d03cea5e36 Code simplifications. 
1. Sets do not use anymore redis encoding constants in our codebase.
2. rdb_save serializes now expiry information as well.
3. db_slice provides a simplified api to translate from absolute time to ExpirePeriod.
4. common_types.h is renamed to common.h. cached memory usage variables are moved there.

fa70267729 Add ZRANK,ZCOUNT,ZREVRANK. 
1. Fix #12 - return number of added items for non-increment usecase.
2. Fix #15 - fix double precision response. I use a different printing algorithm that of Redis
   therefore there could be string differences between 2 systems. However, both replies should
   be equivalent numerically.
3. Fix #13.  Reject ZADD with LT and GT options together.
4. Fix #11 - return correct error when parsing invalid scores.

e29f76ad4d Implement the initial version of PUBSUB. 
There are some things left to polish, mainly around
processing a subset of commands while being blocked in a subscribed state.
Also I need to solve the issue of atomic replies when publishing messages in parallel with
processing the whitelisted commands in a subscribed state.
