2018-01-24ruby/ruby.h: remove unnecessary exports from C-APInormal
Needlessly exporting can reduce performance locally and increase binary size. Increasing the footprint of our C-API larger is also detrimental to our development as it encourages tighter coupling with our internals; making it harder for us to preserve compatibility. If some parts of the core codebase needs access to globals, internal.h should be used instead of anything in include/ruby/*.

2017-05-31Improve performance of implicit type conversionwatson1978
To convert the object implicitly, it has had two parts in convert_type() which are 1. lookink up the method's id 2. calling the method Seems that strncmp() and strcmp() in convert_type() are slightly heavy to look up the method's id for type conversion. This patch will add and use internal APIs (rb_convert_type_with_id, rb_check_convert_type_with_id) to call the method without looking up the method's id when convert the object.
