The `sq_setparamscheck` function, instead of accepting just one `SQInteger nparamscheck` parameter, now accepts `SQInteger nparamscheckmin` and `SQInteger nparamscheckmax`. Those define the minimum/maximum for the parameters number check policy. Setting any of them to 0 or negative disables the respective check. This enables support for optional parameters.

The
sq_setparamscheckfunction, instead of accepting just theSQInteger nparamscheckparameter, now accepts bothSQInteger nparamscheckminandSQInteger nparamscheckmax.Those define the minimum/maximum for the parameters number check policy. Setting any of them to 0 or negative disables the respective check.
I believe this change makes the parameter check way less restrictive and suitable for more use-cases. For example, it enables support for default arguments.
NOTE: This change makes changes to the API functions
sq_setparamscheckandsq_getclosureinfo. I am not sure how Squirrel handles such changes (deprecation mechanic?). Because of this, I understand that this change might not be suitable for upstream.
