move creation of clients into the test so that it can be skipped
(cherry picked from commit cc455a710cc68d0fd8243cd1f04c5ee7332e4fdb)
- skip full units
- skip a single test (not just a list of tests)
- when skipping tag, skip spinning up servers, not just the tests
- skip tags when running against an external server too
- allow using multiple tags (split them)

Fix issues with writeConn() which resulted with corruption of the stream by leaving an extra byte in the buffer. The trigger for this is partial writes or write errors which were not experienced on Linux but reported on macOS.

When runtest-cluster, at first, we need to create a cluster use spawn_instance,
a port which is not used is choosen, however sometimes we can't run server on
the port. possibley due to a race with another process taking it first.

In order to reduce the probability of failure when start redis in
runtest-cluster, we attemp to use another port when find server do not start up.

This fixes the issue described in CVE-2014-5461. At this time we cannot
confirm that the original issue has a real impact on Redis, but it is
included as an extra safety measure.

In order to keep the redismodule.h self-contained but still usable with
gcc v10 and later, annotate each API function tentative definition with
the __common__ attribute. This avoids the 'multiple definition' errors
modules will otherwise see for all API functions at link time.
Further details at gcc.gnu.org/gcc-10/porting_to.html
Turn the existing __attribute__ ((unused)), ((__common__)) and ((print))
annotations into conditional macros for any compilers not accepting this
syntax. These macros only expand to API annotations under gcc.
Provide a pre- and post- macro for every API function, so that they can
be defined differently by the file that includes redismodule.h.
Removing REDISMODULE_API_FUNC in the interest of keeping the function
declarations readable.

Add Linux kernel OOM killer control option.
This adds the ability to control the Linux OOM killer oom_score_adj
parameter for all Redis processes, depending on the process role (i.e.
master, replica, background child).
A oom-score-adj global boolean flag control this feature. In addition,
specific values can be configured using oom-score-adj-values if
additional tuning is required.

Added RedisModule_HoldString that either returns a

in case its not possible to get a shallow copy.

(cherry picked from commit 73198c50194cbf0254afd4cc5245f9274a538d13)
fe8d6fe74 (released in 6.0.6) has a side effect, when processCommand
rejects a command with pre-made shared object error string, it trims the
newlines from the end of the string. if that string is later used with
addReply, the newline will be missing, breaking the protocol, and
leaving the client hung.
It seems that the only scenario which this happens is when replying with
-LOADING to some command, and later using that reply from the CONFIG
SET command (still during loading). this will result in hung client.
Refactoring the code in order to avoid trimming these newlines from
shared string objects, and do the newline trimming only in other cases
where it's needed.

If the server gets MULTI command followed by only read
commands, and right before it gets the EXEC it reaches OOM,
the client will get OOM response.
So, from now on, it will get OOM response only if there was
at least one command that was tagged with `use-memory` flag

Otherwise, it is treated as a single allocation and freed synchronously. The following logic is used for estimating the effort in constant-ish time complexity:
1. Check the number of nodes.
1. Add an allocation for each consumer group registered inside the stream.
1. Check the number of PELs in the first CG, and then add this count times the number of CGs.
1. Check the number of consumers in the first CG, and then add this count times the number of CGs.

When calling to LPOS command when RANK is higher than matches,
the return value is non valid response. For example:
```
LPUSH l a
:1
LPOS l b RANK 5 COUNT 10
*-4
```
It may break client-side parser.
Now, we count how many replies were replied in the array.
```
LPUSH l a
:1
LPOS l b RANK 5 COUNT 10
*0
```

After fork, the child process(redis-aof-rewrite) will get the fd opened
by the parent process(redis), when redis killed by kill -9, it will not
graceful exit(call prepareForShutdown()), so redis-aof-rewrite thread may still
alive, the fd(lock) will still be held by redis-aof-rewrite thread, and
redis restart will fail to get lock, means fail to start.
This issue was causing failures in the cluster tests in github actions.

fe8d6fe749 added rejectCommand which takes an robj reply and passes it
through addReplyErrorSafe to addReplyErrorLength.
The robj contains newline at it's end, but addReplyErrorSafe converts it
to spaces, and passes it to addReplyErrorLength which adds the protocol
newlines.
The result was that most error replies (like OOM) had extra two trailing
spaces in them.

Avoid re-configuring (and validating) SSL/TLS configuration on `CONFIG
SET` when TLS is not actively enabled for incoming connections, cluster
bus or replication.
This fixes failures when tests run without `--tls` on binaries that were
built with TLS support.
An additional benefit is that it's now possible to perform a multi-step
configuration process while TLS is disabled. The new configuration will
be verified and applied only when TLS is effectively enabled.
