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.

th->base_block is information for (a) parsing, (b) compiling
and (c) setting up the frame to execute the program passed by
`eval' method. For example, (1) parser need to know up-level
variables to detect it is variable or method without paren.
Befor (a), (b) and (c), VM set th->base_block by passed bindng
(or previous frame information). After execute (a), (b) and (c),
VM should clear th->base_block. However, if (a), (b) or (c)
raises an exception, then th->base_block is not cleared.
Problem is that the uncleared value th->balo_block is used for
irrelevant iseq compilation. It causes SEGV or critical error.
I tried to solve this problem: to clear them before exception,
but finally I found out that it is difficult to do it (Ruby
program can be run in many places).
Because of this background, I set th->base_block before
compiling iseq and restore it after compiling.
Basically, th->base_block is dirty hack (similar to global
variable) and this patch is also dirty.
* bootstraptest/test_eval.rb: add a test for above.
* internal.h: remove unused decl.
* iseq.c (rb_iseq_compile_with_option): add base_block parameter.
set th->base_block before compation and restore it after
compilation.
* ruby.c (require_libraries): pass 0 as base_block instead of
setting th->base_block
* tool/compile_prelude.rb (prelude_eval): apply above changes.
* vm.c, vm_eval.c: ditto.
* vm_core.h: add comments.

for few years because:
* NODE is no longer accessible.
* rb_iseq_eval_main crashes without preparing with rb_thread_t.
* some existing APIs calls exit(3) without giving the opportunity to
finalize or handle errors to the client.
* No general-purpose function to compile a source to an iseq are
published in the public headers.
This commit solves the problems.

(ruby_setup, ruby_compile_main_from_file,
ruby_compile_main_from_string, ruby_eval_main,
ruby_set_script_name): new APIs to embed CRuby.
(ruby_opaque_t) Opaque pointer to an internal data, to NODE or iseq
in particular.
* eval.c (ruby_setup): Similar to ruby_init but returns an error code
instead of exit(3) on error.
(ruby_eval_main): Similar to ruby_exec_node but returns the
evaluation result.
