Somebody may pass 1030 (the value of F_DUPFD_CLOEXEC) to IO#fcntl
because they copied code from somewhere else. Ensure we know
about FDs created that way.
* io.c (do_fcntl): update max FD for F_DUPFD_CLOEXEC, too

poll(fds, n, 0) mean no timeout and immediately return. If you want to
wait something, you need to use -1 instead.

These methods are useful for safe/concurrent file I/O in
multi-thread/process environments and also fairly standard
nowadays especially in systems supporting pthreads.
Based on patches by Avseyev <sergey.avseyev@gmail.com> at
[ruby-core:79290]. [Feature #4532]
* configure.in: check for pwrite(2). pread() is already used
internally for IO.copy_stream.
* io.c: implement wrappers for pread(2) and pwrite(2) and expose
them in IO.

* io.c: [DOC] various improvements for docs of IO, ARGF, and Kernel:
fix indent to ensure correct code block detection; sync "outbuf"
paragraph for {IO,ARGF}#read, {IO,ARGF}#readpartial, and IO#sysread;
fix formatting of call-seq's; improve Kernel#open example to use nil?;

* IO.{write,read}: fix errors (:open_args is not an array of

* IO#sync=: remove unnecessary "produces no output".

Using rb_ensure pessimizes the common case and makes the code
more difficult to read and follow. If we hit an exceptions
during write, just let the GC handle cleanup as the exception
is already bad for garbage.
* io.c (io_fwrite): call rb_str_tmp_frozen{acquire,release} directly
(rb_io_syswrite): ditto
(fwrite_do, fwrite_end, swrite_do, swrite_end): remove

As with IO#write, IO#syswrite also generates garbage which can
be harmful in hand-coded read-write loops.

Introduce rb_str_tmp_frozen_acquire and rb_str_tmp_frozen_release
to manage a hidden, frozen string. Reuse one bit of the embed
length for shared strings as STR_IS_SHARED_M to indicate a string
has been shared multiple times. In the common case, the string
is only shared once so the object slot can be reclaimed immediately.

This allows Warning.warn to filter/process warning messages
generated by Kernel#warn. Currently, Warning.warn can only handle
messages generated by the rb_warn/rb_warning C functions.
The Kernel#warn API is different than the Warning.warn API, this
tries to get similar behavior, but there are probably corner cases
where the behavior is different.
This makes str_end_with_asciichar in io.c no longer static so it
can be called from error.c.
