* include/ruby/debug.h, vm_trace.c: add rb_postponed_job API.
Postponed jobs are registered with this API. Registered jobs are invoked at `ruby-running-safe-point' as soon as possible. This timing is completely same as finalizer timing. There are two APIs: * rb_postponed_job_register(flags, func, data): register a postponed job with data. flags are reserved. * rb_postponed_job_register_one(flags, func, data): same as `rb_postponed_job_register', but only one `func' job is registered (skip if `func' is already registered). This change is mostly written by Aman Gupta (tmm1). https://bugs.ruby-lang.org/issues/8107#note-15 [Feature #8107] * gc.c: use postponed job API for finalizer. * common.mk: add dependency from vm_trace.c to debug.h. * ext/-test-/postponed_job/extconf.rb, postponed_job.c, test/-ext-/postponed_job/test_postponed_job.rb: add a test. * thread.c: implement postponed API. * vm_core.h: ditto. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@40940 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
