Allow multiple CacheDirs to be specified
This should hopefully allow multiple cache dirs to be specified in pacman.conf and/or on the command line, and allow pacman to test each one for the package file. The first one found to be writeable is used as the download cache. Signed-off-by: Dan McGee <dan@archlinux.org>
