added L2CAP_STATE_WAIT_CONFIG_REQ_OR_SEND_CONFIG_REQ and L2CAP_STATE_WILL_SEND_CONFIG_REQ_AND_CONFIG_REQ_RSP

use L2CAP_STATE_WILL_SEND_DISCONNECT_REQUEST on client connection close

added L2CAP_STATE_WILL_SEND_CONNECTION_RESPONSE_DECLINE

added L2CAP_STATE_WILL_SEND_CONNECTION_REQUEST

forgot the l2cap_next_sig_id call

created l2cap_run() and L2CAP_STATE_WILL_SEND_DISCONNECT state

added l2cap_block_new_credits function to be used with a daemon, use BTSTACK_ACL_BUFFERS_FULL

fix emission of l2cap credits for incoming connections

deleted unused l2cap level per channel packet counting

don't crash because of bigger event

emit l2cap mtus, too

document hci_read_buffer_size result, better docuement l2cap mtu handling

more -Wstrict-prototypes fixes

assume remote side uses default mtu instead of minimum mtu for new l2cap connections

allow role switch when opening baseband for l2cap channel

note to myself

break after finding the correct channel. fixes issue #76 - thanks to murerten for this fix

consider max acl buffer in Bluetooth module as upper bound for l2cap mtu

if l2cap connection fails, drop channel immediately. if connection fails due to security block, drop link key, too

keep baseband connection during authentication

don't confuse myself

re-wrote iterate over linked list and delete element code

use constant for NR_BUFFERED_ACL_PACKETS and increase to 3

allow for 3- and 5-slot packets

allow specify MTU for outgoing l2cap connections (was 150 before)
