dev: Use shared_ptr for Arguments::Data
This patch takes a first few steps in transitioning from the ad-hoc RefCountingPtr to the c++11 shared_ptr. There are no changes in behaviour, and the code modifications are mainly introducing the use of make_shared. Note that the class could use unique_ptr rather than shared_ptr, was it not for the postfix increment and decrement operators.
