RBASIC_CLASS(obj) macro which returns a class of `obj'.
This change is a part of RGENGC branch [ruby-trunk - Feature #8339].
* object.c: add new function rb_obj_reveal().
This function reveal interal (hidden) object by rb_obj_hide().
Note that do not change class before and after hiding.
Only permitted example is:
klass = RBASIC_CLASS(obj);
rb_obj_hide(obj);
....
rb_obj_reveal(obj, klass);
TODO: API design. rb_obj_reveal() should be replaced with others.
TODO: modify constified variables using cast may be harmful for
compiler's analysis and optimizaton.
Any idea to prohibt inserting RBasic::klass directly?
If rename RBasic::klass and force to use RBASIC_CLASS(obj),
then all codes such as `RBASIC(obj)->klass' will be
compilation error. Is it acceptable? (We have similar
experience at Ruby 1.9,
for example "RARRAY(ary)->ptr" to "RARRAY_PTR(ary)".
* internal.h: add some macros.
* RBASIC_CLEAR_CLASS(obj) clear RBasic::klass to make it internal
object.
* RBASIC_SET_CLASS(obj, cls) set RBasic::klass.
* RBASIC_SET_CLASS_RAW(obj, cls) same as RBASIC_SET_CLASS
without write barrier (planned).
* RCLASS_SET_SUPER(a, b) set super class of a.
* array.c, class.c, compile.c, encoding.c, enum.c, error.c, eval.c,
file.c, gc.c, hash.c, io.c, iseq.c, marshal.c, object.c,
parse.y, proc.c, process.c, random.c, ruby.c, sprintf.c,
string.c, thread.c, transcode.c, vm.c, vm_eval.c, win32/file.c:
Use above macros and functions to access RBasic::klass.
* ext/coverage/coverage.c, ext/readline/readline.c,
ext/socket/ancdata.c, ext/socket/init.c,
* ext/zlib/zlib.c: ditto.

* io.c (rb_io_ext_int_to_encs, parse_mode_enc): bom-prefixed name is
not a real encoding name, just a fallback. so the proper conversion
should take place even if if the internal encoding is equal to the
bom-prefixed name, unless actual encoding is equal to the internal
encoding. [ruby-core:54563] [Bug #8323]

found. [ruby-core:54569]

subclasses that include WaitReadable or WaitWritable rather than
extending them into the exception object each time.
* error.c: Capture EGAIN, EWOULDBLOCK, EINPROGRESS exceptions and
export them for use in WaitReadable/Writable exceptions.
* io.c: Create versions of EAGAIN, EWOULDBLOCK, EINPROGRESS that
include WaitReadable and WaitWritable. Add rb_readwrite_sys_fail
for nonblocking failures using those exceptions. Use that
function in io_getpartial and io_write_nonblock instead of
rb_mod_sys_fail
* ext/openssl/ossl_ssl.c: Add new SSLError subclasses that include
WaitReadable and WaitWritable. Use those classes for
write_would_block and read_would_block instead of rb_mod_sys_fail.
* ext/socket/ancdata.c: Use rb_readwrite_sys_fail instead of
rb_mod_sys_fail in bsock_sendmsg_internal and
bsock_recvmsg_internal.
* ext/socket/init.c: Use rb_readwrite_sys_fail instead of
rb_mod_sys_fail in rsock_s_recvfrom_nonblock and
rsock_s_connect_nonblock.
* ext/socket/socket.c: Use rb_readwrite_sys_fail instead of
rb_mod_sys_fail in sock_connect_nonblock.
* include/ruby/ruby.h: Export rb_readwrite_sys_fail for use instead
of rb_mod_sys_fail. Introduce new constants RB_IO_WAIT_READABLE and
RB_IO_WAIT_WRITABLE for first arg to rb_readwrite_sys_fail.
