db: drop most lazy joins
Lazy joins will in some cases turn small selects into joins that returns huge
amounts of redundant data - increasingly bad as the repo size increases.
Lazy joins should only be used after careful analysis and with comments
explaining the case.
This change will make some operations faster and probably also make some
operations slower. Performance regressions would have to be analyzed and
addressed separately ... and differently.
