Applied AdaptiveURISelector patch from Aurelien Lefebvre. This
patch adds AdaptiveURISelector, which selects one of the bests
mirrors for first and reserved connections. For supplementary
ones, it returns mirrors which has not been tested yet, and if
each of them already tested, returns mirrors which has to be
tested again. Otherwise, it doesn't return anymore mirrors.
