Add new BSC RLL layer of code
A caller can call rll_establish(lchan, link_id) and a callback to the GSM RLL
code. He will get called back if the RLL link is established or receives some
error message, or the establishment times out.
We need this for proper SMS implementation, where we need to restablish a SAPI3
RLL link before transmitting the actual CP-DATA messages.
