When we send out a prefetch request, we act as if the load came
from one of the possibly many documents containing <link> element
for the given URL. The docgroup assigned to this request is
derived from this document. Later, when the load finishes, the
OnStopRequest code runs in a runnable labeled with this
docgroup. OnStopRequest dispatches a load event to *all* the link
elements, including some that might be in different docgroups
from the OnStopRequest runnable. This generates an assertion.
To fix this, I decided to dispatch the load events
asynchronously. I'm hoping the extra round trip through the event
loop shouldn't hurt us too much since I doubt anyone actually
listens for these events.

I still don't completely understand why we sometimes need to use the global
and sometimes the node. As far as I understand it:
- Not all event targets are nodes, so the node code can't always be used.
- The nsINode::GetOwnerGlobal implementation uses GetScriptHandlingObject,
which returns null in some cases where GetScopeObject doesn't. Here
is one:

Also I found that mBubbles are not initialized in the constructor in
AsyncEventDispatcher.cpp. I initialized those bool member variables
directly.

The bulk of this commit was generated with a script, executed at the top
level of a typical source code checkout. The only non-machine-generated
part was modifying MFBT's moz.build to reflect the new naming.
CLOSED TREE makes big refactorings like this a piece of cake.

This patch renames DispatchChromeOnly flag to OnlyChromeDispatch. With
this patch, if OnlyChromeDispatch flag is set, and the target is already
a chrome node, the dispatch path will start from the target. Previously,
even if the target is a chrome node, the dispatch path starts from the
parent target of the owner window of the current node.
