hci: check if Read Remote Extended Features Command is implemented

GAP: gap_set_security_level sets required security level for incoming and outgoing connections

hci: release outgoing packet buffer if hci command is skipped

btstack_util: provide btstack_replace_bd_addr_placeholder

hci: only update shortened and complete local name items in provided EIR data

hci: limit device name by buffer len for write local name and write eir data

hci: introduce EXTENDED_INQUIRY_RESPONSE_DATA_LEN

hci: implement ENABLE_LE_LIMIT_ACL_FRAGMENT_BY_MAX_OCTETS

hci: emit dedicated bonding complete before disconnection complete

hci: handle hci_create_connection triggered in disconnection complete event

hci: handle gap_connect triggered by disconnection complete event

hci: allow to specify HCI_RESET_RESEND_TIMEOUT_MS from btstack_config.h

hci: reduce comparison to handle event, extract handle_event_for_current_stack_state

hci: extract hci_initializing_event_handler_command_completed

hci: reduce comparisons to process outgoing hci commands

hci: split hci_run into multiple sub statemachines

chipset/bcm: wait 300 ms after PatchRAM update in hci.c to assert Controller is ready

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

hci: fix gap_stop_scan - regression from 3251a10

test/gap: unit test for gap le scanning

hci: fix LE-only build

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

gap: fixed gap_set_scan_parameters() if issued right before gap_start_scan() - issue #275

test/fuzz: setup controller info to allow sending, set conn role as slave, cover more states

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