Recent monitor.rb has performance problem because of interrupt
handlers. 'Monitor#synchronize' is frequently used primitive
so the performance of this method is important.
This patch rewrite 'monitor.rb' with 'monitor.so' (C-extension)
and make it faster. See [Feature #16255] for details.
Monitor class objects are normal object which include MonitorMixin.
This patch introduce a Monitor class which is implemented on C
and MonitorMixin uses Monitor object as re-entrant (recursive)
Mutex. This technique improve performance because we don't need
to care atomicity and we don't need accesses to instance variables
any more on Monitor class.
If an exception is raised from another thread for example Timeout
and this thread is just after `mon_exit`'s `@mon_owner = nil`,
the exception breaks the state of MonitorMixin. To prevent that situation,
it need to block interruption in mon_enter and mon_exit.
and allow to initialize again when obj.dup.

Because mon_initialized may be used to re-initialize copied objects intentionally.
mon_initialize_spec.rb fails:
1)
MonitorMixin#mon_initialize can be called in initialize_copy to get a new Mutex and used with synchronize ERROR

When you change this to true, you may need to add more tests.

private methods as well (previous 1.9 send behavior).

support NodeWrap and ParseTree.
* rubysig.h (CHECK_INTS): prevent signal handler to run during
critical section. [ruby-core:04039]

tradition.
