The vulnerability involves changing the default set-max-intset-entries
configuration parameter to a very large value and constructing specially
crafted commands to manipulate sets
Else there is an out of bound access in syslogLevelMap.
For example if we use `serverLog(LOG_INFO,…`, later in the code
it tries to access `syslogLevelMap[LOG_INFO]`.
LOG_INFO == 6 but syslogLevelMap only have 4 elements.

This commit add zsh completions for the keydb `client`. They have contextual host completion and full argument descriptions.
Vendor-distributed completions for zsh should end up in `/usr/share/zsh/vendor-completions`, but unfortunatly I'm not familiar with the packaging method for *.deb archives, so these completions will need to be moved to the appropriate directory.

GETBIT, SETBIT may access wrong address because of wrap.
BITCOUNT and BITPOS may return wrapped results.
BITFIELD may access the wrong address but also allocate insufficient memory and segfault (see CVE-2021-32761).
This commit uses `uint64_t` or `long long` instead of `size_t`.
related https://github.com/redis/redis/pull/8096
At 32bit platform:
> setbit bit 4294967295 1
(integer) 0
> config set proto-max-bulk-len 536870913
OK
> append bit "\xFF"
(integer) 536870913
> getbit bit 4294967296
(integer) 0
When the bit index is larger than 4294967295, size_t can't hold bit index. In the past, `proto-max-bulk-len` is limit to 536870912, so there is no problem.
After this commit, bit position is stored in `uint64_t` or `long long`. So when `proto-max-bulk-len > 536870912`, 32bit platforms can still be correct.
For 64bit platform, this problem still exists. The major reason is bit pos 8 times of byte pos. When proto-max-bulk-len is very larger, bit pos may overflow.
But at 64bit platform, we don't have so long string. So this bug may never happen.
Additionally this commit add a test cost `512MB` memory which is tag as `large-memory`. Make freebsd ci and valgrind ci ignore this test.

- Introduce a new sdssubstr api as a building block for sdsrange.
The API of sdsrange is many times hard to work with and also has
corner case that cause bugs. sdsrange is easy to work with and also
simplifies the implementation of sdsrange.
- Revert the fix to RM_StringTruncate and just use sdssubstr instead of
sdsrange.
- Solve valgrind warnings from the new tests introduced by the previous
PR.

fixes test issue introduced in #9167
1. invalid reads due to accessing non-retained string (passed as unblock context).
2. leaking module blocked client context, see #6922 for info.
(cherry picked from commit a8518cce951629eaccde40fd0e51b36a5dc6321c)
Modules that use background threads with thread safe contexts are likely
to use RM_BlockClient() without a timeout function, because they do not
set up a timeout.
Before this commit, `CLIENT UNBLOCK` would result with a crash as the
`NULL` timeout callback is called. Beyond just crashing, this is also
logically wrong as it may throw the module into an unexpected client
state.
This commits makes `CLIENT UNBLOCK` on such clients behave the same as
any other client that is not in a blocked state and therefore cannot be
unblocked.

In clusterManagerCommandImport strcat was used to concat COPY and
REPLACE, the space maybe not enough.
If we use --cluster-replace but not --cluster-copy, the MIGRATE
command contained COPY instead of REPLACE.

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.

- promote the code in DEBUG PROTOCOL to addReplyBigNum
- DEBUG PROTOCOL ATTRIB skips the attribute when client is RESP2
- networking.c addReply for push and attributes generate assertion when
called on a RESP2 client, anything else would produce a broken

due to a copy-paste bug, it used to reply with null response rather than empty array.
this commit includes new tests that are looking at the RESP response directly in
order to be able to tell the difference between them.
