Being this a signal fixes two problems:

 - It allows you to set dynamic data, in case of multiple web processes you might want to set different data for each web process, like a unique id, for example. We might use that to make sure that the dbus names used by the web extensions are different.

 - It sets a place to initialize the web extensions directory (and this user_data).

> I think it would be better to call this "initialization parameters" instead of extra data, so it's clearer what they are for. I thought at first that they would be something that can be sent at any point rather than just for initialization.

what about initialization_user_data? which is what wk2 uses internally?
