Network cleanup (#6302)
* Cleanup network headers
* Move peerhandler to a specific header to reduce compilation times
* Move socket.cpp/h to network folder
* More work
* Network code cleanups
* Move socket.{cpp,h} to network folder
* Move Address object to network/address.{cpp,h}
* Move network exceptions to network/networkexceptions.h
* Client: use unique_ptr for Connection
* Server/ClientIface: use shared_ptr for Connection
* Format fixes
* Remove socket.cpp socket.h from clang-format whitelist
* Also fix NetworkPacket code style & make it under clang-format
