In activeDefragSdsListAndDict when dict_val_type is DEFRAG_SDS_DICT_VAL_VOID_PTR, it should update de->v.val not ln->value.
Because this code path will never be executed, so this bug never happened.
In some scenarios, such as remote backup, we only want to get remote
redis server db snapshot. Currently, redis-cli acts as a replica and
sends SYNC to redis, but redis still accumulates replication buffer
in the replica client output buffer, that may result in using vast
memory, or failing to transfer RDB because of client-output-buffer-limit.
In this commit, we add 'replconf rdb-only 0|1', redis doesn't send
incremental replication buffer to them if they send 'replconf rdb-only 1',
so we can reduce used memory and improve success of getting RDB.

It was confusing as to why these don't return a map type.
the reason is that order matters, so we need to make sure the client
library knows to respect it.
Added comments in the implementation and tests to cover it.

This commit fixes a well known and an annoying issue in Sentinel mode.
Cause of this issue:
Currently, Redis rewrite process works well in server mode, however in sentinel mode,
the sentinel config has variant semantics for different configurations, in example configuration
https://github.com/redis/redis/blob/unstable/sentinel.conf, we put comments on these.
However the rewrite process only treat the sentinel config as a single option. During rewrite
process, it will mess up with the lines and comments.
Approaches:
In order to solve this issue, we need to differentiate different subconfig options in sentinel separately,
for example, sentinel monitor <master-name> <ip> <redis-port> <quorum>
we can treat it as sentinel monitor option, instead of the sentinel option.
This commit also fixes the dependency issue when putting configurations in sentinel.conf.
For example before this commit,we must put
`sentinel monitor <master-name> <ip> <redis-port> <quorum>` before
`sentinel auth-pass <master-name> <password>` for a single master,
otherwise the server cannot start and will return error. This commit fixes this issue, as long as
the monitoring master was configured, no matter the sequence is, the sentinel can start and run properly.

some tests use attach_to_replication_stream to watch what's propagated
to replicas, but in some cases the periodic ping may slip in and fail
the test.
we disable that ping by setting the period to once an hour (tests should
not run for that long).
other change is so that the next time this oom-score-adj test fails,
we'll see the value (assert_equals prints it)

BLPOP and other blocking list commands can only block on empty keys
and LPUSH only wakes up clients when the list is created.
Using the module API, it's possible to block on a non-empty key.
Unblocking a client blocked on a non-empty list (or zset) can only
be done using RedisModule_SignalKeyAsReady(). This commit tests it.

The flag should be set before TLS negotiation begins to avoid a race
condition where a fork+exec before it is completed ends up leaking the
file descriptor.

Fixes a regression introduced due to a new (safer) way of rewriting configuration files. In the past the file was simply overwritten (same inode), but now Redis creates a new temporary file and later renames it over the old one.
The temp file typically gets created with 0600 permissions so we later fchmod it to fix that. Unlike open with O_CREAT, fchmod doesn't consider umask so we have to do that explicitly.
Fixes#8369

the test was misleading because the module would actually woke up on a wrong type and
re-blocked, while the test name suggests the module doesn't not wake up at all on a wrong type..
i changed the name of the test + added verification that indeed the module wakes up and gets
re-blocked after it understand it's the wrong type
