L2CAP dissector is missing retransmission & flow control modes (these were
introduces in BT 1.2 specification)
Configuration commands were not fully decoded because of a bigend/littleend
issue
L2CAP commands had the wrong length set to the protocol tree by reading from
the wrong buffer offset
Also the dissect_options() function consumes all remaining data in the L2CAP
packet, which prevents decoding of other commands which follow a config
request/config response in the same packet.

Test case is the H4 format log from bug 2237, so I've added that as a
dependency.
The bug and fix itself is independent.
