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.
