A5 support for RSL and 04.08 (not used yet)
This just adds the 04.08 and RSL bits for A5, but not the logic
for performing authentication.
The caller would first set lchan->encr and then call
gsm48_send_rr_ciph_mode(lchan), which encapsulates the 04.08
CIPHERING MODE COMMAND into a RSL ENCRYPTION COMMAND and sends it
to the BTS for execution + forwarding.
