The obtained process_rss was incorrect (the OS reports pages, not
bytes), resulting with many other fields getting corrupted.
This has been tested on FreeBSD but not other platforms.

When a quicklist has quicklist->compress * 2 nodes, then call
__quicklistCompress, all nodes will be decompressed and the middle
two nodes will be recompressed again. This violates the fact that
quicklist->compress * 2 nodes are uncompressed. It's harmless
because when visit a node, we always try to uncompress node first.
This only happened when a quicklist has quicklist->compress * 2 + 1
nodes, then delete a node. For other scenarios like insert node and
iterate this will not happen.

It seems like non-Linux sockets may be less greedy, resulting with more
transient client output buffers.
Haven't proven this but empirically when stressing this test on
non-Linux tends to exhibit increased mem_clients_normal values.

Scenario:
1. A module client is blocked on keys with a timeout
2. Shortly before the timeout expires, the key is being populated and signaled
as ready
3. Redis calls moduleTryServeClientBlockedOnKey (which replies to client) and
then moduleUnblockClient
4. moduleUnblockClient doesn't really unblock the client, it writes to
server.module_blocked_pipe and only marks the BC as unblocked.
5. beforeSleep kics in, by this time the client still exists and techincally
timed-out. beforeSleep replies to the timeout client (double reply) and
only then moduleHandleBlockedClients is called, reading from module_blocked_pipe
and calling unblockClient
The solution is similar to what was done in moduleTryServeClientBlockedOnKey: we
should avoid re-processing an already-unblocked client

* The `redis-cli --scan` output should honor output mode (set explicitly or implicitly), and quote key names when not in raw mode.
* Technically this is a breaking change, but it should be very minor since raw mode is by default on for non-tty output.
* It should only affect TTY output (human users) or non-tty output if `--no-raw` is specified.
* Added `--quoted-input` option to treat all arguments as potentially quoted strings.
* Added `--quoted-pattern` option to accept a potentially quoted pattern.
Unquoting is applied to potentially quoted input only if single or double quotes are used.
Fixes#8561, #8563

When the length of the quicklist is 1(only one zipmap), the rotate operation will cause
memory overlap when moving an entity from the tail of the zipmap to the head.
quicklistRotate is a dead code, so it has no impact on the existing code.

Since the API declared (as #define) in redismodule.h and uses
the CLIENT_ID_AOF that declared in the server.h, when
a module will want to make use of this API, it will get a compilation
error (module doesn't include the server.h).
The API was broken by fd914fd (failed attempt for a cleanup).
Revert to the original version of RedisModule_IsAOFClient
that uses UINT64_MAX instead of CLIENT_ID_AOF
