Terminate the input from a TTY by 2 ^D at the middle of line, like

suppress a false warning by icc.
Heredocs are parsed line-by-line, so we need to keep track of the
temporary encoding of the string. Previously, a heredoc would
only detect mixed encoding errors if they were on the same line,
this changes things so they will be caught on different lines.

This allows cases such as:
```ruby
m ->(a = ->{@1}) {a}
m.call.call(1)
m2 ->(a: ->{@1}) {a}
m2.call.call(2)
```
Previously, this would cause a syntax error.
[Bug#15789]
Because `proc{|| @1}` is a syntax error, the following should
also be syntax errors:
```ruby

```ruby

```
This fixes both cases.

The code fragments that initializes coverage data were scattered into
both parse.y and compile.c. parse.y allocated a coverage data, and
compile.c initialize the data.
To remove this cross-cutting concern, this change moves the allocation
from "coverage" function of parse.y to "rb_iseq_new_top" of iseq.c.
For the sake, parse.y just counts the line number of the original source
code, and the number is passed via rb_ast_body_t.

Now endless range can be created by either a literal `(1..)` or explicit
range creation `Range.new(1, nil)`. [Bug #14845]
This change is intended for "early failure"; for example,
`(1..var).to_a` causes out of memory if `var` is inadvertently nil.

When an empty rule or a mid-rule action is reduced,
`YYLLOC_DEFAULT` is called with the third parameter to be zero.
If we use `RUBY_SET_YYLLOC_OF_NONE` to set their locations,
sometimes the end position of NODE indicates a blank.
For example, `a.b ;` generates `NODE_CALL (line: 1, location: (1,0)-(1,4))*`,
whose end position indicates a blank.
This is because of the following reasons:
* `NODE_CALL` is created when `primary_value call_op operation2 opt_paren_args` is
reduced to `method_call`.
* `opt_paren_args` is `none`.
* `yylex` is called and `lex.pbeg` moves before `none` is reduced, so
the beginning position of `none` does not match with the end position of `operation2`.
To fix locations, use `YYRHSLOC(Rhs, 0)` in `YYLLOC_DEFAULT`
(0 "refers to the symbol just before the reduction").
By this change, the bottom of the location stack would be referenced,
so initialize the bottom with `RUBY_SET_YYLLOC_OF_NONE` in `%initial-action`.

Currently, parser.y includes core parser and Ripper parser obscurity.
In addition, *some* Ripper code uses the result of the core parser,
which make it difficult to separate the two parsers.
I want to simplify this, not by separating the two parsers, but by
making *all* Ripper actions follows the core parser actions.
In other words, all the core parser actions run always even in Ripper,
and after that, Ripper-specific actions run.
For tha sake, in principle, I want to put `/*% ripper: ... %*/` in the
end of actions.
Anyway, it is too dirty to put it within expressions, IMO.

I thought this trick was needed because the result of var_field was
passed to different arguments, as follows:
```
$1 = var_field(p, $1);
$$ = backref_assign_error(p, $1, $1, &@$);
```
Currently the DSL supports that one result is passed to one argument.
However, after the refactoring, I found that `backref_assign_error`
uses only one `$1`.

`foo!(...)` means Ripper event, and `foo(...)` means C function/macro
call. This is for fail-safe; if I forget `!` accidentally, it would
fail to compile, instead of wrongly adding a new Ripper event.

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));

NODE_FOR was used both for "for"-statement itself and for

This change separates the two purposes, NODE_FOR for the former, and
newly introduced NODE_FOR_MASGN for the latter.

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 the name "code_range" is ambiguous with encoding's.
Abbreviations ("crange", and "cr") are also renamed to "loc".

(first_loc to beg_pos, and last_loc to end_pos).

Start position of `@$` is same as start position of `@1`.
And NEW_XXX macros set first_loc.lineno of a passed

"loc" was ambiguous; it might refer both a location and a code range.
This change uses "loc" for a location, and "crange" or "cr" for a code
range.
A location (abbr. loc) is a point in a program and consists of line
number and column number. A code range (abbr. crange and cr) is a range
within a program and consists of a pair of locations which is the first
and the last.

BEGIN {
