A new defined method of uuidToBytes is used to convert
Bluetooth uuid to bytes in the case of BLE advertising.
But the most significant 16 bits of a 32-bit uuid
will be cleared after the and operations with
0X0000FFFF00000000L in the function of
getServiceIdentifierFromParcelUuid.
0XFFFFFFFF00000000L should be used as bit mask.

This patch defines a new WakeupStats event in ipconnectivity.proto and
populates these events from the NFLOG wakeup events stored in
NetdEventListenerService.
There is one WakeupStats object per known interface on which ingress
packets arrive and may wake the system up.
Example from $ adb shell dumpsys connmetrics list:
UPDATEME
...
WakeupStats(wlan0, total: 58, root: 0, system: 3, apps: 38, non-apps: 0, unrouted: 17, 6111s)

Before this change, ZygoteProcess.preloadPackageForAbi returned
as soon as the command was written to the zygote socket and not
after the preload completed. This meant that there was a small
window of time before the server side of the socket polled its FDs
where a second command could be written to the zygote socket. This
would lead to only one of the commands being processed and the
other being dropped. The client side of that socket would then wait
forever for a response and bring down the system once the watchdog
timeout was hit.
Example failure case :
--------------
system_server：send command(preloadPackage)
system_server：send command(fork)
zygote：poll & process command(preloadPackage) // the fork command is dropped.
Example of normal operation :
------------------
system_server：send command(preloadPackage)
zygote：poll & process command(preloadPackage)
system_server：send command(fork)
zygote：poll & process command(fork)
This change makes preloadPackageForAbi synchronous, which ensures
that each POLLIN event corresponds to precisely one command.

This patch stores NFLOG packet wakeup events sent by Netd to the system
server into a ring buffer inside NetdEventListenerService. The content
of this buffer is accessible by $ dumpsys connmetrics or $ dumpsys
connmetrics list, and is added to bug reports.
The wakeup event buffer stores currently uid and timestamps.

(cherry picked from commit c57a01c166)
Always-on VPN is a feature introduced in N. Since then, all VPN apps
targeting N+ are assumed to support the feature, and the user or the DPC
can turn on / off always-on for any such VPN app. However, a few VPN
apps are not designed to support the always-on feature. Enabling
always-on for these apps will result in undefined behavior and confusing
"Always-on VPN disconnected" notification.
This feature provides a new manifest meta-data field through which a VPN
app can opt out of the always-on feature explicitly. This will stop the
always-on feature from being enabled for the app, both by the user and
by the DPC, and will clear its existing always-on state.
A @hide API is provided to check whether an app supports always-on VPN.
Documentation is updated to reflect the behavior change.

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

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.
