Rework the engine's internal recursion limit (#2969)
This patch unifies the recursion limit checking for RegExp, function call and JSON as well.
Until now the limit was only a counter which was increased/decreased at certain points.
This counter has been substituted with a numeric limit which allows to restrict the stack usage.

This patch fixes #2963 and resolves the closed #2258 issue.
