[pacman-dev] [PATCH] Enable libfetch connection caching

[Dan McGee]

This will allow downloads to reuse connections if possible, which could make
big differences on perceived FTP speed as the connection won't have to be
reestablished each time. For the most part, HTTP requests wouldn't be using
keep alive anyway so this won't have an effect there.

I'm not enthused about having to do this with the library initialization,
but there isn't a much better place due to the fact that the loop over
databases occurs on the frontend and not the backend.
