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.

In order to optionally report the full hash back to Google, we need to keep it
around in the callback. While a prefix is not the same as a full hash (multiple
full hashes can map to the same prefix), in this case, the callback will only be
called when the full hash matches.

mBackgroundThread is an nsCOMPtr write on PBackground thread but read on main thread. We need to use
Mutex to ensure memory sync between multiple threads.

NotifyTrackingProtectionDisabled/NotifyTrackingResource/SetClassifierMatchedInfo updates tracking protection and safe browsing states from parent to child.
They should at least handled by child process before OnStopRequest. Move them to PHttpBackgroundChannel can ensure that.

OnStartRequestSent is used to ensure the execution order between OnStartRequest and all other messsages sent over PBackground.
IPC messages sent before OnStartRequestSent can be processed immediately while received by content process.
IPC messages sent after OnSartRequestSent need to be pending until OnStartRequestReceived is called.

PHttpBackgroundChannel is created by content process because PBackground IPDL
can only be initiated from content process. The background channel deletion is
controlled by chrome process while PHttpChannel is going to be closed or canceled.
BackgroundChannelRegistrar is introduced for pairing HttpChannelParent and
HttpBackgroundChannelParent since they are created over different IPDL
asynchronously.
nsIParentRedirectingChannel.continueVerification is introduced to asynchronously
wait for background channel to be established on the new channel during the
Redirect2Verify phase.

PHttpBackgroundChannel is introduced to deliver OnStopRequest/OnTransportAndData/OnProgress/OnStatus on background thread.
FlushedForDiversion/DivertMessages is moved to PHttpBackgroundChannel to ensure no more channel event are delivered after these two messages on the background channel.
OnStartRequestSent is introduced to synchronize the execution order between OnStartRequest (main thread IPC) and all other messages on PHttpBackgroundChannel.
