This patch adds support to send a cell's ttl as part of a query's
result. This is needed for thrift support.

This patch makes hashing for repair calculate checksums in a way that
doesn't require rebuilding whole mutation.
Unfortunately, such checksums are incompatible with the old ones so the
old way for computing checksums is preserved for compatibility reasons.

queries and the reconciliation logic abide by this limit.

This patch introduces the range_tombstone class, composed of
a [start, end] pair of clustering_key_prefixes, the type
of inclusiveness of each bound, and a tombstone.

We did the clean up in idl/gossip_digest.idl.hh, but the patch to clean
up gms/application_state.hh was never merged.
To maintain compatibility with previous version of scylla, we can not
change application_state.hh, instead change idl to be sync with
application_state.hh.

Result digest is going to be computed in query result builder and
require information not available in the query resylt. That's why the
digest now needs to be sent to the other nodes together with the result
as they won't be able compute it on their own.

The query result footprint for cassandra-stress mutation as reported
by tests/memory-footprint increased by 18% from 285 B to 337 B.
perf_simple_query shows slight regression in throughput (-8%):

"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.
