With this patch, the TRAU muxing code supports not just bridging only. 

A new function trau_recv_lchan() is used to link a channel to a call reference
of a transaction. (Transactions are used in later patches.) TRAU frames will
then be forwarded to the application with the given call reference (in later
patches). Also the application can send TRAU frames by using trau_send_lchan().

A new list is introduced in trau_mux.c. (upqueue_entry) All subslots
that must be sent to application are listed here.

Received TRAU frames are written in the upqueue of application
interface, if a call reference is found in the upqueue-list. If an entry
is found the ss_entry list, the TRAU frames are bridged as before. The
frames have a message type (msg_type), a call reference (callref) and a
trau frame (data). The length of trau frame is defined by the content of
the c-bits inside the frame.

There is no support for ip.access yet, as they don't use the traditional
TRAU frame format. Harald must add this in order to use application interface
with ip-access. The bridging with ip-access works as before.
