rename RSL_ENC_ALG_A5 to ALG_A5_NR_TO_RSL, clarify
The naming confused me so that I wrote buggy code again. Hopefully this
clarifies which representations the code paths are using.
In the macro code, highlight the error case of n <= -1 explicitly.
Also add ALG_A5_NR_TO_PERM_ALG_BITS. I need the 1<<n case in an
upcoming patch.
