Should fix use-after-free when a frozen_mutation is applied to the
local shard.
Includes two adjustments to urchin collectd usage from Calle:
- Updated thrift collectd registration to use proper move semantics
- Commitlog: Fix collectd registration to use move semantics + test

boost/test/unit_test.hpp is sufficient for tests which link with boost
UTF dynamically. It includes much less headers than
boost/test/included/unit_test.hpp.
Implements a cassandra-file-compatible segmented log
of "mutations". Handles "batch" and "periodic" mode like
stock version. Also includes "dirty" management for the
interaction log/memtable.
Supports:
* add
* sync/flush
* clear dirty bits (thus discarding segments)
Many more estoric stock functions not yet implemented.
Missing: Storage management. Does not deal with total
size on disk of segments yet. Nor does it have any provisions
for dealing with active buffer bloat should async writes stall.
