* Rename `rb_scheduler` to `rb_fiber_scheduler`.
* Use public interface if available.
* Use `rb_check_funcall` where possible.
* Don't use `unblock` unless the fiber was non-blocking.

Onigumo 6 (r57045) introduced new onigumo.h header file, which is
required from quite much everywhere. This commit adds necessary
dependencies.
Note: ruby/oniguruma.h now includes onigumo.h,
ruby/io.h includes oniguruma.h,
ruby/encoding.h also includes oniguruma.h,
and internal.h includes encoding.h.
