Description

EC overwrites require two new concepts:
1) Each log entry needs to include information which records which shards (shard/crush position, not osd) actually participated. We may want to play with the encoding a bit here since all replicated pool entries and many ec pool entries will have involved all shards.
2) Add logic and unit tests for PGLog.h/cc to test this new code until the rest of the pieces are in place.

We can punt on this until we actually start skipping writes to non-participating shards.
