As it is just a hint the kernel is free to ignore,
IO#advise already succeeds when posix_fadvise is not
available build time at all. Following that, if posix_fadvise
was available at build time but not implemented in the running
kernel, we should also ignore it.

Manpages for opendir(2), socket(2), and socketpair(3posix)
describe ENOMEM as a possible error for each of these;
handle it consistently with our existing wrappers for
open(2)/pipe(2) etc...

This simplifies callers and makes error handling more consistent
between our pipe, open, fdopen, and dup wrappers.
This adds missing ENOMEM handling as documented in the open(2),
pipe(2freebsd), and fdopen(3posix) manpages on my system.
We also avoid repeatedly accessing `errno` which is implemented
in TLS on GNU/Linux systems and more expensive to read than a
local variable.
We may export this in internal.h for ext/socket/* and dir.c, too.

rb_scan_args and hash lookups for kwargs in the C API are clumsy and
slow. Instead of improving the C API for performance, use Ruby
instead :)
Implement IO#read_nonblock and IO#write_nonblock in prelude.rb
to avoid argument parsing via rb_scan_args and hash lookups.
This speeds up IO#write_nonblock and IO#read_nonblock benchmarks
in both cases, including the original non-idiomatic case where
the `exception: false' hash is pre-allocated to avoid GC pressure.
Now, writing the kwargs in natural, idiomatic Ruby is fastest.
I've added the noex2 benchmark to show this.

poll and ppoll have a superior API which doesn't require the
kernel to scan a potentially large bitmap to find a high-numbered
FD [ruby-core:35572]. So favor using poll in case IO.copy_stream
encounters a non-blocking FD.
We cannot reliably use poll on most OSes, because file types (e.g.
FIFOs) which work with select may not work with poll. Fortunately,
Linux uses a common notification mechanism between all
select/poll/epoll variants, so all file types are equally supported
between the notification mechanisms.
Verified by watching strace on the following scripts:
*** maygvl_copy_stream_wait_read ***
require 'io/nonblock'
r, w = IO.pipe
r.nonblock = true
IO.copy_stream(r, "/dev/null")
*** nogvl_copy_stream_wait_write ***

r, w = IO.pipe
w.nonblock = true
IO.copy_stream("/dev/zero", w)
