read buffer size on hci init

use buffers of size 1021 to fit 3-DH5 ACL packets

use buffers of size 1021 to fit 3-DH5 ACL packets, check buffer for SDP responses

use single packet handler per protocol layer: hci

add sdp_register_service_record, sdp_unregister_service_record commands

need both current position and l2cap lenght

add buffer to hci_connection_t to allow for ACL recombination

added non-working l2cap_handle_connection_request

added cmds and events for incoming connections

also provide OGF for Link Policy commands

added iPhone Bluetooth toggle functions

added btstack_get_version

renamed timer_t to timer_source_t to avoid conflict with timer_t in /usr/include/time.h in Linux

prepend all source files with 'new BSD' copyright header

removed internal functions from hci_cmds.h, more clean ups

clean up command names and headers

organize headers: e.g. use <btstack/btstack.h> instead of "btstack.h"

check BlueTool for error codes, emit HCI_EVENT_POWERON_FAILED event

trace Bluetooth status in daemon

automatic HCI link disconnect

improve hci connection handling -> suppress create connection requests for connections already open and just emit connection complete event

moved l2cap state machine to l2cap.c. added 'channel' parameter to packet header for socket communications. removed unused functions. dispatch btstack commands in daemon.c. renamed non-HCI commands

implement power control by client (only single user mode yet) with hci_set_power_mode command

keep track of HCI connections

added functions to get connectinon_t for a given connection handle or a bd_addr
