The latest discovered address is not used when reconnecting to devices
using resolvable private addresses, if RPA resolution offloadin is not
supported in the controller.
This patch also address the exception case where BT off is memseting
all control value while the IRK list is still being cleaned up.

* Ensure all a2dp audiopath threads are configured to high
  priority when actively streaming.
* For now set bt hc worker thread always to URGENT_AUDIO
  until new thread api can adjust thread priority dynamically.

When BT is turning off btm_ble_vendor control block is cleaned up.
So irk_entry which points to the first element of irk_list is NULL
Included a null check for irk_entry to prevent stack crash.

The userial read loop uses one global flag
to condition the serial port read and a
second global file descriptor variable that
may change from another thread underneath it.

Check the validity of the serial port file
descriptor by making a copy immediately before
the read and only proceeding if it's a valid fd.

Currently a stack restart or device reboot will overwrite existing snoop
logs when the stack restarts. This patch adds a new configuration file
parameter "BtSnoopSaveLog" that, if enabled, will cause an existing
snoop log to be renamed to "<snoop_file_name>.last" before a new snoop
log is created.

This will allow for easier debugging of crashes that involve a reboot or
stack restart.

When the LE pairing is initiated over NFC, skipping device scan, there is
no device type or address type info. We set the default as le and public.

Host can not initiate new connection when exceed controller capability
and connection then drop back to lower than the max. Controller will not
generate connection complete event when initaite LE ll connection request
failed, and host is dead loop waiting for the connection complete
then can not recover. Included a connection complete callback with failure
status when controller capability is exceeded.

To avoid premature connection notification to app, always wait for
LE read remote feature complete with success before the connection
event is sent to application.

This patch also deprecates the BTA_SKIP_BLE_READ_REMOTE_FEAT flag.
Since the remote feature request is now serialized and start encryption
won't be called until the connection is up, this flag is no longer
necessary and interferes with the new behaviour.

This is an extension of previous CL

When re-connecting to HID devices, the first reconnection immediately
after a reboot incorrectly uses the static, public Bluetooth address of
the phone/tablet as the own address.

This patch fixes the Bluetooth initialization sequence to make sure
privacy is enabled before any Bluetooth services are started.

Merge "SMP doesn't detect the event of local processing taking more than SMP timeout (30 sec)" into lmp-dev

LE link transmit quota should be calculated based on the total LE
buffer available and number of LE link that shares the buffer. Currently
it's been calculated based on the ACL buffer number and total physical
links(BR and LE), that cause the LE link transmit quota not being
done right.
Modify the link transmit quota allocation, and keep track of LE link
seperately, also keep track of round robin scheme for LE links
solving the problem.

SMP pairing failure if remote send security request before master
side receive LE link connection callback. The racing condition will
cause master side bonding failure upon ignoring remote security request
and flush out all SMP information. Retain SMP information when a
locally initiated pairing is in process solves the problem.

If the local device does not support RPA offloading, background
connections to a resolvable random address will not work. Added callback
to indicate to the application writer that the requested operation is
not supported.

Remove the link key if encryption fails due to missing key or
authentication error. When a remote device loses the bond, all
HOGP services cached should be discarded and all client configuration
descriptors needs to be re-enabled. This will ensure successful
re-connection.
