* vm_trace.c, vm_core.h: simplify tracing mechanism.
(1) add rb_hook_list_t data structure which includes hooks, events (flag) and `need_clean' flag. If the last flag is true, then clean the hooks list. In other words, deleted hooks are contained by `hooks'. Cleanup process should run before traversing the list. (2) Change check mechanism See EXEC_EVENT_HOOK() in vm_core.h. (3) Add `raw' hooks APIs Normal hooks are guarded from exception by rb_protect(). However, this protection is overhead for too simple functions which never cause exceptions. `raw' hooks are executed without protection and faster. Now, we only provide registration APIs. All `raw' hooks are kicked under protection (same as normal hooks). * include/ruby/ruby.h: remove internal data definition and macros. * internal.h (ruby_suppress_tracing), vm_trace.c: rename ruby_suppress_tracing() to rb_suppress_tracing() and remove unused function parameter. * parse.y: fix to use renamed rb_suppress_tracing(). * thread.c (thread_create_core): no need to set RUBY_VM_VM. * vm.c (mark_event_hooks): move definition to vm_trace.c. * vm.c (ruby_vm_event_flags): add a global variable. This global variable represents all of Threads and VM's event masks (T1#events | T2#events | ... | VM#events). You can check the possibility kick trace func or not with ruby_vm_event_flags. ruby_vm_event_flags is maintained by vm_trace.c. * cont.c (fiber_switch, rb_cont_call): restore tracing status. [Feature #4347] * test/ruby/test_continuation.rb: ditto. git-svn-id: svn+ssh:// b2dd03c8-39d4-4d8f-98ff-823fe69b080e
