Add support for re-generating the list continuously when restarting.

This generates a new full list, starts a fetch process to download all the
packages, and creates a new synthesized list excluding that stuff that was
merged already in the mean time (see
http://blog.flameeyes.eu/2010/04/18/squeezing-more-performance-out-of-the-tinderbox
) for more details about the idea.

This still require manual intervention to set the head of the queue before
restarting.
