It currently isn't possible to suspend a channel from onHeadersReceived for a
cached response. And since it's not possible to add a new stream filter after
a response has started, adding a stream filter at that point will crash if the
channel is still registered.
This test is a basic sanity check for that scenario.

Bug 1400459 devirtualized nsIAtom so that it is no longer a subclass of
nsISupports. This means that nsAtom is now a better name for it than nsIAtom.

We don't use the initial Map returned by ChannelWrapper as a map, so there's no
need for the overhead involved in creating it. We also don't need the header map
generated by HeaderChanger unless headers are actually being modified, which
for many listeners they never are, so there's no need for the map creation and
string lower-casing overhead prior to modification time.

This allows us to reuse the same URLInfo objects for each permission or
extension that we match, and also avoids a lot of XPConnect overhead we wind
up incurring when we access URI objects from the JS side.

Ehsan, can you please review the (trivial) WebIDL changes, and Shane the
WebRequest logic?
The change to allow strings in MatchPattern arguments removes a huge amount of
XPConnect overhead that accumulates when creating nsIURI objects for
WebRequest processing.
The change to re-use existing URI objects removes a huge amount of URI
creation overhead.

Ehsan, can you please review the DOM bindings, and Shane the request logic?
The bulk of the overhead WebRequest API is in its access to nsIChannel and
friends through XPConnect. Since it's not really feasible to convert channels
to use WebIDL bindings directly, this generic channel wrapper class serves the
same purpose.
