It would be really nice to push all of this back up to the parent or to at
least make it asynchronous. I think it should be possible since we control
when we send the DOM events, but for the moment this should work.
With this patch, I extend ProxyMIMEInfo and HandlerInfo with information about
the available extensions for a given MIME type. On Linux, at least, we read
the system (in my case GNOME) registry in the child and handlers.json in the
parent finally merging them again in the child (in
ContentHandlerService::FillHandlerInfo). Even though I was unable to get my
mochitest to work, it did work well enough that I could verify that this patch
was getting all of the proper extensions to the nsContentAreaDragDrop.cpp
code.
