Previous code would have added default redis save parameters
to the config file on rewrite, which would have been silently ignored
when the config file is loaded.
The new code avoids adding this, and also actively removes these lines
If added by a previous config rewrite.

This wrong behavior was backed by a test, and also documentation, and dates back to 2010.
But it makes no sense to anyone involved so it was decided to change that.
Note that 3b031b1 (invalidate watch on expire on access) was released in 6.0 RC2
and 62a3ec8 released in in 6.0.0 GA (invalidate watch when key is evicted).
both of which do similar changes.

In some cases one command added a very big bulk of memory, and this
would be "resolved" by the eviction before the next command.
Seeing an unexplained mass eviction we would wish to
know the highest momentary usage too.
Tracking it in call() and beforeSleep() adds some hooks in AOF and RDB
loading.
The fix in clientsCronTrackExpansiveClients is related to #7874

This is a compatibility issue with redis 5.0 that was introduced by ACL.
Before this commit, setting requirepass to an empty string will result
in a server that needs an empty AUTH, unlike redis 5.0 which would
accept connections without an AUTH.

If we fail or stop to rewrite aof, we need to remove temporary aof.
We also remove temporary rdb when replicas abort to receive rdb.
But currently we delete them in main thread, to avoid blocking,
we should use bg_unlink to remove them in a background thread.
Btw, we have already used this way to removed child process temporary rdb.

* Introduce a new API's: RM_GetContextFlagsAll, and
RM_GetKeyspaceNotificationFlagsAll that will return the
full flags mask of each feature. The module writer can
check base on this value if the Flags he needs are
supported or not.
* For each flag, introduce a new value on redismodule.h,
this value represents the LAST value and should be there
as a reminder to update it when a new value is added,
also it will be used in the code to calculate the full
flags mask (assuming flags are incrementally increasing).
In addition, stated that the module writer should not use
the LAST flag directly and he should use the GetFlagAll API's.
* Introduce a new API: RM_IsSubEventSupported, that returns for a given
event and subevent, whether or not the subevent supported.
* Introduce a new macro RMAPI_FUNC_SUPPORTED(func) that returns whether
or not a function API is supported by comparing it to NULL.
* Introduce a new API: int RM_GetServerVersion();, that will return the
current Redis version in the format 0x00MMmmpp; e.g. 0x00060008;
* Changed unstable version from 999.999.999 to 255.255.255

The main motivation here is to provide a way for modules to create a
single, global context that can be used for logging.
Currently, it is possible to obtain a thread-safe context that is not
attached to any blocked client by using `RM_GetThreadSafeContext`.
However, the attached context is not linked to the module identity so
log messages produced are not tagged with the module name.
Ideally we'd fix this in `RM_GetThreadSafeContext` itself but as it
doesn't accept the current context as an argument there's no way to do
that in a backwards compatible manner.

I suppose that it was overlooked, since till recently none of the blocked commands were readonly.
other changes:
- add test for the above.
- add better support for additional (and deferring) clients for
cluster tests
- improve a test which left the client in MULTI state.

track and report memory used by clients argv.
this is very usaful in case clients started sending a command and didn't
complete it. in which case the first args of the command are already
trimmed from the query buffer.
in an effort to avoid cache misses and overheads while keeping track of
these, i avoid calling sdsZmallocSize and instead use the sdslen /
bulk-len which can at least give some insight into the problem.
This memory is now added to the total clients memory usage, as well as
the client list.
