(Vbacktrace_on_warning, Vbeep_on_error, Vdebug_on_caught, Vdebug_on_error, Vdebug_on_warning, Vlast_error_id, Vlast_error_message, Vlast_error_stack, Vlast_warning_id, Vlast_warning_message, Vquiet_warning, Vverbose_warning, buffer_error_messages, discard_error_messages, discard_warning_messages, in_try_catch, warning_options): Move global and file-scope static variables inside error_system class. Change all uses. * interpreter.h, interpreter.cc (m_error_system): New member variable. (get_error_system): New function. * interpreter-private.h, interpreter-private.cc (__get_error_system__): New function.
