* io.c: [DOC] improve docs for IO
* IO.{write,read}: fix errors (:open_args is not an array of
strings, it might include a perm or options hash argument;
IO.write has no length argument, drop corresponding statement),
improve formatting, call-seq, grammar.
* 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.

This was made obsolete by r4190 back in July 2003. Furthermore,
this existed less than 3 months as it was only introduced in
r3782.
So with absolutely no references to rb_deferr, I doubt any vim
plugin would care anymore.
