Update databases/redis to 3.0.5.

--[ Redis 3.0.5 ] Release date: 15 Oct 2015

Upgrade urgency: MODERATE, the most important thing is a fix in the replication
                 code that may make the slave hanging forever if the master
                 remains with an open socket even if it is no longer able to
                 reply.

* [FIX] MOVE now moves the TTL as well. A bug lasting forever... finally
        fixed thanks to Andy Grunwald that reported it.
        (reported by Andy Grunwald, fixed by Salvatore Sanfilippo)
* [FIX] Fix a false positive in HSTRLEN test.
* [FIX] Fix a bug in redis-cli --pipe mode that was not able to read back
        replies from the server incrementally. Now a mass import will use
        a lot less memory, and you can use --pipe to do incremental streaming.
        (reported by Twitter user @fsaintjacques, fixed by Salvatore
        Sanfilippo)
* [FIX] Slave detection of master timeout. (fixed by Kevin McGehee, refactoring
        and regression test by Salvatore Sanfilippo)

* [NEW] Cluster: redis-trib fix can fix an additional case for opens lots.
        (Salvatore Sanfilippo)
* [NEW] Cluster: redis-trib import support for --copy and --replace options

--[ Redis 3.0.4 ] Release date: 8 Sep 2015

Upgrade urgency: HIGH for Redis and Sentinel. However note that in order to
                 fix certain replication bugs, the replication internals were
                 modified in a very heavy way. So while this release is
                 conceptually saner, it may contain regressions. For this
                 reason, before the release, QA activities were performed by
                 me (antirez) and Redis Labs and no evident bug was found.

* [FIX] A number of bugs related to replication PSYNC and the (yet experimental)
        diskless replication feature were fixed. The bugs could lead to
        inconsistency between masters and slaves. (Salvatore Sanfilippo, Oran
        Agra fixed the issue found by Yuval Inbar)
* [FIX] A replication bug in the context of PSYNC partial resynchonization was
        found and fixed. This bug happens even when diskless replication is off
        in the case different slaves connect at different times while the master
        is creating an RDB file, and later a partial resynchronization is
        attempted by a slave that connected not as the first one. (Salvatore
        Sanfilippo, Oran Agra)
* [FIX] Chained replication and PSYNC interactions leading to potential stale
        chained slaves data set, see issue #2694. (Salvatore Sanfilippo fixed
        an issue reported by "GeorgeBJ" user at Github)
* [FIX] redis-cli --scan iteration fixed when returned cursor overflows
        32 bit signed integer. (Ofir Luzon, Yuval Inbar)
* [FIX] Sentinel: fixed a bug during the master switch process, where for a
        failed conditional check, the new configuration is rewritten, during
        a small window of time, in a corrupted way where the master is
        also reported to be one of the slaves. This bug is rare to trigger
        but apparently it happens in the wild, and the effect is to see
        a replication loop where the master will try to replicate with itself.
        The bug was found by Jan-Erik Rediger using a static analyzer and
        fixed by Salvatore Sanfilippo.
* [FIX] Sentinel lack of arity checks for certain commands.
        (Rogerio Goncalves, Salvatore Sanfilippo)

* [NEW] Replication internals rewritten in order to be more resistant to bugs.
        The replication handshake in the slave side was rewritten as a non
        blocking state machine. (Salvatore Sanfilippo, Oran Agra)
* [NEW] New "replication capabilities" feature introduced in order to \ 
signal
        from the master to the slave what are the features supported, so that
        the master can choose the kind of replication to start (diskless or
        not) when master and slave are of different versions. (Oran Agra,
        Salvatore Sanfilippo)
* [NEW] Log clients details when SLAVEOF command is received. (Salvatore
        Sanfilippo with inputs from Nick Craver and Marc Gravell).
