Make gencache more stable

This provides a compromise between stability and performance: gencache is a
persistent database these days that for performance reasons can not use tdb
transactions for all writes. This patch splits up gencache into gencache.tdb
and gencache_notrans.tdb. gencache_notrans is used with CLEAR_IF_FIRST, writes
to it don't use transactions. By default every 5 minutes and when a program
exits, all entries from _notrans.tdb are transferred to gencache.tdb in one
transaction.
