library/GSM_SystemInformation: add dec_SystemInformationSafe()
Some types of System Information (mostly the Rest Octets) are not
fully implemented, so calling the generic dec_SystemInformation()
may result in a DTE. Let's add dec_SystemInformationSafeBT() with
"prototype(backtrack)", so it would return a non-zero integer if
decoding fails. Let's add a wrapper dec_SystemInformationSafe()
that would additionally check the RR Protocol Discriminator.
