Add reverse history search in redis-cli (linenoise) (#12543)

added reverse history search to redis-cli, use it with the following:

* CTRL+R : enable search backward mode, and search next one when
pressing CTRL+R again until reach index 0.
```
127.0.0.1:6379> keys one
127.0.0.1:6379> keys two
(reverse-i-search): # press CTRL+R
(reverse-i-search): keys two # input `keys`
(reverse-i-search): keys one # press CTRL+R again
(reverse-i-search): keys one # press CTRL+R again, still `keys one` due to reaching index 0
(i-search): keys two # press CTRL+S, enable search forward
(i-search): keys two # press CTRL+S, still `keys one` due to reaching index 1
```

* CTRL+S : enable search forward mode, and search next one when pressing
CTRL+S again until reach index 0.
```
127.0.0.1:6379> keys one
127.0.0.1:6379> keys two
(i-search): # press CTRL+S
(i-search): keys one # input `keys`
(i-search): keys two # press CTRL+S again
(i-search): keys two # press CTRL+R again, still `keys two` due to reaching index 0
(reverse-i-search): keys one # press CTRL+R, enable search backward
(reverse-i-search): keys one # press CTRL+S, still `keys one` due to reaching index 1
```

* CTRL+G : disable
```
127.0.0.1:6379> keys one
127.0.0.1:6379> keys two
(reverse-i-search): # press CTRL+R
(reverse-i-search): keys two # input `keys`
127.0.0.1:6379> # press CTRL+G
```

* CTRL+C : disable
```
127.0.0.1:6379> keys one
127.0.0.1:6379> keys two
(reverse-i-search): # press CTRL+R
(reverse-i-search): keys two # input `keys`
127.0.0.1:6379> # press CTRL+G
```

* TAB : use the current search result and exit search mode
```
127.0.0.1:6379> keys one
127.0.0.1:6379> keys two
(reverse-i-search): # press CTRL+R
(reverse-i-search): keys two # input `keys`
127.0.0.1:6379> keys two # press TAB
```

* ENTER : use the current search result and execute the command
```
127.0.0.1:6379> keys one
127.0.0.1:6379> keys two
(reverse-i-search): # press CTRL+R
(reverse-i-search): keys two # input `keys`
127.0.0.1:6379> keys two # press ENTER
(empty array)
127.0.0.1:6379>
```

* any arrow key will disable reverse search

your result will have the search match bolded, you can press enter to
execute the full result

note: I have _only added this for multi-line mode_, as it seems to be
forced that way when `repl` is called

TCC: protect dictionaries from changing while accessed.

Certain Redis objects may change upon read only access. This is the
case, for instance, of hash tables, that may continue to incrementally
rehash after a rehashing operation. A similar problem also happens with
the PFCOUNT operation and other operations that may write as a side
effect of reading. In the case of PFCOUNT probably the right approach
would be to flag the command in a special way in the command table, so
that the operation is blocked as it if was a write operation.

Speedup INFO by counting client memory incrementally.

Related to #5145.

Design note: clients may change type when they turn into replicas or are
moved into the Pub/Sub category and so forth. Moreover the recomputation
of the bytes used is problematic for obvious reasons: it changes
continuously, so as a conservative way to avoid accumulating errors,
each client remembers the contribution it gave to the sum, and removes
it when it is freed or before updating it with the new memory usage.

Update PR #6537: use a fresh time outside call().

One problem with the solution proposed so far in #6537 is that key
lookups outside a command execution via call(), still used a cached
time. The cached time needed to be refreshed in multiple places,
especially because of modules callbacks from timers, cluster bus, and
thread safe contexts, that may use RM_Open().

In order to avoid this problem, this commit introduces the ability to
detect if we are inside call(): this way we can use the reference fixed
time only when we are in the context of a command execution or Lua
script, but for the asynchronous lookups, we can still use mstime() to
get a fresh time reference.

SipHash 2-4 -> SipHash 1-2.

For performance reasons we use a reduced rounds variant of
SipHash. This should still provide enough protection and the
effects in the hash table distribution are non existing.
If some real world attack on SipHash 1-2 will be found we can
trivially switch to something more secure. Anyway it is a
big step forward from Murmurhash, for which it is trivial to
generate *seed independent* colliding keys... The speed
penatly introduced by SipHash 2-4, around 4%, was a too big
price to pay compared to the effectiveness of the HashDoS
attack against SipHash 1-2, and considering so far in the
Redis history, no such an incident ever happened even while
using trivially to collide hash functions.

ARM: Avoid fast path for BITOP.

GCC will produce certain unaligned multi load-store instructions
that will be trapped by the Linux kernel since ARM v6 cannot
handle them with unaligned addresses. Better to use the slower
but safer implementation instead of generating the exception which
should be anyway very slow.

Ziplist: insertion bug under particular conditions fixed.

Ziplists had a bug that was discovered while investigating a different
issue, resulting in a corrupted ziplist representation, and a likely
segmentation foult and/or data corruption of the last element of the
ziplist, once the ziplist is accessed again.

The bug happens when a specific set of insertions / deletions is
performed so that an entry is encoded to have a "prevlen" field (the
length of the previous entry) of 5 bytes but with a count that could be
encoded in a "prevlen" field of a since byte. This could happen when the
"cascading update" process called by ziplistInsert()/ziplistDelete() in
certain contitious forces the prevlen to be bigger than necessary in
order to avoid too much data moving around.

Once such an entry is generated, inserting a very small entry
immediately before it will result in a resizing of the ziplist for a
count smaller than the current ziplist length (which is a violation,
inserting code expects the ziplist to get bigger actually). So an FF
byte is inserted in a misplaced position. Moreover a realloc() is
performed with a count smaller than the ziplist current length so the
final bytes could be trashed as well.

SECURITY IMPLICATIONS:

Currently it looks like an attacker can only crash a Redis server by
providing specifically choosen commands. However a FF byte is written
and there are other memory operations that depend on a wrong count, so
even if it is not immediately apparent how to mount an attack in order
to execute code remotely, it is not impossible at all that this could be
done. Attacks always get better... and we did not spent enough time in
order to think how to exploit this issue, but security researchers
or malicious attackers could.

Scripting: native lua.exists() implementation.

This was a test to check how much faster native implementation would be.
In initial tests it does not look like is this huge win.

After all this is at least in part obvious. Now scripting.c tries to
avoid allocations of argument vectors, and turning ":1" accumulated in
the client buffer into a Lua type is a fast operation.
