Added a RAII PcapHandle wrapper class that manages a Pcap handle.

[Dimi1010]

This PR adds a class PcapHandle that wraps a pcap_t* handle and manages the lifecycle of the handle via RAII mechanism, in a similar fashion to std::unique_ptr.

PS: The diff of PcapDevice.cpp is a bit messed up because the formatter ran on it... might be easier to review after #1516 has been merged.
