"Fixes #884Fixes#895
Also at seastar-dev: calle/truncate_more
1.) Change truncation records to be stored with IDL serialization
2.) Fix db::serializers encoding of replay_position
3.) Detect attempted reading of Origin truncation records, and instead
of crashing, ignore and warn.
4.) Change truncation time stamps to be generated per-shard, _after_
CF flush is done, otherwise data in memtables at flush would be
retained/replayed on next start. Retain the highest time stamp
generated.
Note for (3): This patch set does _not_ clear out origin records
automatically. This because I feel that is a somewhat drastic and
irreversible thing to do. If we want to avail the user of a means
to get rid of the (3) warning, we should probably tell him to either
use cqlsh, or add an API call for this, so he can do it explicitly.

There are only two messages: prepare_message and outgoing_file_message.
Actually only the prepare_message is the message we send on wire.
Flatten the namespace.
This is a definition example for gossip_digest_ack with all its sub
classes.
It can be used by the code generator to create the serializer and
deserializer functions.
