Merge #10809: optim: mark a few classes final

40a0f9f Enable devirtualization opportunities by using the final specifier (C++11) (practicalswift)
9a1675e optim: mark a few classes final (Cory Fields)

Pull request description:

  Using gcc's ```-Wsuggest-final-types``` and lto, I identified a few easy devirtualization wins:

  > wallet/wallet.h:651:7: warning: Declaring type 'struct CWallet' final would enable devirtualization of 26 calls [-Wsuggest-final-types]

  >coins.h:201:7: warning: Declaring type 'struct CCoinsViewCache' final would enable devirtualization of 13 calls [-Wsuggest-final-types]

  >txdb.h:67:7: warning: Declaring type 'struct CCoinsViewDB' final would enable devirtualization of 5 calls [-Wsuggest-final-types]

  >zmq/zmqnotificationinterface.h:16:7: warning: Declaring type 'struct CZMQNotificationInterface' final would enable devirtualization of 4 calls [-Wsuggest-final-types]

  >httpserver.cpp:42:7: warning: Declaring type 'struct HTTPWorkItem' final would enable devirtualization of 2 calls [-Wsuggest-final-types]
