Ideally we'd try to detect hover intent here, but the preload is relatively
cheap, so I don't think we have much to lose by starting out simple.

This patch adds the ability to run SingletonEventManager handlers in
different modes: sync, async, raw (no exception handling, arg cloning,
or asynchrony), or asyncWithoutClone. When you call the handler,
you're required to specify which variant you want.
Existing uses of SingletonEventManager are all converted to async calls.
Note that some of them were previously synchronous, but it didn't appear
to be necessary.
Also added a callOnClose for SingletonEventManager when the last listener
is removed.

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).

In Chrome, runtime.lastError is set when the port is disconnected
due to an error.
Here in Firefox we choose to set a new property "error" on the port
if the port disconnected due to an error.
Since onDisconnect fires at most once, port.error is set only once.

Unify implementation of fire and fireWithoutClone. `fireWithoutClone`
was running the callbacks synchronously. After this commit the callback
is run asynchronously. This is safe because the only user of this method
is `Port`'s `onDisconnect`.

This should have been a part of bug 1298810, but that only set the
argument for native messaging ports, which does not use Port from
ExtensionUtils. The port parameter must also be included in runtime's
Port.onMessage to avoid regressions when the port implementations are
unified and native messaging starts using runtime's Port.
Note that starting from this commit, multiple onMessage listeners
receive the same (cloned) message instead of a new clone per listener.
This is a side effect of using `fire.withoutClone` instead of `fire`:
`fire` clones all parameters, but ports are not cloneable so we have
to use `fire.withoutClone` instead. This change with regards to message
cloning is fully compatible with Chrome's messaging API (which also
passes the same message object to all `port.onMessage` calls).
