An integer overflow bug in Redis version 6.0 or newer could be exploited using
the STRALGO LCS command to corrupt the heap and potentially result with remote
code execution.

An integer overflow bug in Redis 6.2 could be exploited to corrupt the heap and
potentially result with remote code execution.
The vulnerability involves changing the default set-max-intset-entries
configuration value, creating a large set key that consists of integer values
and using the COPY command to duplicate it.
The integer overflow bug exists in all versions of Redis starting with 2.6,
where it could result with a corrupted RDB or DUMP payload, but not exploited
through COPY (which did not exist before 6.2).

prefix args not all args. So when we help commands with subcommands,
all subcommands will be output.

When redis-cli was used with both -c (cluster) and -s (unix socket),
it would have kept trying to use that unix socket, even if it got
redirected by the cluster (resulting in an infinite loop).

- Immediately exit on errors that are not related to topology updates.
- Deprecates the `-e` option ( retro compatible ) and warns that we now
exit immediately on errors that are not related to topology updates.
- Fixed wrongfully failing on config fetch error (warning only). This only affects RE.
Bottom line:
- MOVED and ASK errors will not show any warning (unlike the throttled error with `-e` before).
- CLUSTERDOWN still prints an error unconditionally and sleeps for 1 second.
- other errors are fatal.

This solves an issue reported in #8712 in which a replica would bypass
the client write pause check and cause an assertion due to executing a
write command during failover.
The fact is that we don't expect replicas to execute any command other
than maybe REPLCONF and PING, etc. but matching against the ADMIN
command flag is insufficient, so instead i just block keyspace access
for now.

This prevents a case where NTP moves the system clock
forward resulting in a false detection of a busy script.

Modules event subscribers may get wrong things in notifyKeyspaceEvent callback,
such as wrong number of keys, or be able to lookup this key.
This commit changes the order to be like the one in evict.c.
Cleanup:
Since we know the key exists (it expires now), db*Delete is sure to return 1,
so there's no need to check it's output (misleading).

This scene is hard to happen. When first attempt some keys expired,
only kv position is updated not ov. Then socket err happens, second
attempt is taken. This time kv items may be mismatching with ov items.
