new nonterminal for storing lists of separator tokens in the parser
* separator-list.h: New file.
* libinterp/parse-tree/module.mk: Update.
* parse.h, oct-parse.yy (sep_list_type): New nonterminal type.
(sep_no_nl, opt_sep_no_nl, nl, opt_nl, sep, opt_sep): Declare as
sep_list_type instead of punct_type. Update rules to create separator
list objects instead of returning characters. In rules that use them,
delete as yet unsaved separator_list objects.
(punct_type): Delete now unused nonterminal type.
(base_parser::set_stmt_print_flag, base_parser::append_statement_list):
New overloads that accept separator token and separator_list objects.
(base_parser::append_function_def_list): Accept separator_list instead
of char.
(base_parser::make_try_command): Update to use separator list instead
of character.
