The new command allows to change master-specific configurations
at runtime. All the settable parameters can be retrivied via the
SENTINEL MASTER command, so there is no equivalent "GET" command.

The claim about unlinking the instance from the connected hash tables
was the opposite of the reality. Also the current actual behavior is
safer in most cases, so it is better to manually unlink when needed.

The new function is used when we want to normalize an IP address without
performing a DNS lookup if the string to resolve is not a valid IP.
This is useful every time only IPs are valid inputs or when we want to
skip DNS resolution that is slow during runtime operations if we are
required to block.

Masters not understanding REPLCONF ACK will reply with errors to our
requests causing a number of possible issues.
This commit detects a global replication offest set to -1 at the end of
the replication, and marks the client representing the master with the
REDIS_PRE_PSYNC flag.
Note that this flag was called REDIS_PRE_PSYNC_SLAVE but now it is just
REDIS_PRE_PSYNC as it is used for both slaves and masters starting with
this commit.
This commit fixes issue #1488.

Now the socket is closed if anetNonBlock() fails, and in general the
code structure makes it harder to introduce this kind of bugs in the
future.
Reference: pull request #1059.

There were two problems with the implementation.
1) "save" was not correctly processed when no save point was configured,
as reported in issue #1416.
2) The way the code checked if an option existed in the "processed"
dictionary was wrong, as we add the element with as a key associated
with a NULL value, so dictFetchValue() can't be used to check for
existance, but dictFind() must be used, that returns NULL only if the
entry does not exist at all.
