Normally in modern Redis you can't create zero-len lists, however it's possible to load them from old RDB files generated, for instance, using Redis 2.8 (see issue #4409). The "Right Thing" would be not loading such lists at all, but this requires to hook in rdb.c random places in a not great way, for a problem that is at this point, at best, minor. Here in this commit instead I just fix the fact that zero length lists, materialized as quicklists with the first node set to NULL, were iterated in the wrong way while they are saved, leading to a crash. The other parts of the list implementation are apparently able to deal with empty lists correctly, even if they are no longer a thing.

Since SDS v2, we no longer have a single header, so the function to rewrite the SDS in terms of the minimum space required, instead of just using realloc() and let the underlying allocator decide what to do, was doing an allocation + copy every time the minimum possible header needed to represent the string was different than the current one. This could be often a bit wasteful, because if we go, for instance, from the 32 bit fields header to the 16 bit fields header, the overhead of the header is normally very small. With this commit we call realloc instead, unless the change in header size is very significant in relation to the string length.

There was not enough sanity checking in the code loading the slots of Redis Cluster from the nodes.conf file, this resulted into the attacker's ability to write data at random addresses in the process memory, by manipulating the index of the array. The bug seems exploitable using the following techique: the config file may be altered so that one of the nodes gets, as node ID (which is the first field inside the structure) some data that is actually executable: then by writing this address in selected places, this node ID part can be executed after a jump. So it is mostly just a matter of effort in order to exploit the bug. In practice however the issue is not very critical because the bug requires an unprivileged user to be able to modify the Redis cluster nodes configuration, and at the same time this should result in some gain. However Redis normally is unprivileged as well. Yet much better to have this fixed indeed. Fix #4278.

Certain checks were useless, at the same time certain malformed inputs were accepted without problems (emtpy strings parsed as zero). Cases where strtod() returns ERANGE but we still want to parse the input where ok in getDoubleFromObject() but not in the long variant. As a side effect of these fixes, this commit fixes #4391.

This commit is a reinforcement of commit c1c99e9f. 1. Replication information can be stored when the RDB file is generated by a mater using server.slaveseldb when server.repl_backlog is not NULL, or set repl_stream_db be -1. That's safe, because NULL server.repl_backlog will trigger full synchronization, then master will send SELECT command to replicaiton stream. 2. Only do rdbSave* when rsiptr is not NULL, if we do rdbSave* without rdbSaveInfo, slave will miss repl-stream-db. 3. Save the replication informations also in the case of SAVE command, FLUSHALL command and DEBUG reload.

This commit attempts to fix a number of bugs reported in #4316. They are related to the way replication info like replication ID, offsets, and currently selected DB in the master client, are stored and loaded by Redis. In order to avoid inconsistencies the changes in this commit try to enforce that: 1. Replication information are only stored when the RDB file is generated by a slave that has a valid 'master' client, so that we can always extract the currently selected DB. 2. When replication informations are persisted in the RDB file, all the info for a successful PSYNC or nothing is persisted. 3. The RDB replication informations are only loaded if the instance is configured as a slave, otherwise a master can start with IDs that relate to a different history of the data set, and stil retain such IDs in the future while receiving unrelated writes.

A slave may be started with an RDB file able to provide enough slave to perform a successful partial SYNC with its master. However in such a case, how outlined in issue #4268, the slave backlog will not be started, since it was only initialized on full syncs attempts. This creates different problems with successive PSYNC attempts that will always result in full synchronizations. Thanks to @fdingiit for discovering the issue.
