A doubly-linked list for tracking living threads guarantees
constant-time insert/delete performance with no corner cases of a
hash table. I chose this ccan implementation of doubly-linked
lists over the BSD sys/queue.h implementation since:
1) insertion and removal are both branchless
2) locality is improved if a struct may be a member of multiple lists
(0002 patch in Feature 9632 will introduce a secondary list
for waiting FDs)
This also increases cache locality during iteration: improving
performance in a new IO#close benchmark with many sleeping threads
while still scanning the same number of threads.

[ruby-core:61871][Feature 9632 (part 1)]
Apologies for the size of this commit, but I think a good
doubly-linked list will be useful for future features, too.
This may be used to add ordering to a container_of-based hash
table to preserve compatibility if required (e.g. feature 9614).

Pre-allocate MAX_POSTPONED_JOB (1024) sized buffer

If rb_postponed_job_register() cause overflow, simply it

https://github.com/ruby/ruby/pull/373

* RUBY_INTERNAL_EVENT_NEWOBJ: object created.
* RUBY_INTERNAL_EVENT_FREE: object freeed.
* RUBY_INTERNAL_EVENT_GC_START: GC started.
And rename `RUBY_EVENT_SWITCH' to `RUBY_INTERNAL_EVENT_SWITCH'.
Internal events can not invoke any Ruby program because the tracing
timing may be critical (under huge restriction).
These events can be hooked only by C-extensions.
We recommend to use rb_potponed_job_register() API to call Ruby
program safely.
This change is mostly written by Aman Gupta (tmm1).

[Feature #8107]
* include/ruby/debug.h, vm_trace.c: added two new APIs.
* rb_tracearg_event_flag() returns rb_event_flag_t of this event.
* rb_tracearg_object() returns created/freeed object.

ext/-test-/tracepoint/tracepoint.c,

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).

of IFUNC frame.
When `rb_binding_new_with_cfp()' is called, VM finds out the first
normal (has iseq) frame and create a binding object of this frame
and create Env objects. `ep's of related frames are updated
(`ep's point Env object managed spaces).
However, `ep' of skipped IFUNC frame was not updated and
old invalid `ep' was remained. It causes serious problems.
To solve this issue, permit IFUNC to create binding.
(Maybe there is no problem on it)
[ruby-dev:46908] [ruby-trunk - Bug #7774]
* test/ruby/test_settracefunc.rb: add a test.
* vm.c (rb_vm_get_binding_creatable_next_cfp), vm_core.h: added.
