> A while ago we decided to make all functions and types keyspace local, but haven't updated our assumption in the code accordingly.
> One consequence is that in addition to {{Schema}} and {{KSMetaData}} we got ourselves a completely separate registry singleton for built-in functions, UDFs, and UDAs - the {{Functions}} class.
> The linked branch makes UDAs and UDFs be a part of {{KSMetaData}}, as they should be, and gets rid of the old {{Functions}} class.
> A new {{Functions}} class is introduced - an immutable container for a given keyspace's functions, and all the definitions are now spread between the keyspaces.
> This sneaks in a bit of {{CASSANDRA-9425}}, makes {{CASSANDRA-9367}} easier, and is a minore pre-requisite for a proper implementation of {{CASSANDRA-6717}}.
> On top of Sylvain's 8099 branch, with CASSANDRA-9542 cherry-picked.
