Backport #8891: Mutex#unlock が trap handlerから呼べない

[ruby-dev: 46644] で Mutex#try_lock は trapから呼べるように仕様変えたと言っているのに
unlockが依然として例外あげるので実質そうなっていませんでした。

確認不足、申し訳ない。直します。

• thread.c (rb_mutex_unlock): Mutex#unlock no longer raise
  an exception even if uses on trap. [Bug #8891]

• Backport changed from 1.9.3: UNKNOWN, 2.0.0: UNKNOWN to 1.9.3: DONTNEED, 2.0.0: REQUIRED

トラップハンドラ内で try_lock を許すようにしたのが r37922 (2012-11-28) だと思うので 2.0.0 にも必要ですよね。
