l2cap.c 1.94 1.95=20=20=20=20=20=20=20=20=20=20=20=20
The accompanying log:
* added usage of l2ca_wait / l2ca_wakeup which blocks on a=20
connection until a response is received or the connection times out.
* removed do_cmd_backup, use blocking calls in calling function instead
* fixed l2cap_config_rsp with options / pending response /=20
not accepted config options
* fixed bug when sending back responses and con->hci_hdl not yet set
* added flags in l2cap_con struct to handle blocking calls and signalling/
result codes to upper layers.=20
* now handles conf resp flag (fragmented options)
* fixed RTX/ERTX timer handling
* removed l2cap_disconnect_wq
* added l2ca_timeoutind
* lots of minor changes and cleanup

l2cap.c 1.98 1.99=20=20=20=20=20=20=20=20=20=20=20=20
The accompanying log:
* fixed return code when waking up wait queue (SIG_CONRSP)
* added conf_req_sent
* fixed auto shutdown of l2cap cons (currently not used)
* added l2ca_wait after l2cap_connect_req when baseband exists
* fixed bug when calculating new timer interval
* fixed usermode problems with timer
* cleanup & minor changes

l2cap.c 1.99 1.100=20=20=20=20=20=20=20=20=20=20=20
The accompanying log:
* Made local functions static.
* insert_upper() now returns -ENOMEM if memory allocation failed.
* Changed a number of "return -1;" to return something more appropriate.
* Replaced all FNC and function names in strings with __FUNCTION__.
