Add filter_subnet_table bif

Browse source 
This bif works similar to the matching_subnet bif. The difference is
that, instead of returning a vector of the subnets that match, we return
a filtered view of the original set/table only containing the changed
subnets.

This commit also fixes a small bug in TableVal::UpdateTimestamp
(ReadOperation only has to be called when LoggingAccess() is true).
