hci: gap_set_allow_role_switch allows to prevent role switch in outgoing classic ACL connections

test/gap: unit test for gap le scanning

hci: fix compile

hci: only send HCI Read Local Encryption Key Size if supported by Controller

test/fuzz: prepare classic acl + sco incoming and ready + le ready hci connection for fuzz_hci

test/fuzz: test hci

hci_transport: remove packet type defines provided by bluetooth.h

MISRAC2012-Rule-12.1: add suggested parentheses

gap: write supervision timeout after connection complete [a2349]

gap: add gap_set_link_supervision_timeout and link_supervision_timeout in hci_stack.h [a2348]

hci: extract internal definitions from bluetooth.h

gap: support reading RSSI for Classic+LE using gap_read_rssi. Emits GAP_EVENT_RSSI_MEASUREMENT

gap: Register filter for rejecting classic connections

sm: generate local nonce for confirm value in JW+NC+PK in sc responder role

sm: remove unused states

errata-11838: validate encryption key size to emit GAP Security Level, gap_set_required_encryption_key_size allows to set the required key size

hci: read encryption key size for classic connections after encryption got enabled

hci: use 2 bytes as HCI incoming pre-buffer without Classic for GATT Client

hci: add l2cap_cid to att_server_t

hci: skip sending second baud rate change if there's no init script and no warm start

Use FILENAME_H as include guard (MISRAC2012-Rule-21.1)

hci: improved sco tx scheduling (without flow control over UART)

hci: fix sco can send now for usb transports

hci: fix compile without sco-over-hci

hci: track SCO RX times, emit SCO can send now based on RX times
