With the old process selector service implementation, non-cached loads
would skip the call into the process selector.
This implementation piggybacks atop the existing 'redirectTo' mechanism.
This is unfortunately not the perfect system for catching these loads,
as it doesn't provide an opportunity for performing a final process
switch before redirecting to a non-http channel. In addition, it doesn't
provide indication that a redirect is going to happen, causing
potentially unnecessary process switches.
Not all places where 'redirectTo' is supported use this mechanism. This
process switching mechanism is only checked in situations after
http-on-examine-response.
Potential future changes include:
1. Moving these checks closer to the real 'OnStartRequest' call (e.g.
in ContinueProcessNormal + ContinueOnStartRequest3). This would mean
that loads other than the final load will not cause process swaps.
2. Adding a callback before a redirect is performed, passing in the new
channel, and allowing modifications to be made. This would allow
performing a process swap before redirecting to a non-http(s)
channel.

This patch changes the way we set and handle the preferred alternate data type.
It is no longer just one choice, but a set of preferences, each conditional
on the contentType of the resource.
For example:
var cc = chan.QueryInterface(Ci.nsICacheInfoChannel);
cc.preferAlternativeDataType("js-bytecode", "text/javascript");
cc.preferAlternativeDataType("ammended-text", "text/plain");
cc.preferAlternativeDataType("something-else", "");
When loaded from the cache, the available alt-data type will be checked against
"js-bytecode" if the contentType is "text/javascript", "ammended-text" if the contentType is "text/plain" or "something-else" for all contentTypes.
Note that the alt-data type could be "something-else" even if the contentType is "text/javascript".
The preferences are saved as an nsTArray<mozilla::Tuple<nsCString, nsCString>>.

The mIsTrackingResource flag on nsIHttpChannel was split into two separate
flags depending on whether or not the resource is third-party. The correct
flag will be set by the channel classifier. Similarly, a new function was
introduced, GetIsThirdPartyTrackingResource(), for those consumers (like TP)
who only care about third-party trackers.
The existing function, GetIsTracking(), will continue to look at both
first-party and third-party trackers (the behavior since first party
tracking was added to annotations in bug 1476324).
The OverrideTrackingResource() function now allows nsHTMLDocument to
override both mIsFirstPartyTrackingResource and
mIsThirdPartyTrackingResource, but since this function is a little dangerous
and only has a single user, I added an assert to make future callers think
twice about using it to opt out of tracking annotations.
Currently, only the default storage restrictions need to look at first-party
trackers so every other consumer has been moved to
mIsThirdPartyTrackingResource or GetIsThirdPartyTrackingResource().
This effectively reverts the third-party checks added in bug 1476715 and
replaces them with the more complicated check that was added in bug 1108017.
It follows the approach that Ehsan initially suggested in bug 1476715. It
also reverts the changes in the expected values of the tracking annotation
test since these were, in hindsight, a warning about this regression.

NullPrincipal::Create() (will null OA) may cause an OriginAttributes bypass.
We change Create() so OriginAttributes is no longer optional, and rename
Create() with no arguments to make it more explicit about what the caller is doing.

In e10s, a channel created by parent does not have a reliable reference
to the inner window ID that initiated the request. Without that, the
channel must request that the content process log and blocked messages
to the web console. This patch creates a new ipdl interface to pass the
message from the parent to the child process. The nsCORSListenerProxy
also needs to keep a reference to the nsIHttpChannel that created it so
it can find its way back to the child. Additionally, the
HttpChannelParent needs to be propagated when creating a new channel for
CORS.
