I was able to bisect it at least- and it was me. I haven't looked into
why this broke it yet, but if anyone else wants to poke at it, feel

    Remove some useless abstraction and start db cleanup

    We have some useless abstractions like an alpm_db_rewind function. I've read
    somewhere that readdir() was the worst filesystem function call invented,
    and what do we do? Add a wrapper around it. Kill this abstraction and move
    some other things into be_files that should be there anyway because they
    are so tied to how a files backend works.
