Subject: use transactions in ldbadd, ldbmodify and ldbedit

The command line tools ldbadd, ldbmodify and ldbedit should operate
within a transaction to make them more efficient. The ldbadd tool in
particular is much faster when adding a large number of records if all
the adds happen within a transaction. Previously there was a
transaction per record.
