add gsm48_decode_bcd_number2() from osmo-msc

gsm48_decode_bcd_number() is unable to provide proper bounds validation of
input and output data, hence osmo-msc's vlr.c introduced a static
decode_bcd_number_safe() a long time ago. Move to libosmocore.

I need to use the same function to decode an MSISDN during inter-MSC Handover,
instead of making it public in osmo-msc, rather deprecate the unsafe function
and provide a safer version for all callers. Mark the old one deprecated.
