set le scan parameters during init

rewrote le_central_connect_cancel, fix gap_disconnect again

emit disconnection_complete on gap_disconnect

avoid sending HCI Disconnect Complete twice

Reset HCI state when rebooting Bluetooth

fix ad report data

use single gatt_complete_event (handle, status)

assert le connection on le_connect, implement le_central_connect_cancel

prepare gap_le_connect_cancel command

use LE buffers as main buffers when no classic buffers exist, e.g. on a LE single mode chip

add hci_non_flushable_packet_boundary_flag_supported

only start le scan if not already scanning, only stop le scan if not idle

don't flip bd_addr in gap adv events, trigger hci_run on le_connect, improve debug output

wrap LE code in HAVE_BLE condition

define daemon commands for gap le scan and le connect, define gap events

ble client: moved disconnect to hci

ble client: connect functionality moved to hci

ble client: implemented emit hci advertisement

ble client: scanning functionality moved to hci

track Bluetooth Device Address Type in hci_connection_t struct

added hci_release_packet_buffer() and l2cap_release_packet_buffer()

rename hci_get_outgoing_acl_packet_buffer into hci_get_outgoing_packet_buffer

add asserts to check if buffer was reserved before calling send prepared

more use of hci_can_send_packet_now_using_packet_buffer

add flag to track if hci packet buffer is reserved
