SINTERSTORE would have deleted the dest key right away,
even when later on it is bound to fail on an (WRONGTYPE) error.
With this change it first picks up all the input keys, and only later
delete the dest key if one is empty.
Also add more tests for some commands.
Mainly focus on
- `wrong type error`:
expand test case (base on sinter bug) in non-store variant
add tests for store variant (although it exists in non-store variant, i think it would be better to have same tests)
- the dstkey result when we meet `non-exist key (empty set)` in *store
sdiff:
- improve test case about wrong type error (the one we found in sinter, although it is safe in sdiff)
- add test about using non-exist key (treat it like an empty set)
sdiffstore:
- according to sdiff test case, also add some tests about `wrong type error` and `non-exist key`
- the different is that in sdiffstore, we will consider the `dstkey` result
sunion/sunionstore add more tests (same as above)
sinter/sinterstore also same as above ...

When using RESP3, ZPOPMAX/ZPOPMIN should return nested arrays for consistency
with other commands (e.g. ZRANGE).
We do that only when COUNT argument is present (similarly to how LPOP behaves).
for reasoning see https://github.com/redis/redis/issues/8824#issuecomment-855427955
This is a breaking change only when RESP3 is used, and COUNT argument is present!

1. redis-cli can output --rdb data to stdout
but redis-cli also write some messages to stdout which will mess up the rdb.
2. Make redis-cli flush stdout when printing a reply
This was needed in order to fix a hung in redis-cli test that uses
--replica.
Note that printf does flush when there's a newline, but fwrite does not.
3. fix the redis-cli --replica test which used to pass previously
because it didn't really care what it read, and because redis-cli
used printf to print these other things to stdout.
4. improve redis-cli --replica test to run with both diskless and disk-based.

- networking.c addReply for push and attributes generate assertion when
called on a RESP2 client, anything else would produce a broken

A change in redis 6.2 caused redis-cli --rdb that's directed to stdout to fail because fsync fails.
This commit avoids doing ftruncate (fails with a warning) and fsync (fails with an error) when the
output file is `-`, and adds the missing documentation that `-` means stdout.

The decision to stop trimming due to LIMIT in XADD and XTRIM was after the limit was reached.
i.e. the code was deleting **at least** that count of records (from the LIMIT argument's perspective, not the MAXLEN),
instead of **up to** that count of records.

xtrimCommand call streamParseAddOrTrimArgsOrReply should use xadd==0.
When the syntax is valid, it does not cause any bugs because the params of XADD is superset of XTRIM.
Just XTRIM will not respond with error on invalid syntax. The syntax of XADD will also be accpeted by XTRIM.

When test stop 'load handler' by killing the process that generating the load,
some commands that already in the input buffer, still might be processed by the server.
This may cause some instability in tests, that count on that no more commands
processed after we stop the `load handler'
In this commit, new proc 'wait_load_handlers_disconnected' added, to verify that no more
cammands from any 'load handler' prossesed, by checking that the clients who
genreate the load is disconnceted.
Also, replacing check of dbsize with wait_for_ofs_sync before comparing debug digest, as
it would fail in case the last key the workload wrote was an overridden key (not a new one).
Affected tests
Race fix:
- failover command to specific replica works
- Connect multiple replicas at the same time (issue #141), master diskless=$mdl, replica diskless=$sdl
- AOF rewrite during write load: RDB preamble=$rdbpre
Cleanup and speedup:
- Test replication with blocking lists and sorted sets operations
- Test replication with parallel clients writing in different DBs
- Test replication partial resync: $descr (diskless: $mdl, $sdl, reconnect: $reconnect

There are two issues fixed in this commit:
1. we want to fail the EXEC command in case there is a watched key that's logically
expired but not yet deleted by active expire or lazy expire.
2. we saw that currently cache time is update in every `call()` (including nested calls),
this time is being also being use for the isKeyExpired comparison, we want to update
the cache time only in the first call (execCommand)

In aof rewrite, when parent stop sending data to child, if there is
new rewrite data, aofChildWriteDiffData write event will be installed.
Then this event is issued and deletes the file event without do anyting.
This will happen over and over again until aof rewrite finish.
This bug used to waste a few system calls per excessive wake-up
(epoll_ctl and epoll_wait) per cycle, each cycle triggered by receiving
a write command from a client.

Currently a replica is able to recover from a short read (when diskless loading
is enabled) and avoid crashing/exiting, replying to the master and then the rdb
could be sent again by the master for another load attempt by the replica.
There were a few scenarios that were not behaving similarly, such as when
there is no end-of-file marker, or when module aux data failed to load, which
should be allowed to occur due to a short read.

The `Tracking gets notification of expired keys` test in tracking.tcl
used to hung in valgrind CI quite a lot.
It turns out the reason is that with valgrind and a busy machine, the
server cron active expire cycle could easily run in the same event loop
as the command that created `mykey`, so that when they key got expired,
there were two change events to broadcast, one that set the key and one
that expired it, but since we used raxTryInsert, the client that was
associated with the "last" change was the one that created the key, so
the NOLOOP filtered that event.
This commit adds a test that reproduces the problem by using lazy expire
in a multi-exec which makes sure the key expires in the same event loop
as the one that added it.

In diskless replication, we create a read pipe for the RDB, between the child and the parent.
When we close this pipe (fd), the read handler also needs to be removed from the event loop (if it still registered).
Otherwise, next time we will use the same fd, the registration will be fail (panic), because
we will use EPOLL_CTL_MOD (the fd still register in the event loop), on fd that already removed from epoll_ctl

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).

- 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.
