hget and hset commands using hashes internally, thus they are not using the existing write_strings() function. Limitations: - hset only supports 3 params, instead of multiple field/value list that is available in official redis-server. - hset should return 0 when the key and field already exists, but I am not sure it's possible to retrieve this information without doing read-before-write, which would not be atomic. I factorized a bit the query_* functions to reduce duplication, but I am not 100% sure of the naming, it may still be a bit confusing between the schema used (strings, hashes) and the returned format (currently only string but array should come later with hgetall).
