This patch ensures that subtract() between two NetworkStats object will
return a delta with no negative entries in all cases.
When the stats delta contains some negative values, there are clamped to
0. Some logging is added when this happens.
This is what's expected by NetworkStatsHistory#recordData().

For some networks such as mobile data connections, its LinkProperties
does not contain routes for the local subnet so no such route is added
to the interface's routing table. This can be problematic especially
if the device is in VPN lockdown mode where there exists high-priority
PROHIBIT routing rule which in turn blocks the network's default gateway
route from being added (next hop address hitting the prohibit rule).
We fix this by patching LinkProperties to always include direct connected routes
when they are received by ConnectivityService. This has the added advantage that
when apps get LinkProperties, they see the directly connected routes as well.

* Binder object may become null between null check and actual invocation
if using a instance private variable assignable by service connection
callbacks
* The solution to this problem without locking is to assign existing
binder variable to a local final variable before the null check
* Any further invocation to a disconnected binder object will result in
RemoteException that is caught by the try-catch block
* Read and write to volatile variable is always atomic and hence thread-safe
* Removed unnecessary synchronization in BluetoothAdapter constructor
* Private mConnection objects should be final
* Simplfied several return statements where booleans can be returned
directly
* Removed unnecessary catches for NPE since there won't be any

- "&&", "+", "||" should not be at the end of line
- Non-static private variable should be like "mVar"
- Private static variable should be like "sVar"
- Code file should always end with newline
- Inherited methods should be annotated with @Override
and no @hide tags
- Public methods should always have a JavaDoc entry

Currently, we only count add tethering traffic to per-UID
stats, but not to total data usage (i.e., dev and XT stats). This
is correct for software tethering, because all software forwarded
packets are already included in interface counters, but it is
incorrect for hardware offload, because such packets do not
increment interface counters.
To fix this:
1. Add an argument to ITetheringStatsProvider#getTetherStats to
indicate whether per-UID stats are requested. For clarity,
define integer constants STATS_PER_IFACE and STATS_PER_UID
to represent these operations.
2. Make NetdTetheringStatsProvider return stats only if per-UID
stats are requested. (Otherwise tethering traffic would be
double-counted).
3. Make OffloadController's stats provider return the same
stats regardless of whether per-UID stats were requested or
not.
4. Make NetworkStatsService add non-per-UID tethering stats to
the dev and XT snapshots. The per-UID snapshots were already
correctly adding in per-UID stats.

Calls to old advertising API (startAdvertising), should never throw
exceptions. Instead, it used to post failure callback. This behaviour
was accidentally modified when implementing new API. Right now, instead
of posting error callback, we throw IllegalArgumentException if we fail
to obtain BluetoothGatt object, or the call to startAdvertisingSet
fails.
This patch brings back the old behaviour to the API. It also makes new
API post callback instead of throwing exception in this error case.

Also moving relevant test files into tests/net as part of runtest
framworks-net.
Also removes testHashCode in LinkAddress() because this test relies on
the assumption that hashCode() is stable across releases or jdk
versions, which is absolutely not true.
This creates maintenance work for little benefit since hashCode is
already tested as part of the equality test.
For instance this test is now broken because hashing for InetAddress
changed.

This patch loosens the validation checks when a NetworkAgent updates it
NetworkCapabilities: instead of checking that capabilities labeled as
"immutable" stay identical across updates, it is now accepted to change
immutable capabilities in a way that the new NetworkCapabilities
satisfies the old NetworkCapabilities.
This allows a NetworkAgent to update itself in order to match more
requests, but will still catch NetworkAgents that sends degradation
updates causing potentially requests to not match anymore.

This patch moves *.aidl files from
frameworks/base/core/java/android/bluetooth into system/bt/binder. This
is in preparation to convert the Bluetooth deamon into native
implementation piece by piece.
In order to do that, one must have C++ header files, and paths to them
with AIDL files, and */java/* folder didn't seem as proper place for
that. Additionally, keeping AIDL files out of framework/base will not
require creating dependency on this huge project, which should help
keeping the compilation fast.

(cherry picked from commit 06ae9c665b)
This is a refactoring with no behavior change.
The new class provides an abstraction layer to hide knowledge
about OkHttp-specific APIs. Logic from android.net.Network that
knew about OkHttp is moving into that abstraction layer.
This CL refactors android.net.Network to make use of this
abstraction layer instead of the tight coupling onto OkHttp
APIs. The class no longer imports any classes from okhttp
packages.
The values of mDns and mConnectionPool, which never change after
the initial call to maybeInitHttpClient(), are now set directly on
the AndroidHttpClient instance when it is constructed in that method.
Applications can overwrite getSocketFactory() and might depend on
that method being called (and the result used) every time a
connection is opened; therefore, for maximum app compatibility this
call was kept inside openConnection().
This CL is a prerequisite for introducing an additional frameworks
dependency on a richer API than HttpURLConnection.
