All normal Ruby IO methods (IO#read, IO#gets, IO#write, ...) are
all capable of appearing to be "blocking" when presented with a
file description with the O_NONBLOCK flag set; so there is
little risk of incompatibility within Ruby-using programs.
The biggest compatibility risk is when spawning external
programs. As a result, stdin, stdout, and stderr are now always
made blocking before exec-family calls.
This change will make an event-oriented MJIT usable if it is
waiting on pipes on POSIX_like platforms.
It is ALSO necessary to take advantage of (proposed lightweight
concurrency (aka "auto-Fiber") or any similar proposal for
network concurrency: https://bugs.ruby-lang.org/issues/13618
Named-pipe (FIFO) are NOT yet non-blocking by default since
they are rarely-used and may introduce compatibility problems
and extra syscall overhead for a common path.
Please revert this commit if there are problems and if I am afk
since I am afk a lot, lately.

worker. It's very likely to be thread-unsafe and so it's better to avoid
using in MJIT worker to prevent surprises by race condition.

I'm simplifying the interface of ChildRecord as I'm going to complicate
it a little next.
I didn't drop hInput since leaving it would be more natural as its
interface.

Prior to this commit, some of parent process's output was unintentionally
suppressed. We couldn't suppress only child process's output with spawnvp.
Instead of that, this commit uses CreateProcess directly to redirect stdout
and stderr only for child process.
As it's dealing with HANDLE returned from CreateProcess, now waitpid macro
needs to CloseHandle it.
win32/win32.c: Introduce rb_w32_start_process which is designed for MJIT
worker. Other similar functions can't be used since they are using ALLOCV
that may trigger GC, which should be avoided on MJIT worker.

Support nanosec file timestamp on Windows 8 or later.
Original patches are written by kubo (Kubo Takehiro).
Windows 7 and earlier also supports nanosec file timestamp, but it's too
accurate than system time. so, this feature is disabled on such versions.

This patch is based on Takehiro Kubo <kubo@jiubao.org> 's one (change only
the name of wrapper function). Thanks! and sorry to late
