Description

In libvlr, we (will) keep every subscriber in RAM as long as it still has valid auth tuples (3GPP TS 33.102 Annex C.2.3).
Most subscribers will still have auth tuples left upon detaching, so we would store all subscribers.
Storing numerous subscribers in a linear list is inefficient, implement a hash table for faster access times.
