Attempt to fix up some of the brokenness around failed package loads
This is a bit of a mess, due to the fact that we have a progress meter running. It is also ironic that we are in the midst of a method named "commit" when we haven't done a damn thing yet, and can still fail hard if either a checksum or signature is invalid or unrecognized. Adapt the former test_md5sum method to be invoked for any of the various failure types, which at least gives the user some indication of what packages are failing. A second patch will be needed to actually show worthwhile error codes, but this is going to involve modifying the actual data passed with the callback. Signed-off-by: Dan McGee <dan@archlinux.org>
