LE fixes

LE fixes

- Null pointer exception check added.

An exception occurs at the memcpy in the bta_dm_gatt_disc_result.
User removed the battery on Ble device(Smart Nudge) during bonding
and connection. This exception occurs sometimes.
I used Broadcom LE Explorer to reproduce it.

- Fixed disconnect and encryption behaviour

Disconnect will now disconnect the physical link immediately when no
other application is interested in the device anymore. Also, the
connection to a remote device is now dropped if encryption fails.

- Deep copy buffers when transfering context

Certain BTA server event types require a deep copy of the request
data buffers when transfering context. Shallow copy of the pointers
involved may cause a crash when overlapping read and write requests
are received.

- 2nd encryption has not started

need to send encryption complete callback
when the encryption fail due to link drop without a complete event.
Otherwise BTA layer would not be able to clean up the status,
and no further encryption can be started.

Remove bluedroid configuration warning

This warning is fired on every full-eng build. It seems excessive
given that there are very few other warning fired on a full-eng build
and 0 seems like a reasonable goal to shoot for.

Fixed unpair and reconnect issue with certain non-pointing hid devices

Hid info would not be removed from storage if COD is
NON_KEYBOARD_NON_POINTING. Due to this the device will
be added to stack even if it is unpaired and subsequent connections
will fail.

am 6ff9944c: fix bt_hc_worker_thread() sometimes transmit more than num_hci_cmd_pkts

# Via Toshi Kikuchi
* commit '6ff9944c9dda368fd79ebdf8d6748fc4922eafec':
fix bt_hc_worker_thread() sometimes transmit more than num_hci_cmd_pkts

fix bt_hc_worker_thread() sometimes transmit more than num_hci_cmd_pkts

bt_hc_worker_thread() checks the controller's outstanding HCI
command credits (maintained in num_hci_cmd_pkts) and skips the rest
of the tx queue after it has used up the credits. But the skip
condition is not correct in the loop:

if ((tx_cmd_pkts_pending == TRUE) || (num_hci_cmd_pkts <= 0))
{
tx_cmd_pkts_pending = TRUE;
// skip the rest of the packets in the tx queue
...
}

Since num_hci_cmd_pkts doesn't change during the loop, this condition
never becomes true. As a result, all the HCI commands in the tx queue
are sent if num_hci_cmd_pkts > 0. That is why sometimes more than
num_hck_cmd_pkts are sent.

To check a correct skip condition, we should count how many HCI
command packets are being sent:

if ((tx_cmd_pkts_pending == TRUE) ||
(sending_hci_cmd_pkts_count >= num_hci_cmd_pkts))

sending_hci_cmd_pkts_count is incremented every time a HCI command is
pushed for sending. It should never go beyond num_hci_cmd_pkts.

fix too small buffer

property_get must be called with a buffer of at least
PROPERTY_VALUE_MAX len. The supplied buffer is too small.
Fixed.
