* thread.c: fix Mutex to be interruptable lock.

* thread_win32.ci, thread_win32.h, thread_pthread.ci, thread_pthread.h:
  prepare native_cond_*() which are based on pthread_cond_*() spec.
* prelude.rb: fix Mutex#synchronize method.
* vm_core.h, include/ruby/intern.h: change unblock function interface
  (to pass some user data).
* file.c, process.c: ditto.
* benchmark/bm_vm2_mutex.rb: add a benchmark for mutex.
* benchmark/bm_vm3_thread_mutex.rb: add a benchmark for mutex
  with contension.
* benchmark/run.rb: fix to remove ENV['RUBYLIB'] for matzruby.
* test/ruby/test_thread.rb: add a test.
* common.mk: fix benchmark options.
