Fix build mruby for NetBSD

fix type of mrb_exc_new()'s len parameter

mrb_str_new() takes size_t, so should mrb_exc_new().

remove SET_PROC_VALUE() macro

It isn't used anymore since the #2791 merge. It's also unlikely to be
needed again as it wasn't before (its usage was unnecessary).

Use `mrb_funcall` instead of `mrb_load_string` in test driver.

let the C compiler validate the identifier

remove mrb_define_method_vm() function

Update Coopyright Information to year 2015

Some C compilers may allow other characters in identifiers such as $.
They may also implement C99's extended identifiers (\u30EB\u30D3\u30FC,
ルビー).

It isn't needed as it's very similar to mrb_define_method_raw() and also
there's only one place where mrb_proc_ptr() actually has to be called.

Inspired by @furunkel's method cache patch (#2764).

Related to #2760.

Reenable mrb_dump_irep under DISABLE_STDIO.

remove unused token declarations

Avoid unnecessary stores and reloads

Remove INSTALL and improve README instead

fix splat without assignment

The parser generates NODE_NIL for tSTAR without argument in masgns. The
codegen didn't handle that.

define YYDEBUG macro conditionally

Defining static version of frexpl also fro MIPS platforms.

On MIPS/linaro, libm.so lacks frexpl() as CygWin does.

The YYDEBUG macro enables parser debugging which
unnecessarily increases the executable size (9 to 10 KB).
Now it only will be defined when PARSER_DEBUG is too.
