Permit 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.
The bit-mask of permitted ciphers from the MSC (sent in ASSIGNMENT
COMMAND) is intersected with the vty-configured mask a the BSC.
Finally, the best (highest) possible cipher is chosen.

Closes: OS#2461
