With the new behavior it is possible to specify just the start in the
range (the end will be assumed to be the first byte), or it is possible
to specify both start and end.
This is useful to change the behavior of the command when looking for
zeros inside a string.
1) If the user specifies both start and end, and no 0 is found inside
the range, the command returns -1.
2) If instead no range is specified, or just the start is given, even
if in the actual string no 0 bit is found, the command returns the
first bit on the right after the end of the string.
So for example if the string stored at key foo is "\xff\xff":
BITPOS foo (returns 16)
BITPOS foo 0 -1 (returns -1)
BITPOS foo 0 (returns 16)
The idea is that when no end is given the user is just looking for the
first bit that is zero and can be set to 1 with SETBIT, as it is
"available". Instead when a specific range is given, we just look for a
zero within the boundaries of the range.
This commit changes the findBigKeys() function in redis-cli.c to use the new
SCAN command for iterating the keyspace, rather than RANDOMKEY. Because we
can know when we're done using SCAN, it will exit after exhausting the keyspace.

The computation is just something to take the CPU busy, no need to use a
specific type. Since stdint.h was not included this prevented
compilation on certain systems.

Now that we have a runtime configuration system, it is very important to
be able to log how the Sentinel configuration changes over time because
of API calls.

This error was conceived for the older version of Sentinel that worked
via master redirection and that was not able to get configuration
updates from other Sentinels via the Pub/Sub channel of masters or
slaves.
This reply does not make sense today, every Sentinel should reply with
the best information it has currently. The error will make even more
sense in the future since the plan is to allow Sentinels to update the
configuration of other Sentinels via gossip with a direct chat without
the prerequisite that they have at least a monitored instance in common.

If you launch redis with `redis-server --sentinel` then
in a ps, your output only says "redis-server IP:Port" — this
patch changes the proc title to include [sentinel] or
[cluster] depending on the current server mode:
e.g. "redis-server IP:Port [sentinel]"
"redis-server IP:Port [cluster]"

The default cluster control port is 10,000 ports higher than
the base Redis port. If Redis is started on a too-high port,
Cluster can't start and everything will exit later anyway.

Report the actual port used for the listening attempt instead of
server.port.
Originally, Redis would just listen on server.port.
But, with clustering, Redis uses a Cluster Port too,
so we can't say server.port is always where we are listening.
If you tried to launch Redis with a too-high port number (any
port where Port+10000 > 65535), Redis would refuse to start, but
only print an error saying it can't connect to the Redis port.
This patch fixes much confusions.

If we can't reconfigure a slave in time during failover, go forward as
anyway the slave will be fixed by Sentinels in the future, once they
detect it is misconfigured.
Otherwise a failover in progress may never terminate if for some reason
the slave is uncapable to sync with the master while at the same time
it is not disconnected.

The code tried to obtain the configuration file absolute path after
processing the configuration file. However if config file was a relative
path and a "dir" statement was processed reading the config, the absolute
path obtained was wrong.
With this fix the absolute path is obtained before processing the
configuration while the server is still in the original directory where
it was executed.

Now it logs the file name if it is not accessible. Also there is a
different error for the missing config file case, and for the non
writable file case.
