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.

Some Bluetooth devices - such as an Xbox One S controller (model 1708) - report more than two external features pages and are rejected immediately. Pages 1 and 2 are marked as unhandled in btm_devctl.c anyway, so there is no reason to block devices with more pages.

Future events scheduling error in case of wifi and bluetooth.
1. Improve WiFi throughput in some Classic BT scienarios(idle, inquire scan,
connected, sniff, a2dp pause, etc).
2. Support WiFi + Classic BT + BLE mesh coexistence scienario.
3. Improve WiFi scan and connect succeed ratio in coexistence scienario.
4. Do not support to choose software coexistence preference anymore for it is
determined according to coexistence scienario automatically.
components/lwip: increase TCP send buffer and receive window limitation when TCP window scale is enabled
components/ble_mesh: Fix some bugs about ble mesh
1. fix send acl pkt after ble have sent terminate ind modify min adv interval to 10ms.
- Modifies `smp_utils.c` to add check on encryption key size received from
peer.
- Modifies `esp_ble_gap_set_security_param` API to add minimum encryption key
size requirement.
