Analog lines do not transfer CONNECTED LINE or execute the interception macros.

Analog lines do not transfer CONNECTED LINE or execute the interception macros.

Add connected line update for sig_analog transfers and simplify the
corresponding sig_pri and chan_misdn transfer code.

Note that if you create a three-way call in sig_analog before transferring
the call, the distinction of the caller/callee interception macros make
little sense.  The interception macro writer needs to be prepared for
either caller/callee macro to be executed.  The current implementation
swaps which caller/callee interception macro is executed after a three-way
call is created.
