Implemented download speed based URI selection algorithm.
Introduced new option --uri-selector.
If --uri-selector=feedback is given, aria2 uses download speed
observed
in the previous downloads and chooses fastest server in the URI
list.
Currently at most 10 URIs are considered to introduce
randomeness for
finding better servers. The speed is average download speed in
the
downloads.
On the other hand, if --uri-selector=inorder is given, which is
default,
URI is tried in order in URI list.
The usage text for the new option has not been written yet.
