Title: Improve Rubinius support for msgpack Ruby gem

These commits improve the support for Rubinius in the msgpack gem. It makes sure the msgpack gem doesn't use internals of MRI to handle some things, because emulating them makes it terribly slow in Rubinius. By using the functions available in MRI, this is not a problem.

It also improves how the st.h header is detected by not using the RUBY_VM define, but by letting extconf.rb detect whether it's present or not.
