Return a bad score when used with negative count (or count of 1), and non-ziplist encoded zset.
Also add test to validate the return value and cover the issue.

Previously, passing 0 for newlen would not truncate the string at all.
This adds handling of this case, freeing the old string and creating a new empty string.
Other changes:
- Move `src/modules/testmodule.c` to `tests/modules/basics.c`
- Introduce that basic test into the test suite
- Add tests to cover StringTruncate
- Add `test-modules` build target for the main makefile
- Extend `distclean` build target to clean modules too

Fix crash when using io-threads-do-reads and issuing CLIENT PAUSE and
CLIENT UNPAUSE.
This issue was introduced in redis 6.2 together with the FAILOVER command.

sometimes you can be very deep in the call stack, without access to argv.
once you're there you may want your reply/log to contain the command name.

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.
see #9046

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.

Fixes#6792. Added support of REDIS_REPLY_SET in raw and csv output of `./redis-cli`
Test:
run commands to test:
./redis-cli -3 --csv COMMAND
./redis-cli -3 --raw COMMAND
Now they are returning resuts, were failing with: "Unknown reply type: 10" before the change.
