WebKit on Mac OS X already supports this and most other ports as well. Adding
it to a platform does not require any changes to WebCore.
The frame policy functions in FrameLoaderClient are the hook for this sort of
thing, specifically dispatchDecidePolicyForNavigationAction. WebKit looks at
the URL and decides it’s something an application can handle based on the
OS-specific system for handling such things. Then if it does want to handle it,
it calls the frame policy function with the action "ignore", which prevents
WebCore from doing anything with the link, and then passes the URL on to the
other application.
