The REPLCONF command is an internal command (not designed to be directly used by normal clients) that allows a slave to set some replication related state in the master before issuing SYNC to start the replication. The initial motivation for this command, and the only reason currently it is used by the implementation, is to let the slave instance communicate its listening port to the slave, so that the master can show all the slaves with their listening ports in the "replication" section of the INFO output. This allows clients to auto discover and query all the slaves attached into a master. Currently only a single option of the REPLCONF command is supported, and it is called "listening-port", so the slave now starts the replication process with something like the following chat: REPLCONF listening-prot 6380 SYNC Note that this works even if the master is an older version of Redis and does not understand REPLCONF, because the slave ignores the REPLCONF error. In the future REPLCONF can be used for partial replication and other replication related features where there is the need to exchange information between master and slave. NOTE: This commit also fixes a bug: the INFO outout already carried information about slaves, but the port was broken, and was obtained with getpeername(2), so it was actually just the ephemeral port used by the slave to connect to the master as a client.

In order to implement reply buffer limits introduced in 2.6 and useful to close the connection under user-selected circumastances of big output buffers (for instance slow consumers in pub/sub, a blocked slave, and so forth) Redis takes a counter with the amount of used memory in objects inside the output list stored into c->reply. The computation was broken in the function setDeferredMultiBulkLength(), in the case the object was glued with the next one. This caused the c->reply_bytes field to go out of sync, be subtracted more than needed, and wrap back near to ULONG_MAX values. This commit fixes this bug and adds an assertion that is able to trap this class of problems. This problem was discovered looking at the INFO output of an unrelated issue (issue #547).

1) sendReplyToClient() now no longer stops transferring data to a single client in the case we are out of memory (maxmemory-wise). 2) in processCommand() the idea of we being out of memory is no longer the naive zmalloc_used_memory() > server.maxmemory. To say if we can accept or not write queries is up to the return value of freeMemoryIfNeeded(), that has full control about that. 3) freeMemoryIfNeeded() now does its math without considering output buffers size. But at the same time it can't let the output buffers to put us too much outside the max memory limit, so at the same time it makes sure there is enough effort into delivering the output buffers to the slaves, calling the write handler directly. This three changes are the result of many tests, I found (partially empirically) that is the best way to address the problem, but maybe we'll find better solutions in the future.

Use less memory when emitting the protocol, by using more shared objects for commonly emitted parts of the protocol.

asyncCloseClientOnOutputBufferLimitReached() now ignores clients with REDIS_CLOSE_ASAP flag already set. Return value of the function changed from int to void since it is not used. Fixed logging of the client scheduled to be closed.

Protections against protocol desyncs, leading to infinite query buffer growing, due to nul-terms in specific bytes of the request or indefinitely long multi bulk or bulk count strings without newlines. This bug is related to Issue #141 as well.
