move file-scope static autoload map variable and functions to evaluator * interpreter.h, interpreter.cc (interpreter::autoloaded_functions): New function. * pt-eval.h, pt-eval.cc (tree_evaluator::m_autoload_map): New member variable, replaces static file-scope variable in oct-parse.yy. (tree_evaluator::get_autoload_map, tree_evaluator::lookup_autoload, tree_evaluator::autoloaded_functions, tree_evaluator::add_autoload, tree_evaluator::reverse_lookup_autoload, tree_evaluator::remove_autoload): New functions, replace similar global and file-scope static functions in oct-parse.yy. Change all uses. (check_autoload_file): New function.
