I'm not entirely sure why, but test_set_winsize_console gets stuck on
Solaris (and if I recall, macOS). I found a hack for FreeBSD, so I want
to give it a try on Solaris too.
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.
[ruby-core:89950] [Bug #14968]

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.

* test/io/console/test_io_console.rb: flush to ensure the second
data is sent.

* test/io/console/test_io_console.rb (test_set_winsize_console):
split from test_get_winsize_console and enable the case when
attached to a console already

Not so good test, but it would be better than nothing, I guess...

* test/io/console/test_io_console.rb (test_winsize): on old CentOS5
window size seems unable to be set across a pty.

* ext/io/console/console.c (console_key_pressed_p): raise the same
exception, "unknown virtual key code", for names with nul chars.
though console_win32_vk() considers the length and can deal with
nul chars, rb_sprintf() raised at PRIsVALUE previously, so quote
it if it is unprintable.

* test/io/console/test_io_console.rb: move conditions for method
definitions before the bodies.

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.
