WIP: Implement the NS Sub-Network-Service (SNS) on Gb connectdaniel/gb-sns
This change implements the use of GPRS Gb interface auto-configuration using the NS IP Sub-Network Service (SNS) procedures. It requires a (currently experimental) libosmogb in order to support this feature. Change-Id: I256b40ac592d3b6e75dd581bf7b9512f69b11e83
