Move towards using external binaries / RPC plugins

- First RPC steps

- Work on some flaws in RPC model

- Remove unused TLS settings from Engine and Swarm options

- Add code to correctly encode data over the network

- Add client driver for RPC

- Rename server driver file

- Start to make marshal make sense

- Fix silly RPC method args and add client

- Fix some issues with RPC calls, and marshaling

- Simplify plugin main.go

- Move towards 100% plugin in CLI

- Ensure that plugin servers are cleaned up properly

- Make flag parsing for driver flags work properly

Includes some work carried from @dmp42 updating the build process and
tests to use the new method.

+target="_blank">the Docker binary</a>.
 
-2. Download the Machine binary to somewhere in your `PATH` (for example,
-`/usr/local/bin`).
+2. Download the archive containing the Docker Machine binaries and extract them
+to your PATH.

+3. Check the installation by displaying the Machine version:
 
-1. Download the binary you want.
-2. Rename the binary to `docker-machine`.
-3. Move the `docker-machine` file to an appropriate directory on your system.
-
-    For example, on an OS X machine, you might move it to the `/usr/local/bin`
-    directory.
-
-4. Ensure the file's executable permissions are correct.
-5. Apply executable permissions to the binary:
-
-        $ chmod +x /usr/local/bin/docker-machine
