworkStatsCollection#getSummary,
since the NetworkIdentitySet is converted to an iface name for the
purposes of matching, and the iface name will be identical whether or
not the iface is considered roaming. Now it is separated.
Also fixes a long-standing bug in NetworkIdentitySet where an identity
read from a saved file would always be considered roaming == false,
even if it wasn't at the time it was written.

Current usage of NetworkSpecifier: network factory will match a request
if the request has either a (1) empty network specifier, or (2) a
network specifier which is identical to that of the network factory.
Note: 'matching' w.r.t. network specifier - all other matching rules
are still in effect.
Change: add rule (3) or the network specifier of the network factory
is the special string (which is defined as "*" and which user-facing
network requests aren't allowed to use).
Rationale: allows on-demand network creation.
Example:
- Can specify a Wi-Fi NetworkRequest with NetworkSpecifier="ssid"
- It will match a Wi-Fi network factory specifying NetworkSpecifier="*"
- That network factory will bring up a Wi-Fi network, connecting to the
specified SSID.
- Once the network is created it will create a NetworkAgent which will
now have a NetworkSpecifier matching that of the request (not the
match-all special string!)
That final step of making sure that the NetworkAgent matches the request
and not the match-all is critical to delivering any subsequent callbacks
correctly. I.e. your network will only get callbacks which match it.

Currently, we look at network requests that are created by the
current requestNetwork API to see if they look like requests
that could have been created using the legacy
startUsingNetworkFeature API.
This causes those networks to be added to LegacyTypeTracker,
and so cause CONNECTIVITY_ACTION broadcasts, be accessible
using getNetworkInfo(int type), etc. This was done in the L
timeframe so that apps could request networks using the
then-new requestNetwork APIs and still use them using legacy
APIs such as requestRouteToHost.
However, the resulting CONNECTIVITY_ACTION broadcasts are
expensive. requestRouteToHost has been deprecated since L, and
mixing the old and new APIs was never recommended, so it's time
to delete this hack.

The documentation for this method says that the request can be
released using releaseNetworkRequest, but that's not true.
releaseNetworkRequest only takes a PendingIntent, and can only be
used to release a request filed with a PendingIntent.
Fix the docs to say that the request needs to be released using
unregisterNetworkCallback.

This is a partial revert of http://ag/738523 , but not a full
revert because M apps that have gone through the WRITE_SETTINGS
route to obtain permission to change network state should
continue to have permission to do so.
Specifically:
1. Change the protection level of CHANGE_NETWORK_STATE back from
"signature|preinstalled|appop|pre23" to "normal". This allows
apps that declare CHANGE_NETWORK_STATE in their manifest to
acquire it, even if they target the M SDK or above.
2. Change the ConnectivityManager permission checks so that they
first check CHANGE_NETWORK_STATE, and then ask Settings
if the app has the WRITE_SETTINGS runtime permission.
3. Slightly simplify the code in the Settings provider code that
deals specifically with the ability to change network state.
4. Make the ConnectivityService permissions checks use the
ConnectivityManager code to avoid code duplication.
5. Update the ConnectivityManager public Javadoc to list both
CHANGE_NETWORK_STATE and WRITE_SETTINGS.

* commit 'fd18370675f8794807747a18276dd7385e25f06e':
Require the new PACKET_KEEPALIVE_OFFLOAD permission.
Add an error code for generic hardware error.
Fix bugs and crashes in PacketKeepalive API.
Add tests for the PacketKeepalive API.
Add a PACKET_KEEPALIVE_OFFLOAD permission.
Use a CountDownLatch instead of sleep() in NetworkFactory tests.
Get rid of shortSleep() in ConnectivityServiceTest.
Make ConnectivityServiceTest a bit more readable.
This is necessary because currently the wifi code just returns
whatever hardware-specific integer it gets back from the HAL,
which is bad because that will be interpreted by the caller as
one of the error codes defined in this class.
In parallel we'll also modify the wifi code to return this new
error code if the hardware returns an error.

If an app uses the new api (requestNetwork) to bring up MMS, don't
mark it as a legacy request. This was done because the messaging
service had to use a combination of new API and old
(requestRouteToHost) due to api problems. This has been resolved
so don't mark these as legacy requests anymore.
The general stuff is still in for other types due to lack of testing
time but this should be removed altogether in the future.

Merge the CHANGE_NETWORK_STATE permission with WRITE_SETTINGS.
AndroidManifest.xml:
Raised the protection level of CHANGE_NETWORK_STATE permission from
normal to signature|appops and pre23|preinstall for compatibility
provider/Settings:
Wrote new helper methods to check if app is allowed to change network
state.
ConnectivityManager.java & ConnectivityService.java:
Replace enforcement checks for CHANGE_NETWORK_STATE with
checkAndNoteChangeNetworkStateOperations instead.

With this change:
1. NOT_RESTRICTED should be removed from NetworkRequests that bring up
special restricted carrier networks (e.g. IMS, FOTA).
2. NetworkRequests without NOT_RESTRICTED require CONNECTIVITY_INTERNAL
permission to register
3. Binding sockets to networks without NOT_RESTRICTED requires
CONNECTIVITY_INTERNAL permission
