Add check_stack_depth() to Jsonb_to_SV, SV_to_JsonbValue, PLyObject_FromJsonbContainer, and PLyObject_ToJsonbValue. Without this, deeply nested JSONB values can crash the backend with SIGSEGV instead of raising a proper error. Also add CHECK_FOR_INTERRUPTS() to the while loop in SV_to_JsonbValue that dereferences chains of Perl references, so that a circular reference (e.g. $x = \$x) can be cancelled by the user instead of spinning indefinitely. (We looked at detecting such circular references, but it seems more trouble than it's worth.)
