I have validated that these settings closely match the existing coding
style with one major exception on `BreakBeforeBraces`, which will be
`Attach` going forward. The mixed `BreakBeforeBraces` styles in the
current codebase are hard to imitate and also very odd IMHO - see below
```
if (a == 1) { /*Attach */
}
```
```
if (a == 1 ||
b == 2)
{ /* Why? */
}
```
Please do NOT merge just yet. Will add the github action next once the
style is reviewed/approved.

When using a TLS scheme for valkey-cli and benchmark-cli compiled
without TLS, make the error message only mention the scheme used.
Before:
"valkeys:// and rediss:// are only supported when valkey-cli is compiled
with OpenSSL"
After, depending on which scheme the user tried to use:
"valkeys:// is only supported when valkey-cli is compiled with OpenSSL"
"rediss:// is only supported when valkey-cli is compiled with OpenSSL"
Follow up of #199.

This commit updates the following fields:
1. server_version -> valkey_version in server info. Since we would like
to advertise specific compatibility, we are making the version specific
to valkey. servername will remain as an optional indicator, and other
valkey compatible stores might choose to advertise something else.
1. We dropped redis-ver from the API. This isn't related to API
compatibility, but we didn't want to "fake" that valkey was creating an
rdb from a Redis version.
1. Renamed server-ver -> valkey_version in rdb info. Same as point one,
we want to explicitly indicate this was created by a valkey server.

New info information to be used to determine the valkey versioning info.
Internally, introduce new define values for "SERVER_VERSION" which is
different from the Redis compatibility version, "REDIS_VERSION".
Add two new info fields:
`server_version`: The Valkey server version
`server_name`: Indicates that the server is valkey.
Add one new RDB field: `server_ver`, which indicates the valkey version
that produced the server.
Add 3 new LUA globals: `SERVER_VERSION_NUM`, `SERVER_VERSION`, and
`SERVER_NAME`. Which reflect the valkey version instead of the Redis
compatibility version.
Also clean up various places where Redis and configuration was being
used that is no longer necessary.

This allows specifying the timeout value for opening the TCP
connection to a server. The timeout, default 0 means no limit,
depending on the OS. It can be specified using the new `-t` switch.

Let us see which version of redis this tool is part of.
Similarly to redis-cli, redis-benchmark and redis-check-rdb
redis-rdb-check and redis-aof-check are actually symlinks to redis,
so they will directly use getVersion in server, the format became:
```
{title} v={redis_version} sha={sha}:{dirty} malloc={malloc} bits={bits} build={build}
```
Move cliVersion into cli_common, redis-cli and redis-benchmark will
use it, and the format is not change:
```
{title} {redis_version} (git:{sha})
```
Technically declaring a prototype with an empty declaration has been deprecated since the early days of C, but we never got a warning for it. C2x will apparently be introducing a breaking change if you are using this type of declarator, so Clang 15 has started issuing a warning with -pedantic. Although not apparently a problem for any of the compiler we build on, if feels like the right thing is to properly adhere to the C standard and use (void).
Normally, `redis-cli` escapes non-printable data received from Redis, using a custom scheme (which is also used to handle quoted input). When using `--json` this is not desired as it is not compatible with RFC 7159, which specifies JSON strings are assumed to be Unicode and how they should be escaped.
This commit changes `--json` to follow RFC 7159, which means that properly encoded Unicode strings in Redis will result with a valid Unicode JSON.
However, this introduces a new problem with `--json` and data that is not valid Unicode (e.g., random binary data, text that follows other encoding, etc.). To address this, we add `--quoted-json` which produces JSON strings that follow the original redis-cli quoting scheme.
For example, a value that consists of only null (0x00) bytes will show up as:
* `"\u0000\u0000\u0000"` when using `--json`
* `"\\x00\\x00\\x00"` when using `--quoted-json`
- Added sanitizer support. `address`, `undefined` and `thread` sanitizers are available.
- To build Redis with desired sanitizer : `make SANITIZER=undefined`
- There were some sanitizer findings, cleaned up codebase
- Added tests with address and undefined behavior sanitizers to daily CI.
- Added tests with address sanitizer to the per-PR CI (smoke out mem leaks sooner).
Basically, there are three types of issues :
**1- Unaligned load/store** : Most probably, this issue may cause a crash on a platform that
does not support unaligned access. Redis does unaligned access only on supported platforms.
**2- Signed integer overflow.** Although, signed overflow issue can be problematic time to time
and change how compiler generates code, current findings mostly about signed shift or simple
addition overflow. For most platforms Redis can be compiled for, this wouldn't cause any issue
as far as I can tell (checked generated code on godbolt.org).
**3 -Minor leak** (redis-cli), **use-after-free**(just before calling exit());
UB means nothing guaranteed and risky to reason about program behavior but I don't think any
of the fixes here worth backporting. As sanitizers are now part of the CI, preventing new issues
will be the real benefit.
- Add `-u <uri>` command line option to support `redis://` URI scheme.
- included server connection information object (`struct cliConnInfo`),
used to describe an ip:port pair, db num user input, and user:pass to
avoid a large number of function arguments.
- Using sds on connection info strings for redis-benchmark/redis-cli

Add the -x option (Read last argument from STDIN) on redis-benchmark.
Other changes:
To be able to use the code from redis-cli some helper methods were moved to cli_common.(h|c)

This PR adds a spell checker CI action that will fail future PRs if they introduce typos and spelling mistakes.
This spell checker is based on blacklist of common spelling mistakes, so it will not catch everything,
but at least it is also unlikely to cause false positives.
Besides that, the PR also fixes many spelling mistakes and types, not all are a result of the spell checker we use.
Here's a summary of other changes:
1. Scanned the entire source code and fixes all sorts of typos and spelling mistakes (including missing or extra spaces).
2. Outdated function / variable / argument names in comments
3. Fix outdated keyspace masks error log when we check `config.notify-keyspace-events` in loadServerConfigFromString.
4. Trim the white space at the end of line in `module.c`. Check: https://github.com/redis/redis/pull/7751
5. Some outdated https link URLs.
6. Fix some outdated comment. Such as:
- In README: about the rdb, we used to said create a `thread`, change to `process`
- dbRandomKey function coment (about the dictGetRandomKey, change to dictGetFairRandomKey)
- notifyKeyspaceEvent fucntion comment (add type arg)
- Some others minor fix in comment (Most of them are incorrectly quoted by variable names)
7. Modified the error log so that users can easily distinguish between TCP and TLS in `changeBindAddr`
Disable certificate validation, making it possible to connect to servers
without configuring full trust chain.
The use of this option is insecure and makes the connection vulnerable
to man in the middle attacks.
