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.

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 output for COMMAND command was wrong for some commands.
clients can use firstkey,lastkey,step to find (some) key name arguments, and the
"movablekeys" flag to know that they can't know all (or any) of the key name arguments.
These commands had the wrong output:
1. GEORADIUS*_RO used to have "movablekeys" (which it doesn't really need)
2. XREAD and XREADGROUP used to have (1,1,1). but that's completely wrong.
3. Z*STORE used to have (0,0,0) but it can at lest give the index of the dstkey (1,1,1)

Fix broken formatting in `RM_Call` and `RM_CreateDataType`,
`RM_SubscribeToServerEvent` (nested lists, etc. in list items).
Unhide docs of `RM_LoadDataTypeFromString` and
`RM_SaveDataTypeToString` by removing blank line between docs and
function.
Clarification added to `RM__Assert`: Recommentation to use the
`RedisModule_Assert` macro instead.
All names containing underscores (variable and macro names) are
wrapped in backticks (if not already wrapped in backticks). This
prevents underscore from being interpreted as italics in some
cases.
Names including a wildcard star, e.g. RM_Defrag*(), is wrapped in
backticks (and RM replaced by RedisModule in this case). This
prevents the * from being interpreted as an italics marker.
A list item with a sublist, a paragraph and another sublist is a
combination which seems impossible to achieve with RedCarped
markdown, so the one occurrence of this is rewritten.
Various trivial changes (typos, backticks, etc.).
Ruby script:
* Replace `RM_Xyz` with `RedisModule_Xyz` in docs. (RM is correct
when refering to the C code but RedisModule is correct in the
API docs.)
* Automatic backquotes around C functions like `malloc()`.
* Turn URLs into links. The link text is the URL itself.
* Don't add backticks inside bold (**...**)

Sentinel uses execve to run scripts, so it needs to use FD_CLOEXEC
on all file descriptors, so that they're not accessible by the script it runs.
This commit includes a change to the sentinel tests, which verifies no
FDs are left opened when the script is executed.

This was a regression from #7625 (only in 6.2 RC2).
This makes it possible again to implement blocking list and zset
commands using the modules API.
This commit also includes a test case for the reverse: A module
unblocks a client blocked on BLPOP by inserting elements using
RedisModule_ListPush(). This already works, but it was untested.

Previously invalid configuration errors were not very specific and in some cases hard to understand.
