0583a04969 Bluedroid stack dynamic allocation changes to optimise DRAM usage
Structures allocated dynamically:
tACL_CONN, tBTM_PM_MCB, tBTM_SEC_DEV_REC, tGATT_TCB, tGATT_CLCB, tL2C_LCB, tL2C_CCB, tSDP_RECORD
Total dynamic allocation size ~19KB.
Peak dram usage reduced by ~12KB when in BT classic + BLE scenario(1 a2dp sink + 1 BLE gatt server)

e3350e7861 Bluedroid: Authentication fixes in Legacy and Secure Connection.
Prevent a remote device from doing a Bluetooth Impersonation Attack
(BIAS) by:

- Preventing remote device to downgrade secure connection
feature mask. Secure connection feature mask should remain same or
increase to enabled in link key generation and authentication.

- Doing a mutual authentication during Legacy Authentication.
