Permit null target on TCL connection
In previous versions of OpenOCD, it was possible to connect to the TCL
RPC interface without a current target. In `tcl_new_connection`, the
curent target would be queried by number, and the possibility of a null
current target was handled properly.
In commit bb9d9c60264a905926e0d15f84842858d0de80b7, the
`get_target_by_num` call was replaced by a `get_current_target` call,
without noticing that `get_current_target` aborts if there is no current
target, whereas `tcl_new_connection` is perfectly able to handle that
situation.
Provide a `get_current_target_or_null` function for use by consumers who
are OK with a null current target, and use it in `tcl_new_connection`.
