In preparation for getting cross-process postMessage working in Chromium, we need an API to send message events to frames. We also need an API for adding event handlers to frames so that we can intercept message events to our proxy frames. While we could dispatch the message event to the document and let it bubble, we can't capture message events on the document (they are directly dispatched to the DOMWindow), so we at least need methods to add and remove event handlers. While we're at it, we might as well add an API so we can dispatch messages directly as well to be consistent with the same-process behavior.

Please wait for approval from fishd@chromium.org before submitting because this patch contains changes to the Chromium public API.

Do we need to worry about that introducing security holes through > privilege escalation? Comment added. I talked with Charlie and we both agree that it's an acceptable risk. WebKit already exposes these functions internally. Any users of this API will need to consider the fact that these events might be synthetic, though. I added a comment to that effect. >> Source/WebKit/chromium/src/WebFrameImpl.cpp:1861 >> + if (!event.isNull()) > > I think you should be able to assume that you are given a non-null event.
