Extend initialization of URLRequestContextGetterQt to create a
content::ProtocolHandlerRegistry for each content::BrowserContext and add the
registry's URL request interceptor to the front of the interceptor chain.

Implement methods in WebContentsDelegateQt to add/remove protocol handlers
to/from the ProtocolHandlerRegistry.

Add permission request signal and classes for core, quick and widgets.

Add widgets autotest.

Add signal handlers to quicknanobrowser and simplebrowser.
