Pull request description:

  This is a refactoring PR that does not change behavior in any way. This change:

  1. Creates abstract [`Node`](https://github.com/ryanofsky/bitcoin/blob/pr/ipc-local/src/interface/node.h) and [`Wallet`](https://github.com/ryanofsky/bitcoin/blob/pr/ipc-local/src/interface/wallet.h) interfaces in [`src/interface/`](https://github.com/ryanofsky/bitcoin/tree/pr/ipc-local/src/interface)
  1. Updates Qt code to call the new interfaces. This largely consists of diffs of the form:

  ```diff
  -    InitLogging();
  -    InitParameterInteraction();
  +    node.initLogging();
  +    node.initParameterInteraction();
  ```

  This change allows followup PR #10102 (makes `bitcoin-qt` control `bitcoind` over an IPC socket) to work without any significant updates to Qt code. Additionally:

  * It provides a single place to describe the interface between GUI and daemon code.
  * It can make better GUI testing possible, because Node and Wallet objects have virtual methods that can be overloaded for mocking.
  * It can be used to help make the GUI more responsive (see https://github.com/bitcoin/bitcoin/issues/10504)

  Other notes:

  * I used python scripts [hide-globals.py](https://github.com/ryanofsky/home/blob/master/src/2017/hide-globals/hide-globals.py) and [replace-syms.py](https://github.com/ryanofsky/home/blob/master/src/2017/hide-globals/replace-syms.py) to identify all the places where Qt code was accessing libbitcoin global variables and calling functions accessing those global variables.
  * These changes were originally part of #10102. Thanks to @JeremyRubin for the suggestion of splitting them out.
