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.
