This change sets LOCAL_SDK_VERSION for all packages where
this is possible without breaking the build, and
LOCAL_PRIVATE_PLATFORM_APIS := true otherwise.

Setting one of these two will be made required soon, and this
is a change in preparation for that. Not setting LOCAL_SDK_VERSION
makes the app implicitly depend on the bootclasspath, which is
often not required. This change effectively makes depending on
private apis opt-in rather than opt-out.

Test: make relevant packages

Added UserRestrinctionListener for turning the service off one the
DISALLOW_CONFIG_TETHERING is on into Tethering.  Added notification
about
tethering being turned off. Also added Unit Tests to test the
functionality
of the UserRestrictionListener added.

Bug: 27936525
Test: Turn the tehering service on (either wifi, usb or bluetooth).
Automatically the system should send a notification about the service
being active.Close settings from recents. From TestDPC User Restrictions
switch on DISALLOW_CONFIG_TETHERING. The tethering should be turned off
and a notification should appear informing that the service is inactive.

Use setAvrcpAbsoluteVolume() instead of adjustAvrcpAbsoluteVolume in
adjust stream volume in order to better sync device volume and remote
Bluetooth device volume. This will allow Bluetooth to avoid calculating
its own volume step size.

Bug: 68812037
Test: Connect to device that supports Absolute Volume and see that
      volume changed occur when changing volume on device.

This dependency is no longer required: it was added
for libcore when libcore was implemented in terms of
com.icu classes. libcore has since moved to android.icu
(in core-libart) and so the droiddoc dependency is no
longer required.

Test: make droid docs

Symptom:
RemoteFillService was crashed due to IllegalArgumentException
"Service not registered:" at onServiceConnected.

Root cause:
RemoteFillService#onServiceConnected tries to unbind the connection
if mDestroyed is flagged or mBinding is not flagged. It always fails
with IllegalArgumentException.
Both mDestroyed and !mBinding mean the connection was unbound.
You can't unbind the unbound connection. It's not allowed.

1. Added support for message priority(indicates the priority of a
   SMS to the network in the PDU) in 3gpp2
2. Added support for link control(indicates whether network can
   expect more messages or not so it can decide whether to retain
   the radio link or not) while sending multiple messages
3. Added support for validity period(indicates how much time the
   SMS is valid at the SMSC) support in 3gpp
4. Amended UT test cases for API changes and add UT validity period
   test case

Test: Verfied sending short SMS, long SMS, MMS, SMS with emoji on
      live network

addTcpStatsResult() in NetworkMetrics was not checking for the nullness
of the pendingSummary object and trying to add stats regardless.

This patch fixes addTcpStatsResult() so that it populates pendingSummary
if necessary, similarly to addConnectResult() and addDnsResult()
