Upgrade urgency: SECURITY, contains fixes to security issues.

Security Fixes:

(CVE-2021-41099) Integer to heap buffer overflow handling certain string
commands and network payloads, when proto-max-bulk-len is manually configured
to a non-default, very large value [reported by yiyuaner].
(CVE-2021-32762) Integer to heap buffer overflow issue in redis-cli and
redis-sentinel parsing large multi-bulk replies on some older and less common
platforms [reported by Microsoft Vulnerability Research].
(CVE-2021-32687) Integer to heap buffer overflow with intsets, when
set-max-intset-entries is manually configured to a non-default, very large
value [reported by Pawel Wieczorkiewicz, AWS].
(CVE-2021-32675) Denial Of Service when processing RESP request payloads with
a large number of elements on many connections.
(CVE-2021-32672) Random heap reading issue with Lua Debugger [reported by
Meir Shpilraien].
(CVE-2021-32628) Integer to heap buffer overflow handling ziplist-encoded
data types, when configuring a large, non-default value for
hash-max-ziplist-entries, hash-max-ziplist-value, zset-max-ziplist-entries
or zset-max-ziplist-value [reported by sundb].
(CVE-2021-32627) Integer to heap buffer overflow issue with streams, when
configuring a non-default, large value for proto-max-bulk-len and
client-query-buffer-limit [reported by sundb].
(CVE-2021-32626) Specially crafted Lua scripts may result with Heap buffer
overflow [reported by Meir Shpilraien].
Bug fixes that involve behavior changes:

GEO* STORE with empty source key deletes the destination key and return 0 (#9271)
Previously it would have returned an empty array like the non-STORE variant.
PUBSUB NUMPAT replies with number of patterns rather than number of subscriptions (#9209)
This actually changed in 6.2.0 but was overlooked and omitted from the release notes.
Bug fixes that are only applicable to previous releases of Redis 6.2:

Fix CLIENT PAUSE, used an old timeout from previous PAUSE (#9477)
Fix CLIENT PAUSE in a replica would mess the replication offset (#9448)
Add some missing error statistics in INFO errorstats (#9328)
Other bug fixes:

Fix incorrect reply of COMMAND command key positions for MIGRATE command (#9455)
Fix appendfsync to always guarantee fsync before reply, on MacOS and FreeBSD (kqueue) (#9416)
Fix the wrong mis-detection of sync_file_range system call, affecting performance (#9371)
CLI tools:

When redis-cli received ASK response, it didn't handle it (#8930)
Improvements:

Add latency monitor sample when key is deleted via lazy expire (#9317)
Sanitize corrupt payload improvements (#9321, #9399)
Delete empty keys when loading RDB file or handling a RESTORE command (#9297, #9349)
