dev: Use shared_ptr for EthPacketData

This patch transitions the EthPacketData 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 bool casting operator for the shared_ptr is explicit, and we must
therefore either cast it, compare it to NULL (p != nullptr), double
negate it (!!p) or do a (p ? true : false).
