- widely adopt the use of ybt abstractions instead of raw dbt management. TODO: the loader and the descriptor are still manually managed. - remove templates from the perf framework in favor of explicit key size checks that more accurately describe "How Keys/Vals Work", and prevent type related bugs. - also: removed some dead code, refs #5101 git-svn-id: file:///svn/toku/tokudb@51665 c7de825b-a66e-492c-adef-691d508d4ae1
