Add a new function `mrb_exc_protect()`.
`mrb_exc_protect()` takes two C functions, `body` to be executed first,
and `resc` to be executed when an error happens during `body` execution.
Since `mrb_exc_protect()` should be compiled with the proper compiler,
we will not see the problem like #5088 that was caused by `setjmp()` and
`throw` mixture.
