send accept synchroous connection for SCO connections

correct setup of hci_connetion for sco connection

accept connection request for SCO connections, create hci_connection_t for sco, count outgoing packets and free slots, handle num packets completed

prepare SCO sending

store num and size of SCO packets

fix regression in le_handle_advertisement_report II

fix regression in le_handle_advertisement_report

add (dummy) sco_handler

don't log baud rate change or set bd addr twice, fix wait from set bd addr complete event

send vendor specific command to set bd addr if both set and provided via bt_control_t

fix code to set connectio state to RECEIVED_DISCONNECTION_COMPLETE

streamline copyright headers

removed deprecated hci functions

avoid sending acl packets for connections where HCI_EVENT_DISCONNECTION_COMPLETE has been received

emit warning for DAEMON_EVENT_HCI_PACKET_SENT from a synchronous HCI Transport implementation

avoid var sized automatic variable in le_handle_advertisement_report

with ACL fragmentation working, usable ACL packet types depend on Host ACL buffer size and Controller features

disable attempt to encrypt connection to raise security level as it's not working

fix crash on connection failure

drop old fragments if new first fragment is received

add buffer overrun checks to ACL recombination

avoid read after free on disconnect

Fixed compiler warnings (comparision of signed with unsigned)

send remaining acl fragemnts first as they block the outgoing packet buffer

don't release packet buffer if further fragments
