Remove package name dependency from libalpm
Previously, package names must match a specified scheme or they will cause pacman add operations to fail. This is not a very intelligent or necessary way to act, so remove the dependency on the name of the package to be installed and read all relevant information from the metadata instead. This does have one causality to be addressed later- pacman cache cleaning functionality, which has never been phenomenal, just lost most capability. Signed-off-by: Dan McGee <dan@archlinux.org>
