Calle Wilund 054f9ed082 Initial commit log support. ...

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.

[avi: adjust for future<>::rescue() removal]
