fb0783c710 Handle output buffer limits for Module blocked clients (#8141)
Module blocked clients cache the response in a temporary client,
the reply list in this client would be affected by the recent fix
in #7202, but when the reply is later copied into the real client,
it would have bypassed all the checks for output buffer limit, which
would have resulted in both: responding with a partial response to
the client, and also not disconnecting it at all.

dbf3902481 Add Module API for version and compatibility checks (#7865)
* 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
