download.fp.o -> proxies and redirects

[Matt Domsch]

The last step in completing the download.fp.o move onto the proxy
servers is to remove the forced client redirect, and instead use a
local rewrite rule and proxy pass, just as mirrors.fp.o/mirrorlist
uses.

I think this is right, but want extra eyeballs.  Here's the diff.

and for reference, here's what mirrors.fp.o has this below.  The interesting rule is the second rewriterule.

<Location /mirrorlist>
RequestHeader set CP-Location /mirrormanager
</Location>
