Subject: * cont.c: support Fiber.  Check test/ruby/test_fiber.rb for detail.  
 Fiber is known as "Micro Thread", "Coroutine", and other terms.   At this
 time, only Fiber#pass is supported to change context.   I want to know more
 suitable method name/API for Fiber (... do you   know more suitable class
 name instead of Fiber?) as "suspend/resume",   "call", "yield",
 "start/kick/stop/restart", .... * eval.c, eval_intern.h, thread.c,
 yarvcore.c, yarvcore.h: ditto.
