* Fix broken protocol when redis can't persist to RDB (general commands, not
modules), excessive newline. regression of #10372 (7.0 RC3)
* Fix broken protocol when Redis can't persist to AOF (modules and
scripts), missing newline.
* Fix bug in OOM check of EVAL scripts called from RM_Call.
set the cached OOM state for scripts before executing module commands too,
so that it can serve scripts that are executed by modules.
i.e. in the past EVAL executed by RM_Call could have either falsely
fail or falsely succeeded because of a wrong cached OOM state flag.
* Fix bugs with RM_Yield:
1. SHUTDOWN should only accept the NOSAVE mode
2. Avoid eviction during yield command processing.
3. Avoid processing master client commands while yielding from another client
* Add new two more checks to RM_Call script mode.
1. READONLY You can't write against a read only replica
2. MASTERDOWN Link with MASTER is down and `replica-serve-stale-data` is set to `no`
* Add new RM_Call flag to let redis automatically refuse `deny-oom` commands
while over the memory limit.
* Add tests to cover various errors from Scripts, Modules, Modules
calling scripts, and Modules calling commands in script mode.
Add tests:
* Looks like the MISCONF error was completely uncovered by the tests,
add tests for it, including from scripts, and modules
* Add tests for NOREPLICAS from scripts
* Add tests for the various errors in module RM_Call, including RM_Call that
calls EVAL, and RM_call in "eval mode". that includes:
NOREPLICAS, READONLY, MASTERDOWN, MISCONF
