ktsj 243842f68a Avoid usage of the dummy empty BEGIN node 
Use NODE_SPECIAL_NO_NAME_REST instead.

yui-knk b8b503d657 Add symbol to the result of `RubyVM::AbstractSyntaxTree#children`. 
Add symbol to the result to make pattern match easily.

For example:

(1) NODE_MASGN * NODE_SPECIAL_NO_NAME_REST

```
$ ./miniruby -e 'p RubyVM::AbstractSyntaxTree.parse("a, * = b").children[-1].children'
[#<RubyVM::AbstractSyntaxTree::Node:VCALL@1:7-1:8>, #<RubyVM::AbstractSyntaxTree::Node:ARRAY@1:0-1:1>, :NODE_SPECIAL_NO_NAME_REST]
```

(2) NODE_POSTARG * NODE_SPECIAL_NO_NAME_REST

```
$ ./miniruby -e 'p RubyVM::AbstractSyntaxTree.parse("a, *, _ = b").children[-1].children[-1].children'
[:NODE_SPECIAL_NO_NAME_REST, #<RubyVM::AbstractSyntaxTree::Node:ARRAY@1:6-1:7>]
```

(3) NODE_LASGN * NODE_SPECIAL_REQUIRED_KEYWORD

```
$ ./miniruby -e 'p RubyVM::AbstractSyntaxTree.parse("def a(k:) end").children[-1].children[-1].children[1].children[7].children[0].children'
[:k, :NODE_SPECIAL_REQUIRED_KEYWORD]
```

yui-knk acc48fce30 ast.c: Change tabs to spaces 
* ast.c: I created a new C source code file with tabs and spaces mixed
  format by mistake. Currently we move to spaces only.
  Surely we agreed not to batch update. But ast.c is a new
  source code. So please forgive me to change the format before
  many changes are committed this file.
  I'm sorry about my mistake.
