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.

Running with TESTS=--no-retry, I sometimes get short reads
leading to failures due to the use of IO#readpartial instead of
IO#gets.

Apparently my tty can't keep up when I run test-all with
TESTS='-v --no-retry'

I'm not entirely sure why, but SIGTTOU pauses the test
when running test-all in parallel.

This should make portability problems more apparent when we try
using ppoll with rb_wait_for_single_fd on FreeBSD or other
non-Linux platforms.

it if it is unprintable.

select(2) in AIX returns "readable" for the write-side fd
of a pipe, so it is not possible to use a pipe to test
the read-write timeout of IO#wait on AIX.
