replicate: don't stop checking xattrs because one was absent
The functional issue is described by the subject line. This patch also addresses several efficiency/structure issues, such as... * Calling dict_set_ptr once for each txn type, instead of once overall. * Calling afr_index_for_transaction_type once per iteration instead of once per call (or better yet zero since the conversion is unnecessary). * Implementation of inner functions in a different file than their one caller, creating a spurious header-file dependency.
