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.

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.

Backtrace information contains an array consists of location
information for each frames by string.
RubyVM::Backtrace object is lightweight backtrace information,
which contains complete information to generate traditional style
backtrace (an array of strings) with faster generation.
If someone accesses to backtrace information via
Exception#backtrace, then convert a RubyVM::Backtrace object to
traditonal style backtrace.
This change causes incompatibility on marshal dumpped binary
of Exception. If you have any trouble on it, please tell us
before Ruby 2.0 release.
Note that RubyVM::Backtrace object should not expose Ruby level.
* error.c, eval.c, vm_eval.c: ditto.
* internal.h: ditto.
* eval_error.c: fix to skip "set_backtrace" method invocation in
creating an exception object if it call a normal set_backtrace
method (defined by core).
* test/ruby/test_settracefunc.rb: fix for above change.
* vm_method.c (rb_method_defined_by): added. This function
checks that the given object responds with the given method
by the given cfunc.
* benchmark/bm_vm2_raise1.rb, benchmark/bm_vm2_raise2.rb:
add to measure exception creation speed. raise1 create
exception objects from shallow stack frame. raise2 create
exception objects from deep stack frame.
