Move `runtime.connectNative` and `runtime.sendNativeMessage` to
`addon_child`. Note: This does not change the behavior for launching the
native app, it is still launched from the main process.
Now ExtensionUtils's Port is also used for native messaging ports. Now
the behavior of `runtime.connect` and `runtime.connectNative` are
identical from the extension's perspective.
In particular:
- `disconnect()` does not throw when called again (bug 1287229).
- `onDisconnect` is called with error messages (tests will be added in
the next commit).

- Introduce a proxy for IPC messages to allow the following APIs
to be run out-of-process (ProxyMessenger):
* runtime.connect
* runtime.sendMessage
* tabs.connect
* tabs.sendMessage
* runtime.onConnect
* runtime.onMessage
- Update getSender in ext-tabs, make it independent of the context
(in particular do not throw an error when a message is received while
the tab is gone), and move it from MessageChannel to ProxyMessenger to
make sure that it works in webext-oop. MessageChannel lives in a child
process, whereas the TabManager (used by getSender) requires data from
the main process.
- Set the third parameter of `addMessageListener` to true in some places
to make sure that messages get delivered even after unloading the
context. This is needed for the next two points.
- Put the `messageManager` property in BaseContext, and let it be set by
`setContentWindow` - runtime.sendMessage/connect and tabs.sendMessage/
connect depends on this property, and using the frame message manager
makes sense.
- Unconditionally use the frame message manager in
runtime.sendMessage/connect instead of sometimes the cpmm.

- Use schema-generated runtime API for content scripts instead of
untyped API.
- Move logic that cannot be run in the main process to a new file.
Together with the previous patch that migrated the i18n API, this
concludes the fix for bug 1286712.
