Make BackgroundWorkerList doubly-linked

This allows ForgetBackgroundWorker() and ReportBackgroundWorkerExit()
to take a RegisteredBgWorker pointer as argument, rather than a list
iterator. That feels a little more natural. But more importantly, this
paves the way for more refactoring in the next commit.
