* gc.c : remove gc_clear_mark_on_sweep_slots() and use rest_sweep() instead of it, because some dead objects might be marked in next the mark phase by false pointers. [ruby-core:42672] git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/branches/ruby_1_9_3@34737 b2dd03c8-39d4-4d8f-98ff-823fe69b080e

* cont.c (rb_fiber_reset_root_local_storage): add a new function to restore rb_thread_t::local_storage. * cont.c (rb_obj_is_fiber): add a new function to tell finalizer to prevent fibers from destroy. * gc.c (rb_objspace_call_finalizer): don't sweep fibers at finalizing objspace. * internal.h (rb_fiber_reset_root_local_storage, rb_obj_is_fiber): add prototypes. * vm.c (ruby_vm_destruct): reset main thread's local_storage before free main thread. rb_thread_t::local_storage is replaced by fiber's local storage when forked from fiber, and it should be already freed when the fiber was destroyed. * test/ruby/test_fiber.rb (test_fork_from_fiber): add test for fork from fiber. when the fiber was destroyed.

possible for an object to survive until its surrounding object space is about to be freed. Those objects, if any, remains not leaked for the rest of a process life.
