sm: extract sm_start_calculating_ltk_from_ediv_and_rand

sm: derive BR/EDR Link Key from LE LTK established via LE Secure Connection

sm: use LE Random for initiator/jw_nk

sm: fix local nonce generation

sm: use state var to track DHKEY_CHECK_COMMAND received

sm: use AES CMAC Engine to calculate g2 for numeric comparison

sm: use AES CMAC Engine to calculate f5 for dhkey check verification

sm: use AES CMAC Engine to calculate f6 for dhkey check verification

sm: prepare dhkey check to use AES CMAC Engine

sm: use AES Engine for f4 (confirm validation)

sm: use AES Engine for f4

sm: use SM_SC_ for SC states

sm: support SC Passkey Entry

sm: support Numeric Comparison

sm: calculate DHKey, LTK, and DHKey Check values. Require only Encryption in example

sm: answer public key command in responder role

hci: enable Default Erroneous Data Reporting for SCO over HCI

Merge branch 'master' into develop

hci: use btstack_packet_handler_t for acl and sco callbacks

sm: use uint8_t[7] instead of struct for sm_pairing_packet_t to avoid to depend on packed structs

sm: use uint8_t[7] instead of struct for sm_pairing_packet_t to avoid to depend on packed structs

h5: add fixed to handle H5 state reset after CSR Warm Boot

hci: add hci_request_sco_can_send_now_event

posix: use ms timeouts in run loop and also in hci.c
