Subject: mem: Use shared_ptr for Ruby Message classes

This patch transitions the Ruby Message and its derived classes from
the ad-hoc RefCountingPtr to the c++11 shared_ptr. There are no
changes in behaviour, and the code modifications are mainly replacing
"new" with "make_shared".

The cloning of derived messages is slightly changed as they previously
relied on overriding the base-class through covariant return types.
