Convert check-dump to Redis check-rdb mode
redis-check-dump is now named redis-check-rdb and it runs as a mode of redis-server instead of an independent binary. You can now use 'redis-server redis.conf --check-rdb' to check the RDB defined in redis.conf. Using argument --check-rdb checks the RDB and exits. We could potentially also allow the server to continue starting if the RDB check succeeds. This change also enables us to use RDB checking programatically from inside Redis for certain failure conditions.
