Remove pmserver_t abstraction
Remove what was a pretty weird abstraction in the libalpm backend. Instead of parsing server URLs as we get them (of which we don't usually use more than a handful anyway), wait until they are actually used, which allows us to store them as a simple string list instead. This allows us to remove a lot of code, and will greatly simplify the continuing refactoring of the download code. Signed-off-by: Dan McGee <dan@archlinux.org>
