Cluster leaks memory while connecting due to missing freeaddrinfo()
(Commit modified by @antirez. The freeaddrinfo() call was misplaced so
in case of no address was bound, the memory leak was still there).
Closes#1801

Previously redis-cli would happily show "-1" or "99999"
as valid DB choices.
Now, if the SELECT call returned an error, we don't update
the DB number in the CLI.

Previously, if you did SELECT then AUTH, redis-cli
would show your SELECT'd db even though it didn't
happen.
Note: running into this situation is a (hopefully) very limited
used case of people using multiple DBs and AUTH all at the same
time.

Replica migration algorithm modified so that slaves never try to migrate
to masters that were never configured to have slaves in the past.
We want the algorithm to take care of masters that remained without
*working* slaves, but that used to have slaves according to the cluster
configuration.

The original code was modified to handle signed integers, reformetted to
fit inside the Redis code base, and was stress-tested with a program
in order to validate the implementation against snprintf().
Redis was measured to be measurably faster from the point of view of
clients in real-world operations because of this change, since sometimes
number to string conversion is used extensively (for example every time
a GET results into an integer encoded object to be returned to the
user).
