Some inactive devices can't send hung up key to host when
HFP connected and active call exist.
And other inactive devices can send hung up call by
sending hung up command.

Solution: To keep consistency of this behavior, 
only allow active BT device to hung up call.

Test: Active device can hung up call and inactive can't hung up

event_finish_startup and startup_timer_expired can race, leading one of
them to try to use startup_future when it is NULL.

Check startup_future still exists before using it.

Right now we often get this error in logs:

E bt_btif_gattc: btif_gattc_upstreams_evt: Unhandled event (7)!

This is often misinterpreted during log analysis as error, where this
really means just uninteresting event we don't want to handle.

Bug: http://b/79419131

Lld, which is the default linker for the platform, is able to resolve
symbols across libraries irrespective of the order they appear in the
command line.  This was not the case for ld.gold and other linkers.
Unfortunately, there are some targets that still rely on ld.gold
(pgo-taimen-config1 in internal release branch being one of
them).

With http://aosp/721652, libbt-stack should be added before libbt-common
so MessageLoopThread::~MessageLoopThread is resolved correctly.  If not,
the following error is reported by gold:

system/bt/stack/btu/btu_init.cc:41: error: undefined reference to
'bluetooth::common::MessageLoopThread::MessageLoopThread(std::__1::basic_string<char,
std::__1::char_traits<char>, std::__1::allocator<char> > const&)'

* Replace OSI thread with MessageLoopThread in
  - btif_a2dp_source (A2DP encoding thread)
  - btif_core (JNI thread)
  - btu_init (BTA thread)
  - hci_layer (HCI thread)
  - module (module bring up thread)
  - various unit test threads
* Code that uses reactor from OSI thread is not replaced in this change
  because they need to move from using reactor to message loop first
* Main difference:
  - HCI layer no longer has access to mutex protecting message loop
    set up and tear down. Messages posted to thread after ShutDown()
    is called become no-op
  - In all cases QuitClosure() is used instead of QuitWhenIdleClosure().
    This means that we will never force kill a thread. An infinite loop
    will delay the shutdown of Bluetooth stack.
* do_in_hci_thread is actually do_in_bta_thread
* Move the definition of do_in_bta_thread from bta to btu since btu is
  where the thread actually lives
* Remove bta_closure_api.h and replace it with stack/include/btu.h
* Remove header inclusion in bta_sys.h and include stack/include/btu.h
  in individual compilation units
* Fixed a bug in btif_cleanup_bluetooth where btif_jni_disassociate()
  was not called on the JNI thread
* Make setting real time priority a requirement
* Crash during the following scenario:
  - When btif_profile_queue cleanup failed to be scheduled on JNI thread
  - When A2DP encoder thread failed to gain real time priority
  - When BTA thread failed to start up
  - When BTA thread failed to gain real time priority
  - When BTA thread failed to schedule its first callback
* Turn off Bluetooth in the following scenario:
  - When HCI thread failed to gain real time priority
  - When bt_workqueue thread failed to gain real time priority

Use case:
Run PTS test cases TP/LE/CFC/BV-10-C to BV-16-C

Steps:
1. These test cases executed with two DUT as PTS support not available
2. Set desired security level on DUT and Remote with tool
3. Initiate LE COC connection request from DUT

Failure:
LE COC connection accepted though even remote security are not met.

Fix:
Added security handling for COC connection

Test: Ran sl4a test for BleCocTest

Reason: When the BT device name is updated is getting saved to the
config data pointer but not to the persistent data (i.e. bt_config.conf).
So, when the reboot is happening it is not able to get the updated device
name from the persistent data (i.e. bt_config.conf) as during reboot
bt_config_flush is not called.

Fix: Saving the BT Device name to persistent data using btif_config_flush
once it is set.

Test: Manual Reboot test
