Well, it bails too often. :)

We need to make sure EAPI defaults to 0 when using old metadata.  It seems like db_template.__getitem__() is a nice central place to do that (2.0.51-eapi-awareness-db_template.patch).  I made another patch for bindbapi.aux_get() which does the same for old metadata from binpkgs (2.0.51-eapi-awareness-bindbapi.aux_get.patch).
