Message that can be sent between the UI process and web process extensions.
A WebKitUserMessage is a message that can be used for the communication between the UI process and web process extensions. A
WebKitUserMessage always has a name, and it can also include parameters and UNIX file descriptors. Messages can be sent from a
WebKitWebContext to all web process extensions, from a web process extension to its corresponding WebKitWebContext,
and from a WebKitWebView to its corresponding WebPage (and vice versa). One
to one messages can be replied to directly with send_reply.
