This affects test/ruby/test_process.rb (test_execopt_env_path).
Since MJIT uses vfork+execve in a separate thread, there can be
small window in-between vfork and execve where tmp_script.cmd is
held open by the vforked child. vfork only pauses the MJIT
thread, not any Ruby Threads, so our call to Process.spawn will
hit ETXTBUSY in that window unless we fork.
main thread | MJIT thread
----------------------------------------------------
fd = open(tmp) | |
| vfork for CC | CC running
write | | ---------------
fchmod | | sees "fd" here
close(fd) | |
Process.spawn called | |
vfork (spawn)| (new process) | |
| execve => TXTBUSY | |
| | | execve (FD_CLOEXEC on fd)
| | vfork returns |
Holding the waitpid_lock whenever we intend to spawn a process
prevents the MJIT thread from spawning a process while we are
spawning in Ruby-land.

There seems to be a compatibility problems with Rails +
Rack::Deflater; so we revert this incompatibility.
This effectively reverts r65922; but keeps the bugfixes to
better support non-blocking sockets and pipes for future use.

This option enables a hook only at specified target_line.
target_line should be combination with target and :line event.

* vm_trace.c (rb_tracepoint_enable_for_target): support targetting
TracePoint. [Feature #15289]
Tragetting TracePoint is only enabled on specified method, proc
and so on, example: `tp.enable(target: code)`.
`code` should be consisted of InstructionSeuqnece (iseq)
(RubyVM::InstructionSeuqnece.of(code) should not return nil)
If code is a tree of iseq, TracePoint is enabled on all of
iseqs in a tree.
Enabled tragetting TracePoints can not enabled again with
and without target.
* vm_core.h (rb_iseq_t): introduce `rb_iseq_t::local_hooks`
to store local hooks.
`rb_iseq_t::aux::trace_events` is renamed to
`global_trace_events` to contrast with `local_hooks`.
* vm_core.h (rb_hook_list_t): add `rb_hook_list_t::running`
to represent how many Threads/Fibers are used this list.
If this field is 0, nobody using this hooks and we can
delete it.
This is why we can remove code from cont.c.
* vm_core.h (rb_vm_t): because of above change, we can eliminate
`rb_vm_t::trace_running` field.
Also renamed from `rb_vm_t::event_hooks` to `global_hooks`.
* vm_core.h, vm.c (ruby_vm_event_enabled_global_flags): renamed
from `ruby_vm_event_enabled_flags.
* vm_core.h, vm.c (ruby_vm_event_local_num): added to count
enabled targetting TracePoints.
* vm_core.h, vm_trace.c (rb_exec_event_hooks): accepts
hook list.
* vm_core.h (rb_vm_global_hooks): added for convinience.
* method.h (rb_method_bmethod_t): added to maintain Proc
and `rb_hook_list_t` for bmethod (defined by define_method).
* prelude.rb (TracePoint#enable): extracet a keyword parameter
(because it is easy than writing in C).
It calls `TracePoint#__enable` internal method written in C.
* vm_insnhelper.c (vm_trace): check also iseq->local_hooks.
* vm.c (invoke_bmethod): check def->body.bmethod.hooks.
* vm.c (hook_before_rewind): check iseq->local_hooks
and def->body.bmethod.hooks before rewind by exception.

Object#=~ always returns nil. This behavior is not only unuseful but
also troublesome because it may hide a type error.
This change deprecates Object#=~. For compatibility, NilClass#=~ is
newly introduced. [Feature #15231]

RDoc::Options#@exclude is initialized as an empty array.
Then, #finish converts it to a regexp or nil and reassign it to @exclude.
Some methods of RDoc assumes that #finish has been already called.
So, this change forces to assign nil to @exclude.
This type confusion was found during work for removal of `Object#=~`.

single enumerator.

e = (1..3).chain([4, 5])

Since non-blocking I/O is the default after [Bug #14968],
we will hit it more often and cause more acquisition/release

This also lets us avoid touching the temporal string locking
as much and lets us clean up some test changes made for
