Permit a set of multiple different A5 ciphers
So far, the administrator had to pick one particular cipher which
would then be used throughout all subscribers/phones. This is a bit
impractical, as e.g. not all phones support A5/3. Extend the VTY
command syntax in a backwards-compatible way to permit for multiple
ciphers.
NOTE: Like the previous code, OsmoMSC does *not yet check* whether
the configured cipher is compatible with the MS capabilities as
reported in CLASSMARK! The network hence might choose an algorithm
not supported by the phone. Fixing this is subject to another patch.
Closes: OS#2460
