libmsc: Track and update the location update expiry
Set the subscriber expiry timeout to twice the duration of the location
update period and provide functions subscr_expire() and
db_subscriber_expire() to mark subscribers offline that have missed two
location update periods.
This patch increases the DB revision to 3, so the hlr will be
incompatible with prior versions.
We should allow 0 for T3212 as well to disable the location update
period. In that case we will need a way to indicate that in the
database.
