This enables use of BT_MODE_EXT_FLOWCTL with BT_MODE socketopt, in
addition to that add support for DEFER_SETUP to be used with client
sockets so they can be grouped and sent together.

BT_MODE is not compatible with L2CAP_OPTIONS so attempting to use them
both will cause an error to be returned to the applicatio.

This has been tested by introducing support for L2CAP_MODE_EXT_FLOWCTL
into l2cap-tester which now produces the following trace:

Enable ecred PDUs:
#echo 1 > /sys/module/bluetooth/parameters/enable_ecred

#sudo tools/l2cap-tester -p "L2CAP Ext-Flowctl"
