Instead of `_foo`. This makes it useful to do word boundary search of
the editor.

Currently, parse.y actions are hard to read and write because the code
has double meaning (for core parser and for ripper). I think that, if
it is easy to write ripper's code shortly and simply, the double meaning
trick is not needed.
For the sake, this change adds a simple DSL for ripper's code. For
example, in parse.y, we can write:
/*% ripper: stmts_add(stmts_new, void_stmt) %*/
instead of:
$$ = dispatch2(stmts_add, dispatch0(stmts_new),
dispatch0(void_stmt));

keyword argument, for core and ripper.

NODE_FOR was used both for "for"-statement itself and for
multi-assignment of for-statement (for x, y, in...end).
This change separates the two purposes, NODE_FOR for the former, and
newly introduced NODE_FOR_MASGN for the latter.

There were four cases that uses new_command_qcall and then
method_add_block. This change factors out the four rules.

r12117.

The current parse.y won't compile with yacc since it depends on many
bison's extensions. Also, configure.ac does not have a check for yacc,
so the macro OLD_YACC is no longer used.

In parse.y many functions were suffixed "_gen" and had companion macros
to pass struct parser_params implicitly, which made parse.c bigger and
more obscure.
This change expands and removes almost all "*_gen" macros. This
requires explicit passing of struct parser_params, i.e., we need to
write "foo(p, ..)" instead of "foo(..)". However, it is just extra
three letters. I believe that this is easier to understand.

For example, `lex_strterm` is expanded to `p->lex.strterm`.
I believe that this expansion make the code straightforward.
They look not so annoying because "parser" was renamed to "p".

Because I want to use the name "p" for struct parser_params through
parse.c. This change renames "p" to "ptr", "paren", etc. depending upon
the context.

cmdarg_stack became inconsistent state due to look-ahead, and LEXPOP
hack smoothed over the inconsistency.
This commit fixes the inconsisitent state itself, and removes LEXPOP
hack.
